3. OPERATING INSTRUCTIONS

3.1 GENERAL INSTRUCTIONS

Press the power button to turn the monitor on or off. The other control buttons are located at front panel of the monitor. By changing these settings, the picture can be adjusted to your personal preferences.

-The power cord should be connected.

-Connect the video cable from the monitor to the video card.

-Press the power button to turn on the monitor, the power indicator will light up.

3.2ADJUSTING THE PICTURE

I.

Analog-Only Model

II. Dual-Input Model, Analog Signal Input

III. Dual-Input Model, Digital Signal Input

Note: There is a difference of the LM929 and EN9250: LM929’ s LOGO is “AOC” and EN9250’s LOGO is “ENVISION”

4.3 DIGITAL CONTROL OPERATION

Signals used for mode detection:

-Nominal horizontal frequency

-Nominal vertical frequency

-Horizontal sync. Pulse polarity

-Vertical sync. Pulse polarity

The tolerance for detecting the horizontal frequency is between ±1KHz from center frequency The tolerance for detecting the vertical frequency is between ±0.5hz from center frequency

FACTORY PRE-SET MODES FOR ANALOG INPUT

Starting the “ RESET” function in the OSD-MENU will clear all old settings of auto configuration in preset modes & OSD back to center & Language set to English

FACTORY PRE-SET MODES FOR DIGITAL INPUT

Starting the “ RESET” function in the OSD-MENU will auto-centering the Image& OSD back to center & Language set to English

PROTECTION CIRCUIT

Missing or improper sync pulses will not damage the monitor. Additionally, under these conditions, the monitor shall not cause damage to the driving source
