Note Red LED (D300) and Blue LED (D301) do not glow in this case6 Long press MFB button (SW701) to turn ON the system and keep pressing the MFB button to enter into

Pairing mode Once the system is turned ON the Red LED (D301) and the Blue LED (D300) blink alternatelyto indicate that the device has entered into Pairing mode

7 The following steps help in pairing between BM83 module and a smartphone71 Turn ON the smartphones Bluetooth to scan for the discoverable devices72 Select the module device name ldquoBM83rdquo from the scan results73 Enter 0000 as passcode to pair the smartphone with the BM83 module The passcode is not required

if simple pairing is enabled in the Config Tool

The smartphone displays ldquoConnectedrdquo upon successful pairing as highlighted in the following figure The audio canbe listened over the headphones

Microchip Devices Code Protection FeatureNote the following details of the code protection feature on Microchip devices

bull Microchip products meet the specification contained in their particular Microchip Data Sheetbull Microchip believes that its family of products is one of the most secure families of its kind on the market today

when used in the intended manner and under normal conditionsbull There are dishonest and possibly illegal methods used to breach the code protection feature All of these

methods to our knowledge require using the Microchip products in a manner outside the operatingspecifications contained in Microchiprsquos Data Sheets Most likely the person doing so is engaged in theft ofintellectual property

bull Microchip is willing to work with the customer who is concerned about the integrity of their codebull Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code Code

protection does not mean that we are guaranteeing the product as ldquounbreakablerdquo

Code protection is constantly evolving We at Microchip are committed to continuously improving the code protectionfeatures of our products Attempts to break Microchiprsquos code protection feature may be a violation of the DigitalMillennium Copyright Act If such acts allow unauthorized access to your software or other copyrighted work youmay have a right to sue for relief under that Act
