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 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.
