Chapter 2 OPERATING INSTRUCTIONS Front Panel Definition This Section defines the front panel User Interface for Led Indictor and Key function. Key Definition: There are five keys defined in this system and described bellows. External Controls Power on/off ?1 POWER Blue: power on Orange: in sleep mode ?2 OSD Function Press to view OSD. Press again to exit a selection in OSD. ?3 If OSD is active, press to select or adjust OSD options.
OSD Menu Picture Brightness: This adjusts the brightness of the picture on the screen. Contrast: This adjusts dark and light shades of color relative to each other to achieve a comfortable contrast. Color temp. : There are three ways of adjusting color: Warm (Reddish white) Cool (Bluish white) User : You can adjust the colors red, green and blue to the intensity you desire. Focus: This removes any horizontal distortion and makes the picture clear and sharp.
Option Auto Config. : System runs auto-configuration. Reset: Recall to default settings. Information: This shows brief information on the screen. Setting Language: Select the OSD menu language from English, French, German, Italian, Spanish, Simplified Chinese, Traditional Chinese, Japanese and Russian. OSD H. Position OSD V. Position OSD Time-out This changes the position of the OSD window on the screen and staying time.
LED Definition The system equips one dual color (blue/amber) led to indict system status and defined as bellows : LED Color System Status Blue System in normal operation mode Amber System in power-saving mode Dark System in power-off mode LOGO : When the monitor is power on, the LOGO will be showed in the center, and disappear slowly. HOW TO OPTIMIZE THE DOS-MODE Plug and play Plug & play DDC2B feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD.
THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL. IN ORDER FOR THIS MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO INPUT SIGNAL. This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) and/or the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK). This feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal present.
Chapter 3 Machine assembly This chapter contains step-by-step procedures on how to assemble the monitor for maintenance and trouble shooting NOTE : 1. The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding to avoid mismatch when putting back the components. 2. Note : The monitor surface is susceptible to scratching! Therefore, lay the monitor on a soft surface when mounting or removing the base. 3. Wear gloves.
