Overheat Indicator/Buzzer
The overheat indicator turns on and
the buzzer sounds when the engine
cooling circuit is faulty. The engine
speed slows down this time.
If using a panel-mount or top-mount
switch panel without indicators,
check the indicators displayed on an
NMEA2000-compatible device.
For information about NMEA2000-
compatible device displays, refer to
the display device's manual.
