Troubleshooting steps
In automatic mode, the air conditioner
will automatically change the fan's
speed.
When dry mode is selected, the air
conditioner automatically adjusts the fan
speed. (The fan speed can be selected
during "COOL", "FAN ONLY", and
"HEAT".)
Wait for the power to come back on.
Replace the batteries.
The air conditioner operation will stop up
to the set time.
Up to the set time, the air conditioner will
automatically start and the appropriate
indicator will go off.
Directly transmit the signal transmitter of
the remote controller to the infrared
signal receiver of the indoor unit, and
then press the ON/OFF button twice.
