Dry-cell 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 1year.
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 batteries of the remote controller run out or
the remote controller malfunctions, the emergency olP
eration can be done using the EMERGENCY OPERA-
TION switch.

-- Description of"AUTO RESTART FUNCTION"
• These units are equipped with an auto restart function. When the main power is turned on, the air conditioner wilt start
operation automatically in the same mode as the one set with the remote controller before the shutoff of the main power.
• If the unit was set to off with the remote controller before the shutoff of the main power, it will remain stopped even after
the main power is turned on.
• If the unit was in the emergency operation before the shutoff of the main power, it will start operation, when main power
comes on, in the same mode as the one set with the remote controller before the emergency operation.
• If the unit is operated in "1FEEL ..." mode before power failure, the operation is not stored in the memory. In "1FEEL ..."
mode, the operation is decided by the initial room temperature at (re)start.
• Since the air conditioner has been shipped from the factory with the COOL mode saved in the memory for auto restart
function, it starts cooling operation when the user turns on the main power for the first time after installation.
