Troubleshooting
No Chart underlay
Check that you connected a positioning device(GPS) and heading device(compass),
and that both these external units are working correctly. Under normal conditions,
no red alarm indications should be visible on the right hand side of the screen.
Also, check that charts/cells and chart/cell permits are correctly installed. When
you haven’t the correct licenses, no chart will come up.
There are no radar echoes visible
Check that the video signal from the radar is connected to the Tresco PC. Also,
check that the direct radar image gives a good picture (Gain OK ?).
Check that when you move the radar mouse, you see the cursor of the radar
moving over the PC screen.
Check that the echo visibility slider is in the right up-most position.
The R/O menu pane is not visible
Make sure that your looking at the PC-generated screen. Move the PC pointing
device (mouse or trackball) to the bottom of the screen. Your menu should come
up automatically.
As long as you stay with your pointing-device inside the menu area, the menu will
stay.
