be heard from the indoor unit. If no sound is heard,
operate again.

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.
When the remote controller cannot
be used (emergency operation)
When the batteries of the remote controller run out or
the remote controller malfunctions, the emergency op-
eration can be done using the EMERGENCY OPERA-
