An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external

noise, and is likely to cause electromagnetic interference with nearby wireless devices.

A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these

effects may still occur. Please pay attention to the points listed below.

■ Noise malfunction

This refers to the application of high-frequency noise to the signal wires, resulting in abnormal signal pulses and malfunction.

Locations most susceptible to noise

1. Locations near broadcast stations where

there are strong electromagnetic waves

2. Locations near amateur radio (short wave)

stations

3. Locations near electronic sewing machines

and arc-welding machines

■ Electromagnetic interference

This refers to the noise generated by high-speed switching of the microcomputer and compressor. This noise radiates through

space and returns to electric wiring, affecting any wireless devices (televisions, radios, etc.) located nearby.

Locations most susceptible to noise

1. A television or radio is located near the

A/C and A/C wiring.

2. The antenna cable for a television or

radio is located close to the A/C and A/C

wiring.

3. Locations where television and radio

signals are weak.

Trouble

Either of the following trouble may occur.

1. The unit may stop suddenly during

operation.

2. Indicator lamps may flicker.

Trouble

1. Noise appears in the television picture,

or the picture is distorted.

2. Static occurs in the radio sound.

Correction

(The fundamental concept is to make the

system less susceptible to noise.)

— Insulate for noise or

distance from the noise source. —

1. Use shielded wires.

2. Move unit away from the noise source.

Correction

1. Select a separate power source.

2. Keep the A/C and A/C wiring at least 1 meter

away from wireless devices and antenna cables.

3. Change the wireless device's antenna to a high-

sensitivity antenna.

4. Change the antenna cable to a BS coaxial cable.

5. Use a noise filter (for the wireless device).

6. Use a signal booster.
