Notes on batteries
• When replacing the batteries, use batteries of the same type, and replace both old batteries together.
• When the system is not used for a long time, take the batteries out.
• The batteries will last for approximately 1 year. If the remote controller display begins to
fade and the degradation of reception performance occurs within a year, however, replace
both batteries with new, size AAA.LR03 (alkaline).
• The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air conditioner.
■
Notes on remote controller
• Never expose the remote controller to direct sunlight.
• Dust on the signal transmitter or receiv e r will reduce the sensitivity. Wipe o ff dust with soft cloth.
• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such
as inverter-type lamps) is in the room. Consult the shop if that is the case.

Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
• Cover windows with a blind or a curtain.
Blocking sunlight and ai r from outdoors increases the cooling (heating) effect.
• Clogged air filters cause inefficient operation and waste energy.
Clean them once in about every two weeks.
■
Please note
• The air conditioner always consumes a small amount of electricity even while it is not operating.
•
If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker off.
