If no buttons are pressed within 30 seconds after the signal code is displayed, the system returns to the original clock
display. In this case, start again from step 1.
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 (

code which operates the air conditioner.
