Replacing Batteries

Remove the COVER from
the back of the remote
controller.

• Slide the cover
according to the arrow
direction

Insert two battaries.

• Be sure that the (+) and
(–) directions are correct

• Be sure that both batteries
are new

Re-attach the cover.

• Slide it back into position

• Do not use rechargeable batteries such batteries differ from standard dry cells in shape,

dimensions and performance.

• Remove the batteries from the remote controller if the air conditioner is not going to be used for
an extended length of time.
