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 alkaline batteries
(size AAA).
•
Replace the 2 batteries with new batteries 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.
•
The service life of an alkaline battery is about 1
year.
However, since the recommended usable time limit
is indicated (month/year) on the bottom of the bat-
tery, a battery which the time limit is approaching
may be exhausted soon.
•
Dispose of exhausted batteries in the correct man-
ner.
