Clean the air filters or take all obstacles away and turn the
breaker OFF. Then turn it ON again and try operating the air
conditioner with the remote controller. 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 units in the multi system?
If not, set all indoor units to the same operation mode and
confirm that the lamps flash.
Moreover, when the operation mode is in "AUTO", set all
indoor unit 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.

waves. Turn the breaker OFF, turn it ON again and try
operating the air conditioner with the remote controller.
