4.4.5 Maintenance
4.4.5.1 Cleaning Wireless Remote Control Switch
• Wipe it by soft, dry cloth.
• Do not use wet cloth to clean. It may cause failure of wireless remote control switch.
• Do not use benzine, thinner or detergent (Surfactant). If it is used, the wireless remote control switch may be deformed
or changed colour.
4.4.5.2 Replacing Batteries
Under the normal use, the battery life should be about 1 year (in case of alkaline batteries).
Replace the batteries if the following phenomenon is occurred:
The transmission distance between the remote control switch and the receiver kit gets shorter for operation or fan speed
adjustment
NOTE
Pay attention to the followings to use the batteries correctly. If not, it may cause liquid spill or burst.
• Never use the new and the used batteries together.
• Never use the different types of batteries (for example manganese battery and alkaline battery) together.
• When the wireless remote control switch is not used for a long time (more than 2 or 3 months), take out the batteries from the wireless
remote control switch.
The batteries attached are for validation. Therefore, the battery life may get shorter.
When the batteries are replaced, wait for more than 5 seconds to replace new.
All settings are reset after the batteries are replaced. Therefore, when “Identifying of Indoor Units Installed Side by Side” is set, this set-
ting is cancelled once the batteries are replaced. After replacing the batteries, set the “Identifying of Indoor Units Installed Side by Side”
again. (Press and hold “ON TIMER” and “OFF TIMER” simultaneously for 3 seconds. The indication “b” will appear. The details should
be referred to the installation manual.)
