Maintenance

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.
