About AIS malfunction alarm
If the AIS transponder gets failed in operation, the AIS ABNORMAL status is supplied
from the transponder to the display causing the error message to appear on the
screen.
NOTE: In case no alarm signal lines are available in the AIS transponder, link the AIS
ALARM+ (Red dot/Pink wire) and AIS ALARM- (Black dot/Pink) signal lines at the
cable end at the transponder side. This processing is necessary to prevent the AIS
alarm message from being shown mistakenly on the display.
