Continue from 3-1 ,test mode condition.

Connect up the circuit as shown below.

Access channel 7, 30.225MHz, by pressing “PAGE” key.

Switch position S402 +PULSE Tx: “ON”

Through the frequency counter ,confirm the unit is transmitting

in 30.225MHz by aligning CT1 01.

Confirm the transmission power is 6.OdBm +2.5dBm through

the RF Voltmeter with the 50 ohm adaptor.

Tx MODULATION 1. Mute the Rx by soldering a220pF

at R31O to GND.

2. Adjust AF oscillator to 1KHz, and the

output level at the ACVM is -20dBm.

3. Align VR601 to obtain 2.0 kHz *0.1

detector 3.3 kHz *0.45 kHz dev.

h) TX DATA MODULATION

1. After Tx modulation alignment

,disconnect DC 9V from the unit and

short 33 pin and 5 pin (IC401 )to

ground. then connect DC 9V to the

unit ,and push PAGE key.(TX DATA

is sent.)

2. Check the read of linear detector is

3.5 kHz *1.0 kHz dev.

3. After Transmitting Alignment,open

33 pin and 5 pin(lC401 )from ground

and dis-solder Elect cap 220LF/1 OV

i) CD Level Adjustment

Change output level of FM SSG from 46 dBm to 10 dBm.

Align VR301 anti-clockwise so that the DC voltmeter just turn

to Low,then align VR301 clockwise so that the DC voltmeter

just turn to Low.

Confirm the CD Level is Low by changing the FM SSG output
