Maintenance
Replacing the lithium battery of the
card remote commander
Under normal conditions, the battery 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 commander becomes shorter.
Replace the battery with a new CR2025 lithium
battery. Use of any other battery may present a
risk of fire or explosion.
Notes on the lithium battery
•Keep the lithium battery out of the reach of children.
Should the battery be swallowed, immediately
consult a doctor.
•Wipe the battery with a dry cloth to assure a good
contact.
•Be sure to observe the correct polarity when
installing the battery.
•Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
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 7)
and clean the connectors with a cotton swab. 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.
