(Note that the air conditioner cannot receive a signal code if 

the air conditioner has not been set for the signal code.)

The signal codes that are set through this process are ap-

proceed to STEP 2.

The air conditioner signal code is set to A prior to shipment.

Contact your retailer to change the signal code.
The remote control unit resets to signal code A when the 

batteries in the remote control unit are replaced. If you use a 

signal code other than signal code A, reset the signal code 

after replacing the batteries.

If you do not know the air conditioner signal code setting, 

try each of the signal codes (

) until you find the 

code which operates the air conditioner.

NOTE:

Never mix new and used batteries, or batteries of different

Batteries should last about one year under normal use. If 

• 

the Remote Control Unit’s operating range becomes appre-

ciably reduced, replace the batteries and press the RESET 

button with the tip of a ballpoint pen or other small object.

7.2. Remote control unit holder installation

• 

from the remote control unit, then install the remote 

control unit holder.
Select the remote control unit holder selection site by 

• 

paying careful attention to the following: Avoid places in 

direct sunlight. Select a place that will not be affected by 

the heat from a stove, etc.

Install the remote control unit with a distance of 7 m  

• 

between the remote control unit and the photocell as the 

criteria. However, when installing the remote control unit, 

check that it operates positively.

Install the remote control unit holder to a wall, pillar, etc., 

• 

with the tapping screw.

Mount the holder.
