Maintenance

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.
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 4) 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.
