INTRODUCTION

The ThunderBolt™ Storm Detector is designed to detect andtrack thunderstorm activity within 75 miles of your location. Itprovides detection warning via text messages on the two-lineLCD (Liquid Crystal Display), the red and green indicator LEDs(Light Emitting Diode), and an audible tone. All of the opera-tions and functions for the ThunderBolt are selected from themain menu, and basic storm detection is automatic once theunit is powered on.

IMPORTANT! The ThunderBolt uses the latest electronic andcomputer technology to detect and track thunderstorms.However, thunderstorms can be a rapidly changing weatherphenomenon, and the information provided by theThunderBolt should always be used in conjunction with othersources of information. Remember that the ThunderBoltdetects ACTIVE storms, and cannot predict when or where aparticular storm may form, and/or where the first lightningstroke occurs.

GENERAL OPERATION

The ThunderBolt detects and tracks the motion of storm cellsby detecting the lightning activity within the cell. The unit iscapable of detecting multiple storm cells within its 75-mileoperating range, and is also capable of identifying squall linesand severe storms. (Super-cells are severe thunderstorms thatare typically larger and more violent than normal storms.They comprise approximately 10% of all thunderstorms.)

Once in basic Storm Scanning mode, the ThunderBolt™ warnsof any detected thunderstorm activity using text messages dis-played on the LCD. Depending on the exact type of weathersituation being detected, the information is displayed using arepeating series of two-line messages on the screen. Thesemessages cycle approximately every 10 seconds so that anyparticular message will reappear within a short period.

It is important to remember that the ThunderBolt continuallyaccumulates data from the ongoing storm activity and thatmore accurate information can be displayed with more data inthe computer memory. This makes it important to have theThunderBolt operating for as long as possible before stormactivity is nearby. Don’t wait until you think storms areclose before turning on the unit! If the ThunderBolt isturned on with Thunderstorm activity already close by,it may take several minutes for the most accurate infor-mation to be calculated and displayed.

IMPORTANT! Anytime the ThunderBolt displays detectedstorm activity immediately after power on, you should takeextra precautions until enough data has accumulated to givean accurate location of the storm. Storm activity should beassumed to be LOCAL and appropriate precautions taken untilat least fifteen minutes of storm data has been allowed to accu-mulate. This is especially important if the APPROXIMATERANGES displayed are 20 miles or less!

Once a storm approaches within 8 miles of the user location,the ThunderBolt warns that the storm is now LOCAL. It will

3

maintain this warning until the detected storm activity recedesto a distance of more than 8 miles. While the storm is local,the ThunderBolt™ will calculate and display the estimated timefor the storm to clear. Note this is only an estimate! The stormmotion may change while still in your vicinity, and the time forit to clear to a safe distance may change quickly!

IMPORTANT! Note that storms may form directly over yourlocation, and that advance warning of these storms may bevery limited!

The ThunderBolt continually analyzes the intensity of thestorm activity it detects, and attempts to provide additionalwarning about the presence and approach of both squall linesand super-cells. Once detected, warnings for these types ofstorms are displayed in the LCD. Both types of storms arecapable of producing high winds, severe rain, and tornadoes.Extreme caution should be taken if these warnings are dis-played. Also note that storm cells may evolve quickly from anormal cell into these more dangerous forms of weather.Always consult your local weather information sources, ifavailable, when the threat of these types of storms are present.

IMPORTANT! Keep in mind that all of the approach speedsand estimated arrival times are based on data that theThunderBolt accumulates over periods of time.Thunderstorms can change both their intensity andactivity on very short notice. The information displayedby the ThunderBolt must be used as an approximationthat can change quickly as the storm changes.

INSTALLATION AND SET-UP

The ThunderBolt™ is designed to operate either vertically(hand-held, using the wall-mount, or using the optional deskstand), or lying flat on a horizontal surface. The unit will NOTperform properly if oriented on its side.

The ThunderBolt contains special software routines for detect-ing and minimizing false triggering from non-storm sources. Aspecial noise-test feature should be selected from the mainmenu when first installing the ThunderBolt in a new location.This routine will take 15 minutes to run, during which itdetects and maps all the regular sources of electromagneticnoise in the vicinity.Once returned to normal operation, the ThunderBolt will ignorethese regular noise sources. The ThunderBolt also continuous-ly monitors the background electromagnetic noise level duringnormal operation. If the high local noise level lasts longenough to interfere with normal storm detection, theThunderBolt will display a warning message that indicates theunit must be relocated for accurate operation. This same mes-sage will be displayed during the normal Noise Test routine ifbackground noise level conditions are detected that will notallow proper operation and storm detection.

