Possible cause and solution
This noise is caused by heat expansion or
contraction of plastics. It is no cause for concern.
The memory circuit of the microcomputer is
cleared. Operate the remote controller again to
restart the operation.
Remote control signals may not be received when
the signal receiver on the air conditioner body is
exposed to direct sunlight or strong lighting. In
that case, close curtains or shutters or switch off
or dim the light source.
If the unit is operated for a long period of time in a
high humidity environment, moisture may form on
the air outlet grilles and drip down.
