Code Message Level Config Note Action
0203 PSU TEMP
WARNING
W – Temperature on the
PSU board is over the
warning limit.
Check airflow of fans and
ambient temperature
(see chapter 5.2).
Clear the ventilation
opening.
If this fails to eliminate
the fault, send the radio
to service.
0204 PSU TEMP ERROR E – Temperature is over the
error limit.
See PSU TEMP
WARNING
0401 RX DC BATTERY W W/N DC battery voltage on
X2 is missing or low.
Check whether the DC
voltage is properly
connected to X2.
Measure DC voltage (see
chapter 3.4.7.4.3).
If no DC voltage is
c
onnecte
d, an
appropriate configuration
must be performed (see
chapter 3.3).
If this
fails to eliminate
the fault, send
radio to
service.
0402 RX AC MAIN W W/N AC main voltage on X1
is missing or low.
Check whether the AC
voltage is properly
connected to X1.
Measure AC voltage (see
chapter 3.4.7.4.3).
If no AC voltage is
c
onnecte
d, an
appropriate configuration
must be performed (see
chapter 3.3).
If this
fails to eliminate
the fault, send
radio to
service.
0403 RX DC 28V VLT LOW W – DC voltage on the RX
module is less than
22 V.
Check the DC voltage on
X2 (see chapter
3.4.7.4.3).
0404 RX DC 28V
OVERVOLT
E – DC voltage 28 V on the
RX module is more
than 32 V.
Check the DC voltage on
X2; normally the voltage
there must never be
more than 32 V (this is
the final charging voltage
of the 28 V lead battery).
If this fails to eliminate
the fault, send the radio
to service.
0405 RX INT REF
UNLOCK
E – Internal reference
unlocks.
Send the radio to service.
