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.

Entering user modes
Under the following conditions, the video controller signal may occasionally call for a mode that is not preset:
●
You are not using a standard graphics adapter.
●
You are not using a preset mode.
It 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.
Energy saver feature
The monitors support a reduced power state. The reduced power state will be initiated if the monitor detects
the absence of either the horizontal sync signal 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 returns to its normal operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called power
management features).
NOTE: The energy 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 Energy Saver utility, you can also program the monitor to initiate the
reduced power state at a predetermined time. When the monitor's Energy Saver utility causes the monitor to
initiate the reduced power state, the power light blinks amber.
