4 Adjust R44 CCW until the meter slightly deflects downward.
5 Set R6 fully CW.
5.1.9 Monitor Control PWB
1 Turn RF LEVEL fully CCW.
2 Turn R2 on the MONITOR PWB fully CW. See Figure “Monitor PWB Diagram,” on
page 2-43. Switch MONITOR switch to RST and back to DSBL. Ensure the RF ON/OFF
switch is in the ON position.
3 Turn off all power sources. Disconnect dummy load. Re-apply power.
4 Place RF METER switch in REFL and set MODE switch to CONT.
5 Adjust RF LEVEL slowly CW for a 20% power reading.
6 Turn R2 on the MONITOR PWB slowly CCW until DS2 is fully illuminated.
7 Turn RF LEVEL fully CCW. Turn off all power sources. Reconnect the Dummy Load. Re-
apply power.
8 Turn R6 and R22 on the MONITOR PWB fully CCW.
9 Place RF METER switch in FRWD and MODE switch in CARR.
10 Adjust RF LEVEL to desired shutdown power.
11 Place the MODE switch in CONT. Adjust modulation to 70% or desired modulation shutdown
threshold. Place MODE switch in IDENT
12 Connect DC voltmeter to TP3 on the MONITOR PWB. Voltage should be approximately
1.5VDC.
13 Adjust R6 CW until meter deflects upwards to approximately 5.5V during IDENT.
14 Place MODE switch in CARR and adjust RF LEVEL to full rated power. Voltage at TB3
should indicate approximately 5.5VDC.
15 Place MODE switch in IDENT and adjust R22 CW until the meter deflects upward between
5.5 and at least 8V while identing. Return modulation to operating level (95%). Remove
voltmeter.
16 Check shutdown by placing MONITOR switch in RST, then ENBL and MODE switch in
CARR. Transmitter should shutdown after a time delay. Reset and place MODE switch in
CONT. Transmitter should shut down after a time delay. Reset, place MODE switch in
IDENT and reduce power to a level below the shutdown level. Transmitter should shutdown
after a time delay. Reset and readjust power to desired level. Transmitter should not
shutdown.
