Table 5.2.2 TROUBLE message
Message Description Work to be required
TROUBLE:
RFCON CPU ROM NG.
When detecting the error of CPU
ROM on RF CON/CPU board. This
error occurs when the self test is
started from the function menu or
by turning on the system.
TROUBLE:
RFCON CPU RAM NG.
When detecting the error of RAM
on RF CON/CPU board. This error
occurs when the self test is started
from the function menu or by
turning on the system.
Changes RF CON/CPU
board.
TROUBLE:
RFCON CPU EEPROM
NG.
When detecting the error of
EEPROM on RF CON/CPU board.
This error occurs when the writing
of ID, DNID, ENID and [F8]-1,
and [F8]-2 is started. And when the
self test is started from the function
menu.
1. Changes EEPROM.
2. Changes RF CON/CPU
board.
TROUBLE:
Synthesizer UNLOCK.
When detecting the unlock of the
PLL synthesizer circuit on RF
CON/CPU board.
Changes RF CON/CPU
board.
TROUBLE:

voltage abnormality.
When detecting the antenna
supplied voltage (Tx29V/Rx7V) is
not the ratings.
1. Checks the antenna
coaxial cable.
2. Changes the antenna unit.
3. Changes PWR board.
TROUBLE:
ALARM unit Fault.
When detecting the communication
error between IC-306 and RF
CON/CPU board.
1. Checks the wiring.
2. Changes IC-306.
3. Changes RF CON/CPU
board.
4. Changes TERM CPU
board.
TROUBLE:
DMC connection
abnormality.
When detecting the communication
error between DMC-5 and RF
CON/ CPU board.
1. Checks the wiring.
2. Checks DMC-5.
3. Changes RF CON/CPU
board.
4. Changes TERM CPU
board.
TROUBLE:
DISTRESS ALERT
UNIT Fault.
When detecting the communication
error between IC-305 and TERM
CPU board.
1. Checks the wiring.
2. Changes IC-305.
3. Changes RF CON/CPU
board.
4. Changes TERM CPU
board.
TROUBLE:
Carrier power level.
TX current could not be detected
by PWR board at transmission, that
is no transmission.
(
Actuality, no appears)
1. Changes IC-115.
2. Changes RF CON/CPU
board.
3. Changes PWR board.
