the breaker OFF. Then turn it ON again and try operating the air
conditioner with the remote control. If the lamp still flashes, call the
service shop where you bought the air conditioner.
• Are operation modes all the same for indoor units connected to outdoor

operation modes to “COOL” or “HEAT” for a moment and check again
that the lamps are normal. If the lamps stop flashing after the above
steps, there is no malfunction.
