LOW BATTERY DATA IS IN DANGER see S.6-2.
LOW AIRFLOW check if air intake (rear panel) and exhaust
(above tubes) openings are clear of obstruc-
tions; RD&T*
LOW GAIN RD&T*; check the coaxial cable from trans-
ceiver output to amplifier input.
MICROPROCESSOR CONFLICT OFF5*
MOTOR VOLTAGE TOO HIGH CMV*
MOTOR VOLTAGE TOO LOW check if the power transformer is properly
connected (see S.2-3) ; CMV*
QSK BREAK in FAULT OFF5*; CCC*
PROCESSOR CONFLICT
REAR TUBE EXHAUST TEMP TOO HIGH check if air intake (rear panel) and exhaust
(above tubes) openings are clear of obstruc-
tions; RD&T*;
REFLECTED POWER TOO HIGH check antenna cable, selector, antenna and
grounding for loose contacts or worsened in-
sulation; trim the antenna for minimum VSWR
or use an antenna tuner; try another antenna;
check if REFLECTED POWER is induced from
another nearby transmitter.
REMOVE AND REDUCE DRIVE POWER RD&T*
RF PLATE =......V SHOULD BE ZERO OFF5*; CCC*
RF GRID =......W SHOULD BE ZERO OFF5*; CCC*

TUNE CAPACITOR SYSTEM MALFUNCTION OFF5*
+5V TOO HIGH (TOO LOW) CMV*
+/- 12V TOO HIGH (TOO LOW) CMV*
+24V /+48V TOO HIGH (TOO LOW) CMV*
* Abbreviations:
OFF5 - Turn amplifier off for 5 minutes and try again.
RD&T - Reduce drive power from transceiver; do AUTO TUNE - see S.4-1.
CMV - Check the mains voltage and its conformity with the voltage selector - see S.2-2 and
table 2-1.
CCC - Check the control cable from the transceiver to the KEY-IN input - see S.2-4.
