6. TROUBLESHOOTING
6.1 NO POWER
1. Make sure the system wire is connected to the main wire coming from the monitor, and
also double check if the plug is inserted properly.
2. Make sure the system wire harness and especially the black and red wires (for current
supply) are connected to the on board voltage system of the vehicle. The red wire is
for +12V, the black wire goes to GND. Wrong polarity connection of these two wires may
damage the unit!
6.2 NO FUNCTION OF REMOTE CONTROL
1. Make sure the battery is in good condition and inserted the right way.
2. Make sure to aim the remote control at the IR-receiver eye, and there are no obstacles in
between.
3. Note, that if the remote control is operated too far away from the IR-receiver eye, the IR-sig-
nal becomes too weak. The normal operating distance between monitor and remote control
should be kept below 7 meters.
6.3 NO DISPLAY OR UNCLEAR PICTURE
1. Check the video signal wires first, and make sure they are connected properly.
2. Make sure the AV input in the menu /AV1 / AV2 / AV3) has been chosen and set according
to the video signal input connected to the system wire harness.
3. Check the antenna or adjust it, to improve signal strength of the tuner connected to the
monitor.
4. Make sure the monitor is in proper position with viewing position as directly on-axis as
possible.
