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.
WARNING
Battery may explode if mistreated.
Do not recharge, disassemble, or dispose
of in fire.
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 4) and clean the
connectors with a cotton swab. Do not apply
too much force. Otherwise, the connectors
may be damaged.
