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 in-
door unit.
• When a button is pressed, one or two beeps will be
heard from the indoor unit. If no sound is heard, op-
erate again.
• Use the remote controller carefully.
If it is dropped, thrown or it gets wet, the remote con-
troller may not operate.
When installing on a wall, etc.
• Install the remote controller installation case in a po-
sition where the signal reception sound (beep) can

I Reference for replacing batteries
When the indoor unit does not respond to the signal from
the remote controller, or the display becomes dim, re-
place the batteries with new ones (size AAA).
• Though both alkaline batteries and manganese bat-
teries can be used, alkaline batteries are recom-
mended 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 approach-
ing may be exhausted soon. The recommended us-
able time limit is indicated (month/year) on the bot-
tom 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.

ERATION)
