Major Alarms vs. Minor Alarms
Major Alarms—report serious conditions that generally indicate a
hardware failure, or other abnormal conditions that prevent (or seriously
degrade) further operation of the transceiver. Major alarms generally
indicate the need for factory repair. Contact MDS for further assistance.
Minor Alarms—report conditions that, under most circumstances do
not prevent transceiver operation. These include out-of-tolerance
conditions, baud rate mismatches, etc. The cause of these alarms should
be investigated and corrected to prevent possible system failure.
Event Code Definitions
Table 6 contains a listing of the event codes that may be reported by the
transceiver.

Class Description STATUS Message
00 0000 0000 -- No alarms present. No Alarms Present
1–3 -- -- Not used. --
04 0800 0000 Major One or both of the internal programmable
synthesizer loops is reporting an out-of-lock
condition.
Synthesizer
Out-of-Lock
5–7 -- -- Not used. --
08 0080 0000 Major The system is reporting that it has not been
calibrated. Factory calibration is required for proper
radio operation.
Radio Not Calibrated
09 -- -- Not used. --
10 0020 0000 Major The internal microcontroller was unable to properly
program the system to the appropriate EEPROM
defaults. A hardware problem may exist.
EEPROM Write Failure
11 -- -- Not used. --
12 0008 0000 Major Receiver time-out. No data received within the
specified receiver time-out time.
Receiver time-out
13 0004 0000 Major Transmitter time-out. The radio was keyed for a
duration exceeding the time-out timer setting. (This
alarm clears the next time the radio keys.)
Transmitter time-out
14–16 -- -- Not used. --
17 0000 4000 Minor A data parity fault has been detected on the DATA
INTERFACE connector. This usually indicates a
parity setting mismatch between the radio and the
RTU.
Data Parity Error
18 0000 2000 Minor A data framing error has been detected on the
DATA INTERFACE connector. This may indicate a
baud rate mismatch between the radio and the
RTU.
Data Framing Error
19–30 -- -- Not used. --
