Early manifuctions can be prevented. Careful and regular cleaning can extend the amount of time in that way, you will
have a new one. Be sure to turn the power off and unplug the power cord before you begin any cleaning.
CLEANING THE SCREEN
Here's a great way to keep the dust off screen for a while. Wet soft cloth in a mixture of lukewarm water and a little fa-
bric softener or dish washing detergent. Wring the cloth until it’s almost dry, and then used it to wipe the screen.
Make sure the remained water is off the screen and then let it air-dry before you turn on your monitor.
CLEANING THE CABINET
To remove dirt or dust, wipe the cabinet with a soft dry cloth. Please be sure not to use a wet cloth.
EXTENDED ABSENCE
If you expect to leave your monitor dormant for a long time (such as a vacation), it’s a good idea to unplug the power
cord to it from lightning or power surges.