IMPORTANT! If the message "WARNING:HIGH BACK-GROUND NOISE" is displayed, turn the unit off, move it to adifferent location, and restart. As soon as any local stormactivity has cleared, the Noise Test routine should be selectedand run from the main menu. Until the Noise Test hasbeen rerun, the accuracy and detection sensitivity ofthe unit may be reduced.

5

The ThunderBolt™ is powered by a single 9-volt battery. It mayalso be powered by using the 115V-AC (or 220V-AC) adapteravailable from Spectrum Electronics, Inc. NOTE: The use of anon-specified adapter may cause inaccurate or improper oper-ation of the unit, and may damage the power supply circuitry.

Should you have any questions about the use or operation ofyour ThunderBolt, call Spectrum Electronics, Inc. at the toll-free customer service number shown in this manualbetween 9a.m. and 5p.m. EST. Or you may post a messagefor a customer service representative by logging on to theThunderBolt website at www.spectrumthunderbolt.com

IMPORTANT! Remember that the ThunderBolt is designedto detect and track storm cells and squall lines, not individualstrokes of lightning. A single stroke of lightning contains vari-ations due to amperage of the stroke, polarity, and orientationto the ground. All of these factors make it more dependableand accurate to analyze, detect, and track the entire storm cellas it moves. Thunderstorms are also large (6-10 miles across)with lightning activity appearing in different places within thebody of the storm, often simultaneously. Once a storm is local,lightning can appear at ANY TIME at your location! Takedefensive action before this situation develops!

BASIC OPERATION

1. Battery Installation

The ThunderBolt operates on one standard 9V battery. Clip theconnector over the terminals on the battery and securely closethe battery compartment door on the back of the unit. (NOTE:

6

The compartment door has been designed to provide a securefit to withstand rugged use. As a result, the compartment doormay initially be stiff and difficult to open. By using the bottomof your palm, place downward pressure on the door at thepoint between the EX. SPK. and 9V DC jacks, and then pushthe door away from the unit. The compartment door willbecome easier to open with each successive opening.)Remaining battery life is constantly monitored by the computer.A LOW BATTERY warning message is periodically displayedonce remaining battery life drops below approximately 5-7hours. The battery should ALWAYS be replaced as soon aspossible once the LOW BATTERY warning message is displayed.

2. External AC Adapter

The ThunderBolt™ may be powered by an approved low-noiseexternal adapter. The adapter jack is labeled “9V DC” and islocated on the back of the unit above the battery compartmentdoor.

If you occasionally detect incidences of false triggering whenusing the system on your AC Adapter, the problem is mostlikely voltage spikes on your AC power. Whenever possible, wesuggest you use standard surge protection to filter out the noise.

3. Power ON/OFF

Pressing the ON/OFF button on the front of the unit turns thepower on. The MAIN MENU appears on the display, and thegreen LED, located behind the lens at the top of the unit, blinksto indicate normal operation.

The SCROLL UP/DOWN buttons are used to move up and

7

down the items on the MAIN MENU. Selecting an item fromthe menu is done by moving the blinking cursor to the num-bered item desired, and then pressing the ENTER button. Afterinitial power-up, the ThunderBolt™ automatically begins normalstorm detection if no other button is pressed within 10 seconds.

The ThunderBolt is programmed to automatically turn off afterapproximately five hours if no buttons are activated. This ismeant to conserve battery life if the unit is accidentally storedwhile turned on. This automatic-off feature is disabled if theunit is being powered by the external 120V-AC adapter. Tomanually turn off the unit, press the ON/OFF button and holdthe button until a short alarm sound is emitted from the unit(approximately one second)—this delayed deactivation pre-vents the unit from getting turned off inadvertently.

4. Normal Operation

There are five user-selectable choices on the MAIN MENU:1. STORM DETECT 2. ALARM RANGE3. ALARM MODE 4. SENSITIVITY 5. NOISE TESTRemember that you can only view two lines of the menu atany one time. Use the SCROLL UP or DOWN keys to movethrough the menu options. Once in SCANNING mode, pressingand releasing either of the scroll keys will display the menu.Once in the menu, the unit will automatically shift to SCAN-NING mode if no other buttons are pressed within 5-7 seconds.

5. Tone Operation

The tone may be turned on or off any time the normal scan-ning screen is displayed by pressing the Tone ON/OFF button

8

on the front of the unit. To turn the tone off once stormactivity has been detected, first power off the unit usingthe ON/OFF button. Then restart the unit and wait forthe scanning screen to reappear before pressing theTone ON/OFF button. A “TONE IS OFF” message willbriefly be displayed and the unit will automaticallyreturn to normal scanning operation. The unit willquickly resume the current storm display.

