Cleaning the monitor

1. Turn o the monitor and unplug 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.

IMPORTANT: 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.

IMPORTANT: 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.

Entering user modes

The video controller signal may occasionally call for a mode that is not preset if:

●

You are not using a standard graphics adapter.

●

You are not using a preset mode.

If this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen display.
Your changes can be made to any or all of these modes and saved in memory. The monitor automatically
stores the new setting, and then recognizes the new mode just as it does a preset mode. In addition to the
factory preset modes, there are at least 10 user modes that can be entered and stored.

Power adapter

Manufacturer Model number Power supply rating

Delta ADP-120MH TF 19.5 V dc @ 6.15 A – 120 W

Energy saver feature

The monitor supports a reduced power state. The reduced power state will be entered into if the monitor
detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon detecting the
absence of these signals, the monitor screen is blanked, the backlight is turned o, and the power light turns
amber. When the monitor is in the reduced power state, the monitor will utilize <0.5 watts of power. There is
a brief warm-up period before the monitor will return to its normal operating state.

Refer to the computer manual for instructions on setting the energy saver mode (sometimes called power
management feature).

NOTE: The above power saver feature only works when the monitor is connected to a computer that has

energy saver features.

By selecting the settings in the monitor's Sleep Timer utility, you can also program the monitor to enter into
the reduced power state at a predetermined time. When the monitor's Sleep Timer utility causes the monitor
to enter the reduced power state, the power light blinks amber.
