HOW TO USE THIS MANUAL

Use the front cover locator and marked pages to quickly find the parts of the

manual shown on the cover. These portions of the manual were chosen because they

are used most often. Inside, the manual has been divided into chapters, sections,

and paragraphs which are all numbered sequentially.

Finding the Instruction You Need.

1. How do you start?

Look at the front cover of this manual. On the right side you will find the list-

ing INTRODUCTION. The locator tells you to go to Page 1-1. You must familiarize

yourself with M81 Simulator and its components before you begin any task.

2. What do you do if you have a failure?

Look at the symptom index on Page 4-2 and find your symptom. The symptom index

will tell you where to find the appropriate troubleshooting procedure. If, for

example, none of the receivers respond to the transmitter, you will find this

symptom in Paragraph 4-9e.

3. How do you fix a problem?

Follow the instructions in the troubleshooting table. Follow the procedure until

the problem is fixed.

4. What if these procedures still do not fix the problem?

Obtain a new simulator.

Simulators are obtained from Training Audio-

visual Support Center (TASC).

CAUTION

Any attempt to mount a transmitter tone module

in a receiver or vice-versa could damage the

equipment.

1. Last digit of SERIAL number printed on replacement tone module should be 5.

Last digit 1, 2, 3, or 4 would identify receiver tone module. Record

SERIAL number of transmitter tone module on piece of paper.

N O T E

Be sure first three digits of transmitter tone

module SERIAL number match first three digits

of SERIAL number on receiver tone modules.

4. Pull up on detector carrying handle until detector internal com-

ponents clear rim of case-bottom assembly.

5. Position case-top assembly so word CAUTION and black radiation

hazard symbol on one face of case-top assembly are up, internal

components point up at an angle to your right, and case-top assembly

rests on carrying handle and one top edge.

6. Locate 14-pin Test Connector J1O (5).

Position receiver on flat surface so receiver ring is up, extender is

down, and coaxial connector (7), is to your left.

Looking down into receiver ring, locate Connector P1 (8) on decoder

printed wiring assembly.

Position case-top assembly above receiver ring so word CAUTION and

black radiation hazard symbol are toward you.

CAUTION

The M43A1 Interface Cable must not interfere

with electrical spring contacts or Interface

Cable Retainer on inside of ring or extend

between case-top assembly and receiver ring

top surface or damage may result.

While guiding M43A1 Interface Cable out thru bottom of receiver

ring, lower detector internal components into receiver ring. Be sure

none of M43A1 Interface Cable extends between case-top assembly and

receiver ring top surface. Be sure cable does not interfere with

electrical spring contacts (9) or Interface Cable Retainer (10) on

inside of receiver ring.

No special equipment/materials required.

Before performing the following steps, be sure that the following

procedures have been performed.

1. Installation of receiver ring in M43A1 Detector (Paragraph 4-

15b) .

2. Installation of receiver antenna (Paragraph 4-14b).

Separate each M43A1 Detector, with receiver installed, from the

transmitter by approximately 20 meters (66 feet). The

receiver/detectors should be within line-of-sight of the

transmitter.

Turn the Transmitter CHAN SEL switch to select a channel matching

the UNIT digit of the receiver to respond.

Be sure the antenna is pointing straight up, the operating plate is

toward you, and you are facing the receivers. Switch to OPR and

hold there for 5 seconds. Release the switch.

Reset detector by pressing the BATTERY TEST AND RESET PRESS button.

The BATTERY TEST AND RESET PRESS button may have to be held down for

60 seconds.

Repeat Steps c, d, and e for each of the receiver/detectors.

Was brought to you by me:

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.

I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
