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 9) 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.
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
card remote commander becomes shorter.
Replace the battery with a new CR2025 lithium
battery. Use of any other battery may present a
risk of fire or explosion.
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.
• Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
