PREPARATION BEFORE OPERATION
Handling of the remote controller
•
The range that the signal can reach is about 6 m when the remote controller is pointed at the front of the
indoor unit.
•
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.
When installing on a wall, etc.
•
Install the remote controller installation case in a position where the signal reception sound (beep) can be
ON/OFF
heard from the indoor unit when the button is pressed.

Dry-cell batteries
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 recommended
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 approaching may be exhausted soon. The recommended 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 manner.
