Maintenance
Replacing the lithium battery of the 
remote commander
When the battery becomes weak, the range 
of the 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 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 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.
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.
