safety device may work to stop the operation of
the outdoor unit only.)

Description / what to check
• The batteries may be exhausted.
Replace both batteries with new dry batteries AAA.LR03 (alkaline).
For details, refer to "Preparation Before Operation".
• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such
as inverter-type lamps) is in the room. Consult your dealer if that is the case.
• The remote controller may not function correctly if the transmitter is exposed to direct sunlight.
• Is there a device in the room that redirects remote controller signals?
Some appliances such as TV speakers are equipped with these devices.
If there is such a device in the room, the signals it emits may interfere with signals from the
remote controller, preventing reception.
• Infrared rays from smartphones and game consoles may interfere with signals from the
remote controller, preventing reception.
• The batteries may be exhausted.
Replace both batteries with new dry batteries AAA.LR03 (alkaline).
For details, refer to "Preparation Before Operation".
• If the remote controller activates other electric devices, move them away or consult your
dealer.
Description / what to check
• The room odor absorbed in the unit is discharged with the airflow.
We recommend you to have the indoor unit cleaned. Please consult your dealer.
• The indoor unit is blowing out room odor it has absorbed (the smell of walls or carpeting,
furniture, clothes, and so on).
If the air conditioner has been used for a long time, there is a chance that a dirty heat
exchanger or fan are emitting an odor.
We recommend you to have the indoor unit cleaned. Please consult the dealer where you
bought the air conditioner.
Do not spray the air conditioner unit with any deodorizers.
Description / what to check
• The air conditioner may malfunction due to lightning or radio.
If the air conditioner malfunctions, turn off the power with the circuit breaker and restart the
operation with the remote controller.
• Slide the DIP switch to the left as shown in the
illustration so that the HEAT operation can be selected
with the "MODE" button.
• Check if the ON/OFF TIMER and the WEEKLY TIMER are set to the same time.
Change or deactivate the settings in the WEEKLY TIMER.
