Test Segment 10 of 60
Program µC IC and Current draw Audio board only
CAUTION When reprograming already tested devices, be sure to set device programmer GUI to preserve all settings (block,
limiter settings, etc.). In Microchip MPLAB this is done by selecting Programmer > Settings > Program > Preserve
EEPROM on program > Apply > OK. Failure to do so will result in loss of all assigned variable values such as
frequency block, limiter setting, indicator settings, etc.
Note This need only be performed at the factory the first time the DUT is powered up, when µC IC is replaced, or when a
firmware update is desired and confirmed to be appropriate.
Apply +3.0VDC, 300mA current limit in at battery contact J8 (J9 is circuit common)
Note In order to program DUT, JU1 must be jumpered or the power button must be pressed during the entire programming process. Remove JU1 jumper after programming.
Program µC IC with programming cable connected at J6 (ICSP port)
Remove ICSP cable
Measure current draw 50 to 500 mA (117)
Note The goal here is only to ensure the audio board powers up and is not burning up with fever

Remove DC voltage from Battery contacts and apply firmware version label to audio board

Note Power Measurement are made with the output of the DUT connected directly to the power measuring device to ensure measurement is as accurate as posable .
Using the test key pad navigate to the "PwrCal" screen
Note
This sets the DUT to "L" (50mW) carrier power at the Mid carrier frequency, from here pressing the UP or DWN
buttons adjusts carrier power. Pressing MENU/SEL button once will move to the Low carrier freq. UP and DWN
buttons adjusts carrier power. Press MENU/SEL again moves to the highest frequency, UP and DWN buttons
adjusts carrier power. Pressing MENU/SEL once more moves to "H" (100mW) at the Mid freq and the pattern
continues to set power for 100mW..
