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.
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 8) 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.
Replacing the lithium battery
Under normal conditions, batteries will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote/rotary commander becomes shorter.
Replace the new lithium battery. Use of any other
battery may present a risk of fire or explosion.
