Remarks

Connect the RF power Meter to the RF test point on the handset MAIN PCB.
Adjust RT601 for a -5.0dBm reading on the Power Meter.

Connect the Frequency Counter to the RF test point on the handset MAIN
PCB. Adjust CT601 to make sure that the frequency is 903.052467 MHz.

Press the “2” key to enter the TEST Mode 2. Connect the AF Generator to
the MIC Connector. Make sure that the output is 1kHz 9mV from the AF
Generator.
Connect the Deviation Meter to the RF test point on the handset MAIN PCB.
Adjust RT602 to indicate

±

8 kHz Dev.

Preset

a) Connect DC power supply to battery connector on the handset unit.
b) Turn the DC power supply ON while pressing “

∗

” and “ # ” keys, and keep pressing the keys continuously for

approximate 2 seconds.

c) Release keys when entering TEST mode 1 with TALK LED lighting and beep.
