Event Code Definitions
Table 4 contains a listing of event codes that may 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 appli-
cable to this product are shown.
Internal Spectrum Analyzer
The radio contains a built-in spectrum analyzer tool that can be dis-
played on a connected PC. This utility is helpful in diagnosing inter-
ference problems, or for use during initial setup of the radio.

Description
01 Major Improper software detected for this radio model.
04 Major One or both of the internal programmable
synthesizer loops 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.
12 Major Receiver time-out. No data received within the
specified receiver time-out time.
17 Minor A data parity fault has been detected on the COM2
INTERFACE connector. This usually indicates a
parity setting mismatch between the radio and the
RTU.
18 Minor A data framing error has been detected on the
COM2 INTERFACE connector. This may indicate a
baud rate mismatch between the radio and the RTU.
26 Minor The DC input voltage is out-of-tolerance. If the
voltage is too far out of tolerance, operation may fail.
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 may fail.