STORM DETECTION

Selecting STORM DETECT puts the unit into normal stormdetection. Once the unit is powered on, it automatically goesinto STORM DETECT unless another key is pressed within 5seconds. Once SCANNING, the cursor will move back and forthand the selected SENSITIVITY (normal or high) will be displayed.

To change any of the user settings, press and release either of thescroll keys to call up the main menu. (Remember that you mayhave to scroll down to find the desired menu item for selection.Only two lines of the menu will be visible at any one time.)

Once initial storm activity is detected, the screen will display awarning that strikes have been detected, and then the range inmiles to the last CLOSEST strike detected. This information willbe displayed and updated until enough data has been accumu-lated to display the range to the leading edge of the storm,along with indication of storm motion. The time required foraccumulation of this data may vary depending on the actuallevels of activity within the storm. If no movement toward youhas been detected, a NO APPROACH DETECTED message will

9

be displayed along with storm distance. If the storm isapproaching, the storm speed, along with Estimated Time ofArrival (ETA) in you area will be displayed.

IMPORTANT! The ETA displayed is the estimation of whenthe leading edge of the storm activity will reach within 8 milesof your location. This may happen without any obvioussigns of storms being directly overhead.

Once any part of storm cell activity has been detected within 8miles of your location, the screen display will indicate STORMIS LOCAL. This means that lightning activity directly overheadis now possible at any moment, and extreme precautionsshould be taken! Once a storm has become LOCAL, an esti-mated TIME TO CLEAR will be displayed. This time estimate isbroken into 15-minute segments, and is updated as storm datacontinues to be collected. The estimate displayed may changeor run longer based on the actual storm activity. This will oftenhappen with storms that develop directly overhead with verylittle associated movement.

IMPORTANT! Remember that most storms detected at rangesgreater than 20 miles will appear to be approaching, and willbe given an ETA, until enough data is accumulated to be cer-tain of passing safely out of local danger range. In actualoperation, this will mean that storms detected at long range willappear to gradually veer off from your location. In actuality, theThunderBolt™ may warn of a potential storm strike until enoughdata indicates there is little or no possibility of a direct hit. Formost storm situations, the ThunderBolt will be able to determinethe likelihood of a direct hit or near pass from the storm by the

10

time it has closed to within 15-20 miles. Storms displayingranges of less than 20 miles and ETAs of less than 30minutes are HIGH LEVEL threats and should triggermaximum safety responses.

The ThunderBolt™ constantly analyzes the incoming data forsignatures of squall lines and super-cells. If either of these con-ditions is detected, a text message appears on the screen. Bothof these weather patterns are HIGH LEVEL threats for highwinds and possible tornado activity. Extreme caution should beexercised when these conditions are approaching your location.

Once storm activity approaches within 8 miles of the user’slocation, the screen displays a STORM IS LOCAL warning.The ThunderBolt then calculates the expected time for stormactivity to clear the user’s location. (Clearing a locationmeans NO detected storm activity within eight miles for15 minutes. If any activity at all occurs while the stormis local, the Time to Clear will reset itself.)

IMPORTANT! The Time to Clear is updated continuously usingactual storm speed, as well as the approach of storms outsidethe 8-mile local zone. Keep in mind that these factors maycause the Time to Clear estimate to change and lengthen onceit begins. Also note that this is ONLY intended as an estimateof the time necessary to completely clear dangerous activity fromyour location. Storm motion and activity can occur faster than theThunderBolt can accumulate enough data for accurate estimates.

ALARM RANGE

Selecting this option allows the user to choose the warning rangefor activation of the red LED and the audible tone. Warningranges are selected by using the SCROLL UP/DOWN buttons totoggle the displayed range in miles to the value desired. Pressingthe ENTER button stores the value in memory. Once stored,these values will be used every time the unit is operated untilchanged. NOTE: The audible tone may be turned on or off atany time by using the front panel button. This will not changethe alarm range stored in memory. Please note: each time theunit turned on, the audible tone will be on, and must be turnedoff manually.

ALARM MODE

Selecting this option allows the setting of an additional triggerdistance for an audible alarm with a faster tone rate. This featureallows the ThunderBolt™ to automatically increase its alarmlevel as a storm approaches to a closer distance than the rangeselected for normal storm detection.

