16. 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. Pressing [PWR] (for at least 3 seconds) the GPS
Chart Plotter does not turn Off, turn Off the voltage. Perform RAM clear. Refer to section
17.0.0 RAM Menu (reset).
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. Try to turn Off, and then turn
On. If the problem persists, reset the RAM (refer to section 17.0.0 RAM Menu (reset)) 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 C-MAP 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 17).
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.
