Maintenance and Fault Finding
Boat Speed reads 0
Information being transmitted from the Hull Transmitter is being received
with a zero value. Check the paddle wheel for fouling, clean it and make
sure it turns easily.
Wind Speed reads 0
Information being transmitted from the Wind Transmitter is being
received with a zero value. If the anemometer cups at the top of the mast
are turning and the wind speed reads zero then there is a problem with
your Wind Transmitter.
No NMEA data showing on external displays
Enter Setup mode on the remote display and scroll to the Health
Chapter. Check the signal level and battery status of the Wireless
(NMEA) Interface. If the signal level shows a value greater than 3 then
check the data connections and the settings of the NMEA equipment to
ensure that NMEA 0183 is being transmitted correctly.
The Depth Alarm does not sound
If the actual water depth is shallow and the alarm has not sounded it is
most likely that the alarm is switched off. Enter Setup mode on the
Remote Display and scroll to the Depth Chapter. Ensure the Depth
Alarm settings are correct.
Compass information displayed on the system does not agree
with the main steering compass.
Ensure that the main steering compass has been swung correctly and
is showing correct information. Ensure that the Compass Calibration
procedure has been correctly completed (see the Remote Display user
guide). If there are still differences, look for magnetic objects (loud
speakers, pumps and motors, etc.) close to the Compass Transducer
and try mounting the transducer in an alternative location. After
changing position of nearby equipment or the Compass Transducer it
will be necessary to re-calibrate the compass.