SENSITIVITY

Selecting this option allows the user to select either a HIGH orNORMAL storm detection sensitivity. HIGH sensitivity willmaximize the distance at which storms are detected and track-ing begins. It will tend to plot storms as closer and approachingfaster than they might actually be, and should be used in situa-tions where maximum caution and time are required to preparefor storm arrival. The HIGH sensitivity setting may also be usedin certain indoor applications where the surrounding buildingmay be reducing the received signal strength.

11

12

The NORMAL setting produces greater accuracy in stormtracking and speed calculation, but increases the time betweena storm first being detected, and a calculated speed and ETAbeing displayed on the screen.

BACKGROUND NOISE TEST

This option runs up to a 15-minute sampling routine whichdetects and maps the periodic noise sources in the plannedoperating location for the ThunderBolt™. Once completed, thisallows the unit to ignore regular, non-storm electromagneticinterference (EMI) in the environment. If the background EMIat the selected location is too high to allow normal storm detec-tion, a warning message will be displayed, indicating that theunit must be moved to a different location for proper operation.Otherwise, the unit will automatically return to the mainmenu. NOTE: Pressing ENTER, or any other button, willstop the noise test routine before completion. No datawill have been stored and the test will need to be runfrom the beginning at a later time. The Noise Test shouldbe rerun periodically to ensure accurate operation.

IMPORTANT! The noise test MUST be run when no realstorm activity is occurring within 50 miles of yourlocation. Running the noise test with actual storm activitywithin range will introduce errors and inaccuracy to the normaloperation of the ThunderBolt, and may decrease the operatingsensitivity of the unit.

THUNDERBOLT™ LCD TEXT MESSAGES

What do they mean?

ThunderBolt™ has been programmed to communicate certainmessages during specific weather conditions. In normal opera-tion, the user will see a repeating series of messages specific tothat situation. The following list describes the most commontext messages the user will encounter using the ThunderBolt,along with a brief explanation. These explanations mayanswer questions the user may have during certain weatherconditions. It is important to note that due to space limitations,as well as memory limitations, ThunderBolt provides messagesprogrammed into the software and cannot necessarily elaboratedue to such limitations.

SCANNINGSENSITIVITY HIGHThunderBolt is scanning and has not detected any storm activity.This option provides the fastest possible information, sacrificingaccuracy for speed. The information will gradually become moreaccurate as the unit gathers more data. Use this option in situa-tions where maximum warning time is required to prepare forstorm arrival, or in certain indoor applications where the sur-rounding building may be reducing the signal strength.

SCANNINGSENSITIVITY NORMALThunderBolt is scanning and has not detected any storm activity.When using this option, a longer period of time is necessary forspecifics of any storm activity to be indicated.

16

NOTE: Both HIGH and NORMAL modes are effective andselection by the user should be made based on preferenceand/or application needs.

WARNING!STRIKES DETECTEDThunderBolt™ has detected initial lightning activity. The nextscreen will follow:

CLOSEST ACTIVITY______ MILESThe ThunderBolt has detected storm and is in the process ofinitial ranging. The display represents the closest detectedstroke during the period of initial data collection.

STORM ACTIVITY______ MILESThunderBolt has plotted the storm location. Storm approachspeed and ETA (estimated time of arrival) will follow if thestorm is approaching.

SEVERE STORMThunderBolt has detected a severe storm. Please take properprecautions, including checking other weather sources foradditional information and advisories.

SQUALL-LINE OR MULTIPLE STORM CELLSThunderBolt has detected the presence of squall lines or multi-ple storm cells. ThunderBolt provides storm information closestto the user.

17

APPROACH SPEED ____ MPHThunderBolt™ has determined that the storm is approachingthe user at the indicated speed. This information does notalways mean the storm will reach the user, as storms cansometimes change direction or dissipate.

STORM ETA _______ MINUTESThunderBolt has calculated the storm distance and approachspeed and determined, based on current conditions, that thestorm will reach striking distance of the user in the timeestimated on the screen.

WARNINGSTORM IS LOCALWhen this message appears, seek safe shelter. The storm hasmoved within eight (8) miles and is now within striking distanceof the user. NOTE: the user may not yet hear or see lightning(perhaps looking at blue sky/non-threatning conditions) asthe storm may be on the edge of the eight mile range (wellbeyond the range of seeing or hearing storm activity). Thisrepresents one of the most dangerous situations (commonlyreferred as the Bolt out of the Blue), as the user’s commonsense may disregard the ThunderBolt warning due to perceivedconditions. WARNING: 30% of all lightning victims arestruck on the front edge of the storm. Rely onThunderBolt and other weather sources and seek safe shelterduring this warning.

