Why is user setup and calibration data lost on my Skipper DL850?
If user setup and calibration data is being lost, it could be because the battery backup is not enabled. See “Back-up Battery Jumper JP200” on page 39 for details. It could also be due to a faulty battery. Replace the battery or I/O board.
Why is bottom tracking intermittent or erroneous on Skipper Boating Equipment?
Intermittent or erroneous bottom tracking can occur due to marginal gain or power settings, weather conditions, or a faulty transducer installation. Adjust the gain and power settings. Also, check the transducer wiring.
What to do if panel buttons malfunction on Skipper Marine Equipment?
If the panel buttons are malfunctioning, it could be due to defective buttons or interface. Replace the keyboard PCB or I/O PCB. It could also be that one button is stuck. Check the key switch(es) or replace the keyboard PCB. Finally, it could be a software problem, so recycle power or do a 'factory reset'.
Why is there no echo gram contour on Skipper Boating Equipment?
If there is no echo gram contour, the echo sounder may be switched off or the gain/TVG or power settings may be too low. Echo sounder can be switched on in screen pilot. Increase the gain/TVG and/or power settings.
What to do if the display backlight malfunctions on Skipper Boating Equipment?
If the display backlight malfunctions, turn off the power and wait for 5 seconds before restarting. If the issue persists, the backlight tubes or the backlight inverter PCB might be defective and need replacement.
What causes unrealistic aft speed values in docking mode on Skipper Boating Equipment?
Unrealistic aft speed values in docking mode are caused by a wrong setup of ship parameters. Check installation values for overall length and bow to sensor.
What to do if NMEA input signals are listed but not accepted by the DL850 Skipper Boating Equipment?
If NMEA input signals are listed but not accepted by the DL850, cycle the DL850 power or do a 'factory reset' after the NMEA connection is established. Also, check the remote (talker) setup.
Why is the bottom tracking intermittent or erroneous on my Skipper Marine Equipment?
Intermittent or erroneous bottom tracking could be due to marginal gain or power settings. Try adjusting these settings. Weather conditions can also affect bottom tracking, so try adjusting gain and power settings accordingly. A faulty transducer installation could also be the cause. Check the transducer wiring.
What does it mean when my Skipper Marine Equipment status screen shows Handshake (HSIN HSOUT) and the LEDs on the power and transmitter PCBs inside the transceiver cabinet never turn on?
If the status screen shows 'Handshake (HSIN HSOUT)' and the LEDs on the power and transmitter PCBs inside the transceiver cabinet never turn on, it could mean the transceiver unit power is off. Switch on the power in the transceiver unit or check the fuses. It could also indicate that a pair HSOUTA/HSOUTB on the display side or HSINA/HSINB on the transceiver side is not connected properly to the terminals or the polarity of the connection is wrong. Check the connection and polarity of the handshake lines. Finally, the communication cable might be damaged. Test or replace the cable.
How to fix a malfunctioning display backlight on Skipper DL850?
If the display backlight is malfunctioning and the display picture is hardly visible, try the following: 1. Turn off the power and wait for 5 seconds before restarting the device, as this could be due to DL850 initialization issues. 2. The backlight tubes could be defective and need replacement. 3. The backlight inverter PCB might be defective, requiring replacement.
