STEP 1
Setting the Remote Controller Signal Code
Use the following steps to select the signal code of the remote controller. (Note that the air con-
ditioner 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 applicable only to the signals in the

② Press the TIMER MODE button and check that the indoor unit can receive signals at the dis-
played signal code.
③ Press the MODE button to accept the signal code, and 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 controller resets to signal code A when the batteries in the remote controller 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 (
which operates the air conditioner.

SELECTING THE REMOTE CONTROLLER SIGNAL CODE
When two or more air conditioners are installed in a room and
the remote controller is operating an air conditioner other than
the one you wish to set, change the signal code of the remote
controller to operate only the air conditioner you wish to set (four
selections possible).
When two or more air conditioners are installed in a room,
please contact your retailer to set the individual air conditioner
signal codes.
• Confi rm the setting of the remote controller signal code and
the printed circuit board setting.
If these are not confi rmed, the remote controller cannot be
used to operate for the air conditioner.
Selecting the Remote Controller Signal Code
