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 4) 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.
