The monitor makes a sound
when it is turned on.
This is normal as some sound may be generated when the metal
case and the electromagnet, which are installed to block any
electromagnetic waves, interact with each other.
How can I clean the outer
case/Picture tube?
Disconnect the power cord and then clean the monitor with a soft
cloth, using either a cleaning solution or plain water.
Do not leave any remains of the detergent nor scratch the case.
Do not allow any water to go inside the monitor.

Useful Tips
Your monitor provides a self test feature that allows you to check whether your monitor is
functioning properly.
Self-Test Feature Check
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a box in the illustration below.
This box appears during normal operation if the video cable becomes disconnected or
damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the
monitor.
If your monitor screen remains blank after using the previous procedure, check your video
controller and computer system; your monitor is functioning properly.
Warning Messages
If there is something wrong with the input signal, the message below appears on the screen
or the screen goes blank although the power indicator LED is still on. The message may
indicate that the monitor is out of scan range or that you need to check the signal cable.
Environment
The location and the position of the monitor may influence the quality and other
features of the monitor.
1. If there are any sub woofer speakers near the monitor, unplug and relocate the woofer
to another room.
2. Remove all electronic devices such as radios, fans, clocks and telephones that are
within 3 feet (one meter) of the monitor.
