detection switch.

SOLUTION
After checking for short circuits in the
cables, replace the fuse with one having
the same rating.
Connect the same cable to the ignition as
the battery cable.
Press the reset button on the unit (see
page 4).

open while the vehicle is moving.
Engaging the parking brake.
Make proper connections according to
"Connections" (See page 32).
For safety reasons no television/ video
images are displayed while the vehicle is
moving. Engaging the parking brake will
cause images 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.
When the unit is set to auto dimmer, it is
not linked to the vehicle's light switch.
Make proper connections according to
"Connections" (See page 31).
