18. TROUBLE SHOOTING
The GPS Chart Plotter does not turn On. The voltage or the polarity may not be correct.
Make sure that the correct voltage (10-35 volt dc) is present. Check also that the polarity
is correct.
The GPS Chart Plotter does not get a valid fix. The GPS WAAS Smart Antenna may not
be in a open sky position or the antenna cable may not be properly connected. Make sure
that no metal obstacle is placed around the antenna acting as a shield for the antenna and
disconnect and connect again the antenna cable to the GPS Chart Plotter. If, after 15
minutes, the GPS Chart Plotter does not get the fix, turn it Off and On again.
The GPS Chart Plotter does not turn Off. The GPS Chart Plotter may be in an
unpredictable status. If, after pressing [PWR] (for at least 3 seconds) the GPS Chart Plotter
does not turn Off, turn Off the voltage.
The GPS Chart Plotter screen becomes very dark after a long exposure to direct
sunlight. The internal temperature is very high. Control the contrast. Protect the GPS Chart
Plotter from direct sunlight.
The GPS Chart Plotter does not respond to any command. The GPS Chart Plotter may
be in an unpredictable status. Try to turn Off, and then turn On. If the problem persists, reset
the RAM or remove power from the battery.
The location of my fix is not shown correctly on the Chart page. This is usually caused
when C-MAP Geo-References a nautical chart. Contact Jeppesen Marine with the Latitude
& Longitude of your vessels position, the position where you think your vessels should be
and with details of the cartography areas, which can be seen by selecting the Chart page,
press [INFO], move the ShuttlePoint knob to
Data Source and press [ENT]. Write down
the “Compilation scale”, “Notice to mariners” and “Horizontal datum”. Next contact C-MAP
USA at 508/477-8010 and advise the problem.
After storing the Chart Plotter over the winter, It takes a long time to receive a fix.
This is usually caused by the internal rechargeable memory battery from becoming low
which could cause the Internal RAM memory to become corrupted. To solve this issue,
perform a RAM clear (refer to Section 19).
NOTE
After performing a RAM Clear all Marks, Routes and tracks will be erased. To back up these points
refer to Section 11 for details.
