Additional Information

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

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.
