What to do if NMEA input signals are not listed in the NMEA input screen of my Skipper DL850?
If NMEA input signals are not listed in the NMEA input screen, it could be due to the wrong polarity of the input signals. Swap the NMEA input lines.
Why are there unrealistic aft speed values in docking mode on my Skipper DL850?
Unrealistic aft speed values in docking mode could be due to a wrong setup of ship parameters. Check the installation values for overall length and bow to sensor.
Why is there no echo gram contour on my Skipper DL850 Marine Equipment?
The absence of an echo gram contour indicates that the echo sounder is switched off. The echo sounder can be switched on in screen Diagnostics menu 3. It is not recommended to use if other echo sounders are in operation.
How to fix a picture that is difficult to read on Skipper DL850?
If the picture is difficult to read, it might be due to the screen contrast being too low or too high. Try increasing or decreasing the contrast setting. Another possibility is that the backlight is too weak, so try increasing the backlight setting.
Why is the display backlight malfunctioning on my Skipper DL850 Marine Equipment, but the display picture is visible?
If the display backlight is malfunctioning but the display picture is still visible, it may be due to defective backlight tubes. You should replace the tube assembly. Alternatively, the backlight power inverter could be defective, requiring you to replace the keyboard PCB.
