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 5) 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.