18

WARNINGSTORM LOCAL____ MILESThis is not a common screen and will appear only when astorm develops within the eight mile LOCAL range. There willnot be any previous storm warning on the unit because thestorm developed within this range. This occurrence is morecommon in subtropical and tropical regions when small stormcells can develop rapidly during summer season.

TIME TO CLEAR____ MINUTESOnce storm activity has become LOCAL (within eight milesof the user), the ThunderBolt™ will indicate, based on currentconditions, the amount of time it will take for the storm tosafely clear the eight mile range. The unit is limited to threetime frames (15, 15-30, and 30 minutes). Once this timeappears, ThunderBolt internally begins a countdown of thistime. If during this countdown, the ThunderBolt detects any newlightning strokes within the eight mile range, it will automaticallyreset the time back to the time it originally indicated. Therefore,the TIME TO CLEAR time can be greater than indicated as theunit detects new activity.

Once the unit has completed its internal TIME TO CLEARcountdown, it will resume normal scanning activity (indicatedon the screen) and it is safe to resume outdoor activities.

19

QUESTIONS ABOUT OPERATION

The ThunderBolt™ indicates STORM IS LOCAL, but novisual indication of a storm nor any audible thunderoccurs.

Most likely, this is indicative of very low intensity electricalactivity coming from a cloud formation(s), but may not be (orbecome) a storm as we typically define a storm.

While this is a common phenomenon in subtropical or tropicalclimates, it can also occur most anywhere. It represents one ofmost dangerous weather situations because there is no visualor audible danger. Yet a "bolt out of the blue" can occur fromthis situation, resulting in many of the annual lightning deathsand injuries suffered worldwide. This is an instance when youshould not put your faith in your own common sense. Use theThunderBolt, as well as all other weather sources available toyou, to help make the safest decision in this situation.

Another possible reason may be the location of theThunderBolt. Is the unit being used near a computer or otherelectronics? These and other high noise sources can cause theThunderBolt to false trigger. Move the ThunderBolt away fromthe possible source of interference and re-run the noise testroutine.

I hear thunder and/or see lightning, but ThunderBolt isnot indicating “Storm is Local.”

20

There are several possible reasons for this occurrence.

1. Unit was turned on after activity has approached the area.ThunderBolt™ is designed to gather storm data and provide theuser with storm information based on the data it has analyzed.If turned on at first indication of storm activity, it will take ittime (which will vary depending on the intensity of the storm)to gather enough data to provide accurate information.

ThunderBolt will provide the most useful and accurate infor-mation when turned on and in use through the duration of alloutdoor activity.

2. Unit is getting used at a new location and the noise test hasnot been conducted. A noise test should be conducted whenmoved to a new location to assure most optimal operation.WARNING: Do not conduct a noise test during storm activity,as this will DESENSITIZE your ThunderBolt.

3. Activity may be cloud-to-cloud lightning. Cloud-to-Cloudlightning are lightning strokes within the cloud, but not emit-ting strokes to the ground. At night, such activity can literallylight up the sky. There may also be audible thunder with thisactivity (generally a low rumble). The ThunderBolt, recognizesthis activity, but will not indicate it because it is not necessarilya dangerous situation. ThunderBolt will provide detectionwarning should the activity develop into cloud-to-ground light-ning strokes. This is a situation where your common senseshould be exercised, and precaution becomes the prudent thingto do.

21

4. Activity may have developed within local range and lowintensity. A common occurrence in subtropical or tropical climates,or any region similar to Florida. This is a situation when toolittle data has occurred for the ThunderBolt™ to respond quickly.Again, this is a situation when your common sense should beexercised and precautionary measures become prudent.

5. If none of the above explanations appear to apply, pleasecall Customer Support at Spectrum Electronics toll free at(877)738-7330.

Storm appears to have cleared, but the ThunderBoltcontinues to display “Time to Clear” information.

Storm may be out of your visible or audible range (4-6 milesor less), but may still be within 8 miles. CAUTION: 60% of alllightning victims are struck after the storm has passed.

ThunderBolt’s Time to Clear feature has been designed to countdown the estimated Time to Clear time before it goes back tonormal scanning mode. Should any lightning stroke occurwithin 8 miles during this countdown, ThunderBolt will auto-matically reset the Time to Clear back to the original estimatedtime (15 minutes is the minimum time increment). Due to thisfeature, it is possible the activity has cleared while ThunderBoltis in its countdown. To verify, you can turn the unit off for 30seconds to reset and then turn it on. ThunderBolt will go into ascanning mode; if no activity is detected then the storm hasmost likely cleared the “local” area.
