Message Corrective Actions
OVER TMP Check that there is no obstruction to free air flow around the radio.
When using the cooling tray, check that the fan is working and there are no
obstructions to fan rotation.
Perform the built-in test using the MRC, to obtain more information. If no further
information is displayed, service the Micom-Z unit (defective HIGH POWER
board)
CU-LIMIT Check that the radio is programmed to TUNER OFF when it is not equipped with
an ATU, or does not use the FAD1410 antenna system.
Check for short-circuit or other damage to the antenna feed coax.
Check that the ATU is in good working condition
NOT PROG
(Error 14)
This message indicates that the radio is not programmed (the message may
also appear if the radio DC power failed during programming). In this case, the
default baud rate of the MRC interface is 1200 bps.
Program the radio parameters (using the MRC). This forces the radio to accept
the downloaded parameters
BATTERY FAIL
(Error 11)
Micom-Z 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).
You may continue using the radio, but request service as soon as possible
DATABASE FAIL
(Error 15)
This message will appear if the ALE scanned channels do not match the
programmed channels in the MRC (for example, ALE is programmed to scan
channels 1, 2 and 3, but the MRC program does not have a frequency
programmed into channel 3).
Check and correct the programmed parameters
3-7.2.3 Interpreting BIT Results and Error Codes
Micom-Z performs self-test whenever it is turned on, and also upon operator’s command, as explained
below.
If a problem is detected, you will see a two-digit error code. Most of the codes indicate a hardware
problem, and therefore, in general, you should request service for Micom-Z unit (contact your service
representative and report the malfunction or error code).
1. Turn the radio set off, and then turn it back on, and monitor the display: every time the radio is
turned on, a self-test procedure is performed. If an internal malfunction is found, an error
message will be displayed. Refer to Table 3-3 for a description of the error codes, and the
recommended actions.
2. Activate the BIT function, using MENU > BIT. You have three options:
• FULL (F1) – runs a full test of the Micom-Z.
• CHAN (F2) – tests Micom-Z operation on the current channel.
• L.RF (F3) – tests the Micom-Z receive path only.
