of the remote commander becomes shorter.
Replace the battery with a new CR2025

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 7) and clean the
connectors with a cotton swab. Do not apply
