18. Notice 9018: (ADE) Low RSSI level.
The status for this error is confirmed during selftest. This message will be output
when the LNA Module output is too low. Please replace the Front end Module
(ATB/LNA assembly)
Note) If the Antenna is operating in a normal manner, the error may be a false
detection.
19. Notice 9019: (ADE) Microcontroller temperature low.
The status for this error is constantly confirmed at an interval of 3 seconds. This
message will be output when the temperature for the ATB Module CPU is too low. It
implies a failure in the ATB Module. Please replace the Front end Module (ATB/LNA
assembly)
Note) If the Antenna is operating in a normal manner, the error may be a false
detection.
20. Notice 9020: (ADE) Microcontroller temperature high.
The status for this error is constantly confirmed at an interval of 3 seconds. This
message will be output when the temperature for the ATB Module CPU is too high.
Please replace the Front end Module (ATB/LNA assembly)
Note) If the Antenna is operating in a normal manner, the error may be a false
detection.
21. Notice 9021: (ADE) Heater fault.
The status for this error is confirmed during selftest. This message will be output
when there is an abnormality for the heater of the HPA Module. It implies a failure in
the HPA Module.
Note) If the Antenna is operating in a normal manner, the error may be a false
detection.
22. Notice 9022: (ADE) Flash data corrupted.
The status for this error is constantly confirmed at an interval of 3 seconds. This
message will be displayed when a Flash ROM error is detected in the ATB Module.
Please replace the Front end Module (ATB/LNA assembly)
Note) If the Antenna is operating in a normal manner, the error may be a false
detection.
23. Notice 9023: (ADE) ASK fault.
The status for this error is constantly confirmed at an interval of 1 second. This
message will be output when communication abnormality (timeout) is detected in
between ADE and BDE. It implies a failure in the MODEM board or the IF board in
the ATB Module, Interface Module, or the Communication unit.
If the case is a failure for the ATB Module, replace the Front end Module (ATB/LNA
assembly).
Note) There are some cases that this error would occur temporarily; if the error
occurs on a constant basis, it will need to be corresponded.
