receptor of indoor unit.
Note:
Use 2 LR03 AAA(1.5volt) batteries. Do not use rechargeable batteries. Replace batteries with new ones of the same type
when the display becomes dim.
CAUTIONS
For appropriate signal transmission between remote controller and
indoor unit, keep the signal receiver away from the following items:
 Direct sunlight or other strong lights or heat
 Flat panel television screen or other electrical appliances that react to
the remote controller
Additionally, the air conditioner will not operate if curtains, doors or
other materials block the signals from the remote controller to the indoor
unit. If the signal may not be transmitted properly, either move these
materials or consult your local dealer.
