In case a failure occurs during operation, the radio displays a fault message. Refer to Table 9 and
perform the corrective actions listed for the corresponding message.
Table 9 . Fault Messages
Message Corrective Actions
NO CLOCK CHECK
•
That a 30A fuse is installed in the fuse holder located on the red wire of the power
cable.
• Check for good connection of power cable to the power supply and to the radio. If
connections and cable are OK, then the problem is in the LORD board
SYN FAIL Perform the built-in test using the MRC or RSS, to obtain more information.
PW_LATCH Perform the built-in test using the MRC or RSS, to obtain more information.
Check the condition of the antenna and its connections, because this error is displayed
when the VSWR exceeds 3.5:1. To check whether the problem is caused by high
VSWR, transmit into a dummy load. If the problem persists, there is a problem in the
HIGH POWER board
OVER TMP CHECK
•
That there is no obstruction to free air flow around the radio.
•
That the fan system is working and there are no obstructions to the fan
•
Perform the built-in test using the MRC or RSS, to obtain more information. If no
further information is displayed, the problem is in the HIGH POWER board
CU-LIMIT CHECK
• That the radio is programmed to TUNER OFF when your antenna system is not
equipped with an ATU.
•
For short-circuit or other damage to the antenna feed coax.
• That the ATU is in good working condition.
NOT PROG
(displayed when the
radio DC power
failed during
programming)
• The radio is not programmed and the baud rate is 1200 bps.
•
Program the radio parameters (using the MRC or RSS). This forces the radio to
accept the downloaded parameters
BATTERY FAIL
ERROR 11
The radio has an internal battery, that enables the memory to store the last channel
information that was used before the radio was turned off. If this battery becomes weak,
it will display this warning. When the battery is dead, all the channel information will be
retained, but the radio will always use channel 1 when you turn the radio on. (Example:
if you are scanning in the ALE mode and you turn the radio off; when you turn the radio
back on, it will be on channel 1)
DATABASE FAIL
ERROR 15 This message will display if the ALE scanned channels don’t match the programmed
channels in the RSS. (Example: ALE is programmed to scan channels 1, 2 and 3, but the
MRC or RSS program does not have a frequency programmed into channel 3)
