Inserting batteries into the

Insert two R6 (size-AA) batteries in the
RM-AAL002 remote commander.
Observe the correct polarity when installing
batteries.
Notes
• Do not leave the remote in an extremely hot or
humid place.
• Do not use a new battery with old ones.
• Do not mix alkaline batteries and other kinds of
batteries.
• Do not expose the remote sensor to direct sunlight
or lighting apparatuses. Doing so may cause a
malfunction.
• If you do not intend to use the remote for an
extended period of time, remove the batteries to
avoid possible damage from battery leakage and
corrosion.
Tip
Under normal conditions, the batteries should last
for about 3 months. When the remote no longer
operates the receiver, replace all the batteries with
new ones.
