light which comes from fluorescent bulbs or neon signs may interfere with the
remote control.

does not operate.
• Check whether the
indicator is displayed at the bottom right of the
remote control display. In this case, turn off both the air conditioner and the
auxiliary power switch, and then contact a service centre.
The air conditioner is
not turned on or off
immediately with the
wired remote control.
• Check whether the wired remote control is set for group control. In this
case, the air conditioners connected to the wired remote control are turned
on or off sequentially. This operation takes up to 32 seconds.
The Timed on/off
