EElectromagnetic noise enters into TV sets or radios

No

Is the unit grounded?

Yes

Is the distance between the antennas and the indoor

unit within 9.91ft., or is the Yes distance between the

antennas and the outdoor unit within 9.91ft.?

No

Is the distance between the TV sets or radios and the

indoor unit within 3.28ft., or is Yes the distance between the TV

sets or radios and the outdoor unit within 9.91ft.?

No

Are the antennas damaged?

Is the coaxial cable damaged? Yes Is there any poor contact in

the antenna wiring?

No

Is the indoor/outdoor

Yes

connecting wire of the air conditioner and the wiring of the antennas close?

No

Ground the unit.

Extend the distance between the antennas and the indoor unit, and/or the antennas and the outdoor unit.

Extend the distance between the TV sets and/or radios and the indoor unit, or the TV sets or radios and the outdoor unit.

Replace or repair the antenna. Replace or repair the coaxial cable.

Extend the distance between the indoor/outdoor connecting wire of the air conditioner and the wiring of the antennas.

Even if all of the above conditions is fulfilled, the electromagnetic noise may enter, depending on the electric field strength or the installation condition (combination of specific conditions such as antennas or wiring).

Check the followings before asking for service. 1.Devices affected by the electromagnetic noise

TV sets, radios (FM/AM broadcast, shortwave)

2.Channel, frequency, broadcast station affected by the electromagnetic noise 3.Channel, frequency, broadcast station unaffected by the electromagnetic noise 4.Layout of ;

indoor/outdoor unit of the air conditioner, indoor/outdoor wiring, grounding wire, antennas, wiring from antennas, receiver

5.Electric field intensity of the broadcast station affected by the electromagnetic noise 6.Presence or absence of amplifier such as booster

7.Operation condition of air conditioner when the electromagnetic noise enters in.

1)Turn OFF the power supply once, and then turn ON the power supply. In this situation check for the electromagnetic noise.

2)Within 3 minutes after turning ON the power supply, press OPERATE/STOP (ON/OFF) button on the remote controller for power ON, and check for the electromagnetic noise.

3)After a short time (3 minutes later after turning ON), the outdoor unit starts running. During operation, check for the electromagnetic noise.

4)Press OPERATE/STOP (ON/OFF) button on the remote controller for power OFF, when the outdoor unit stops but the indoor/outdoor communication still runs on. In this situation check for the electromagnetic noise.

After checking the above, consult the service representative.
