Additional Information
Precautions
If your car has been parked in direct sunlight, allow
the unit to cool off before operating it.
Moisture condensation
On a rainy day or in a very damp area, moisture
condensation may occur inside the display of the
unit. Should this occur, the unit will not operate
properly. In such a case, slide the POWER switch on
the bottom right of the unit to OFF position, then
wait for about an hour until the moisture has
evaporated.
Note on LCD panel
Some stationary blue, red or green dots may appear
on the monitor. These are called “bright spots,” and
can happen with any LCD. The LCD panel is
precision-manufactured with more than 99.99 % of
its segments functional. However, it is possible that
a small percentage (typically 0.01 %) of the
segments may not light up properly. This will not,
however, interfere with your viewing.
Maintenance
Fuse replacement
When replacing the fuse in the car battery adapter,
be sure to use one matching the amperage rating
stated on the original fuse. If the fuse blows, check
the power connection and replace the fuse. If the
fuse blows again after replacement, there may be an
internal malfunction. In such a case, consult your
nearest Sony dealer.
Warning
Never use a fuse with an amperage rating exceeding
the one supplied with the unit as this could damage
the unit.
