Maintenance

Replacing the lithium battery of the
remote commander
Under normal conditions, the battery 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 remote commander becomes shorter.
CAUTION
Danger of explosion if battery is incorrectly
replaced. Replaced only with the same or
equivalent type.
Notes on the 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 ensure 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.
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. 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.
