POSSIBLE CAUSE
The fuse has blown.
No ACC position on vehicle
ignition.
The computer chip in the unit is
not functioning normally.
The unit is not connected to the
parking brake detection switch.
The parking brake is not
engaged.
The unit is in a location where
temperature is low.
The TV antenna and vehicle's
radio antenna are too close.
SOLUTION
After checking for short circuits
in the wires, replace the fuse
with one having the same rating.
Connect the same wire to the
ignition as the battery wire.
Press the reset button on the unit
(See page 3).
Make proper connections
according to "Connection" (See
page 15).
For safety reasons no video
picture are displayed while the
vehicle is moving. Engaging the
parking brake will cause picture
to be displayed.
If the temperature of the monitor
unit drops, the screen may
appear darker when power is first
turned on due to the
characteristics of a liquid crystal
panel. Wait a while after turning
power on for the temperature to
rise. Normal brightness will
return.
• Separate the two antennas as
far as possible.
• Turn off the LZ-701W.
