Maintenance
Cleaning
• Clean the surface of the suction cup with a soft,
wet lint-free cloth if it becomes dirty and
attachment strength weakens.
Be sure to dry the suction cup before
reattaching.
• Clean the display window with a commercially
available cleaning cloth.
Note
If the suction cup leaves a trace on the windshield,
wipe with water.
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
(2.5 A). 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.

Remove the built-in lithium-ion battery when
disposing of the unit, and return the battery to a
recycling location.
The procedure for removing the battery is

Note
Never disassemble the unit except when disposing of
