The following are not malfunctions:

• When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be colored. This is due to the structure of the cathode ray tube and will disappear when another image is displayed.

• You may sometimes experience a mild electric shock when you touch the picture tube. This phenomenon is due to a normal buildup of static electricity on the CRT and is not harmful.

• The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an abnormality appears on the screen as well.

• If two or more monitors are placed close each other, their images may shake or be distorted. This phenomenon is due to mutual interference; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn the power off on any monitor that is not being used.

7Self-check Indications

When the INPUT SELECT A/B and DC INDICATOR lamps on the front panel start flashing after the screen

goes blank...

This monitor has a self-check function, which allows it to detect malfunctions and alert you. This makes troubleshooting easier. Whenever a problem occurs, a combination of “self-check indicators” (INPUT SELECT A/B and DC INDICATOR lamps) will flash and the monitor’s power automatically turns off. If this happens, follow the steps below and contact your dealer to resolve the problem.

1. Check which indicators are flashing.

2. Turn off the AC or DC switch on the rear panel.

3. When using the AC power supply, unplug the AC power cord.

When using the DC power supply, remove the battery or unplug the DC power cord.

4. Contact your dealer with the information about which indicators are flashing.

NOTE:

•If you turn on the monitor’s power immediately after turning it off (or after a short-term power failure), the self-check indicators may flash, and no image may be displayed.

When this happens, turn off the power, and wait at least 10 seconds before turning it on again. If the self-check indicators have stopped flashing, you can use the monitor as usual.
