Insert two R6 (size AA) batteries (supplied) by 
matching 3 and # on the batteries to the 
diagram inside the battery compartment of the 
remote control.

• Do not leave the remote control in an extremely hot 

or humid place.

• Do not use a new battery with old ones.
• Do not mix manganese batteries and other kinds of 

batteries.

• Do not expose the remote control sensor to direct 

sunlight or lighting apparatuses. Doing so may 
cause a malfunction.

• If you do not intend to use the remote control for an 

extended period of time, remove the batteries to 
avoid possible damage from battery leakage and 
corrosion.

• When you replace or remove the batteries, the 

remote control buttons may be reset to their default 
settings. If this happens, reassign the input buttons 
(page 61).

• When the receiver no longer responds to the 

remote control, replace all the batteries with new 
ones.
