(TYPICAL CONTROL SETTINGS)
STEP PROCEDURE
1. MONITOR METER FUNCTION
Switch
RF to verify proper leveling of
internal Signal Generator on the
MONITOR Meter.
100% to verify or set 40%
modulation of each modulating tone
and set course centering on the
MONITOR Meter.
2. COUNTER MODE Switch
GEN to read out the Signal
Generator frequency on the DIGITAL
Display when operating in fixed
(FIXED) or variable (VAR) modes.
3. FREQUENCY MODE Switch
G/S FIXED is mandatory in ramp
operation and is used on bench for a
fixed channel center frequency.
G/S VAR to check all channel bench
operation. Set VAR FREQ Controls
to select the desired channel in
50 kHz steps.
4. CRYSTAL HI/LO Switch
(FREQUENCY MODE Switch set to
G/S FIXED
HI for 334.7 MHz RF output
LO for 329.6 MHz RF output.
5 TUNE Control
Adjust until TUNE Indicator stops
illuminating, indicating Signal
Generator is in the fine tune range.
STEP PROCEDURE
6. FINE TUNE switch
Press and adjust TUNE Control until
MONITOR Meter indicates least
deflection from left.
7. OUTPUT ATTENUATOR Control
Use as needed to establish Receiver
sensitivities.
8. RF OUT Connector
Connect to Receiver Antenna
Connector, or attach Antenna in
ramp operation.
9. G/S DDM Control
Use steps for precise amounts of
deflection and flag tests.
10. G/S VAR DDM Control
Use to check Auto-pilot Servos,
meter stickiness, etc.
11. MASTER MOD LEVEL Control
Set to CAL for 40% each course
tone or variable from 3% to 75%.
12. PWR/BAT Switch
PWR to use external ac line power
through the AC IN Connector.
BAT to initiate operation using
internal Battery power.
13. AVG/PEAK LOC XMTR Switch
(FREQUENCY MODE Switch set to
G/S FIXED)
PEAK LOC for simultaneous G/S and
LOC output.
