1. Connect an RF signal from an encoded Marti transmitter adjusted for proper encode
frequency and modulation level as an encode signal source to the receiver.
2. Operate the multimeter to DECODE LEVEL.
3. Adjust SENSITIVITY control R1 for approximately 2 volts p–p on the front panel meter.
4. Adjust DECODE FREQUENCY control R7 for maximum signal on the front panel meter.
5. Re–adjust SENSITIVITY control R1 for approximately 2 volts p–p on the front panel meter.
6. Adjust relay control R16 so that relay K1 just closes at this level.
7. Remove the test equipment.
8.3 POWER SUPPLY/METER CALIBRATION
1. Connect a voltmeter between TP–17 and ground on the front panel circuit board.
WARNING
AC LINE VOLTAGE IS PRESENT ON THE POWER SUPPLY TERMINAL STRIPS.
DO NOT TOUCH THE TERMINAL STRIPS DURING THE FOLLOWING
ADJUSTMENT.
2. Adjust SVR1 on the power supply for a +12V dc indication on the multimeter.
3. Operate the multimeter switch to POWER SUPPLY.
4. Adjust R65 on the front panel circuit board for a 12V indication on the multimeter.
5. Remove the test equipment.
