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.
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 commander becomes shorter. Replace the battery with a new CR2025 lithium battery.

Fuse (10 A)

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 9) and clean the connectors with a cotton swab dipped in alcohol. Do not apply too much force. Otherwise, the connectors may be damaged.

Notes on 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. WARNING Battery may explode if mistreated.
