Notes on battery use
To avoid damage from battery leakage
and corrosion:
— Make sure the polarity of the
batteries match the + and – markings
in the battery compartment.
— Do not use an old battery with a new
one, or different types of batteries
together.
— Remove the batteries when the
system will not be used for a long
period of time.
— Do not charge the batteries.
If any battery leakage occurs, replace
both batteries after cleaning the battery
compartment.
Notes on the wireless remote
GB
•To prevent deformation due to heat, do
not leave the remote in a place subject
to direct sunlight.
•Direct sunlight may affect the system's
ability to receive infrared signals from
the remote. If this happens, move the
remote closer to the remote control
sensor of the system.
•When parking your car, put the remote
somewhere, such as the glove
compartment, that is away from direct
sunlight to prevent deformation due to
heat.

Fuse replacement
When replacing the fuse, be sure to use
one that matches the amperage
described on the 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
