•When a button is pressed, one or two beeps will be heard from the indoor unit. If no sound is heard, operate again.

•Use the remote controller carefully.

If it is dropped, thrown or it gets wet, the remote controller may not operate.

Reference for replacing batteries

When the indoor unit does not respond to the signal from the remote controller, or the display becomes dim, replace the batteries with new ones (size AAA).

•Though both alkaline batteries and manganese batteries can be used, alkaline batteries are rec- ommended because their service life is longer than that of manganese batteries.

•The service life of an alkaline battery is about 1 year. However, a battery which the time limit is ap- proaching may be exhausted soon. The recom- mended usable time limit is indicated (month/year) on the bottom of the battery.

•Replace the 2 batteries with new ones of the same type.

•Do not use rechargeable batteries.

•To prevent liquid leakage, take out all batteries when the remote controller is not going to be used for a long time.

•Dispose of exhausted batteries in the correct man- ner.
