Maintenance Guidelines

Cleaning Your Monitor

CAUTION: Read and follow the

Safety Instructions

before cleaning the monitor.

WARNING: Before cleaning the monitor, unplug the monitor power cable from the electrical outlet.

For best practices, follow the instructions in the list below while unpacking, cleaning, or handling your monitor:

• To clean your touch screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the antistatic coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.

• Use a lightly-dampened, warm cloth to clean the monitor. Avoid using detergent of any kind as some detergents leave a milky film on the monitor.

• If you notice white powder when you unpack your monitor, wipe it off with a cloth.

• Handle your monitor with care as a darker-colored monitor may get scratched and show white scuff marks more than a lighter-colored monitor.

• To help maintain the best image quality on your monitor, use a dynamically changing screen saver and turn off your monitor when not in use.

WARNING: Before you begin any of the procedures in this section, follow the

Safety Instructions .

Self-Test

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

1.

Turn off both your computer and the monitor.

2.

Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove all Digital (white connector) and the Analog (blue connector) cables from the back of computer.

3.

Turn on the monitor.

The floating dialog box should appear on-screen (against a black background), if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains white. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.

NOTE: You can run the built-in diagnostics only when the video cable is unplugged and the monitor is in self-test mode .

To run the built-in diagnostics:

1.

Ensure that the screen is clean (no dust particles on the surface of the screen).

2.

Unplug the video cable(s) from the back of the computer or monitor. The monitor then goes into the self-test mode.
