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.
Cleaning the front panel display
Wipe dust or dirt from the front panel surface
with the supplied cleaning cloth.
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
rotary commander becomes shorter. Replace the
battery with a new CR2032 lithium battery. Use
of any other battery may present a risk of fire or
explosion.
1 Opening the battery compartment lid

battery compartment lid by rotating
anticlockwise with a coin.
2 Removing the battery
Press the side of the battery as illustrated,
then remove.
3 Inserting the battery
Insert the battery as illustrated. Make sure the
polarity of the battery is oriented in the
correct way.
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.
