5 Maintaining the monitor

Maintenance guidelines

●

Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those controls

that are covered in the operating instructions. If the monitor is not operating properly or has been

dropped or damaged, contact an authorized HP dealer, reseller, or service provider.

●

Use only a power source and connection appropriate for this monitor, as indicated on the label/back

plate of the monitor.

●

Turn the monitor o when not in use. You can substantially increase the life expectancy of the monitor

by using a screen saver program and turning o the monitor when not in use.

NOTE: Monitors with a “burned-in image” are not covered under the HP warranty.

●

Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or

covered. Never push objects of any kind into cabinet slots or other openings.

●

Keep the monitor in a well-ventilated area, away from excessive light, heat, or moisture.

●

When removing the monitor stand, you must lay the monitor facedown on a soft area to prevent it from

getting scratched, defaced, or broken.

Cleaning the monitor

Turn o the monitor and disconnect power from the computer by unplugging the power cord from the

AC outlet.

2. Dust the monitor by wiping the screen and the cabinet with a soft, clean antistatic cloth.

3. For more diicult cleaning situations, use a 50/50 mix of water and isopropyl alcohol.

CAUTION: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface. Never

spray the cleaner directly on the screen surface. It may run behind the bezel and damage the electronics.

CAUTION: Do not use cleaners that contain any petroleum-based materials such as benzene, thinner, or any

volatile substance to clean the monitor screen or cabinet. These chemicals may damage the monitor.

Shipping the monitor

Keep the original packing box in a storage area. You may need it later if you move or ship the monitor.
