Major Alarms vs. Minor Alarms
Major Alarms (1-16)—report serious conditions that generally indicate
a hardware failure, or other abnormal condition that will prevent (or
seriously hamper) further operation of the transceiver. Major alarms
generally indicate the need for factory repair. Contact your Technical
Service representative for further assistance.
Minor Alarms (17-32)—report conditions that, under most circum-
stances, will not prevent transceiver operation. This includes out-of-tol-
erance conditions, baud rate mismatches, etc. The cause of these alarms
should be investigated and corrected to prevent system failure.
Event Code Definitions
Table 14 contains a listing of event codes that can be reported by the
transceiver. The codes shown are a subset of a larger pool of codes used
for various GE MDS products. For this reason, the table does not show
a sequential listing of all code numbers. Only the codes applicable to this
product are shown, and this list is subject to change with product revi-
sion.

Class Description
02 Major Frequency not programmed.
03 Major Authorization fault detected.
04 Major The RF synthesizer is reporting an out-of-lock
condition.
08 Major The system is reporting that it has not been
calibrated. Factory calibration is required for proper
radio operation.
09 Major DSP download fault.
12 Major Receiver time-out. No data received within the
specified receiver time-out time.
13 Major Transmitter time-out detected.
14 Major Alarm test.
16 Minor Unit address not programmed.
26 Minor The DC input voltage approaching an
out-of-tolerance condition. If the voltage is too far out
of tolerance, operation may fail.
29 Minor Output power not in valid range.
31 Minor The transceiver’s internal temperature is
approaching an out-of-tolerance condition. If the
temperature drifts outside of the recommended
operating range, system operation might fail.
37 Minor Unexpectedly executing APP 1.
38 Minor Unexpectedly executing APP 2.
39 Minor Boot error. Active image unknown.
42 Minor Reprogramming error.
