Fuse replacement

When replacing the fuse, 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.

Cleaning the connectors

The unit may not function properly if the
connectors between the unit and the front panel
are not clean. In order to prevent this, detach the
front panel (page 7) and clean the connectors
with a cotton swab dipped in alcohol. Do not
apply too much force. Otherwise, the connectors
may be damaged.

Notes
• For safety, turn off the ignition before cleaning the

connectors, and remove the key from the ignition
switch.

• Never touch the connectors directly with your fingers

or with any metal device.
