This document describes the Acer LCD Monitor, a device designed for visual display with user-friendly controls and a focus on comfortable viewing.

Function Description:

The Acer LCD Monitor serves as a visual output device for computers, displaying graphics and text. It features an On-Screen Display (OSD) menu for easy adjustment of various display parameters.

Usage Features:

Installation:
- Unpacking: Before setup, a stable and clean workspace near a wall power outlet is recommended. Ensure sufficient airflow around the monitor. The package includes the LCD Monitor, AC Adapter, 1.5M Monitor-to-PC signal Cable, 1.8M Power Cord, Base, and User's Manual.
- Connecting the LCD Monitor and Base: The base should be placed on the desk first, then the LCD Monitor is connected to the base (refer to Figure 1-1).
- Viewing Angle Adjustment: The monitor allows for a comfortable viewing angle, adjustable from -5° to +35° (refer to Figure 1-2). Users are warned not to force the monitor beyond these limits to prevent damage.
- Detaching LCD Monitor from Its Stand: To detach, unscrew the hinge bracket screws and remove the stand from the LCD monitor (refer to Figure 1-3).
- Interface for Arm Applications: The rear of the display has four integrated 4 mm, 0.7 pitches threaded nuts and four 5 mm access holes, meeting VESA Flat Panel Monitor Physical Mounting Interface Standard specifications (paragraphs 2.1 and 2.1.3, version 1, dated 13 November 1997) (refer to Figure 1-4).
- Connecting to Computer: Power off the computer. Connect one end of the signal cable to the LCD Monitor's VGA port and the other end to the PC's VGA port. Ensure all connections are secure (refer to Figure 1-5). An off-the-shelf video cable with a ferrite-core interface is required for FCC compliance.
- Connecting AC Power: Connect the power cord to the AC adapter, then the AC adapter's DC output connector to the monitor's DC Power Jack, and finally the power cord to an AC power source (refer to Figure 1-6). It is recommended to use a "Surge Protector" device to prevent damage from power surges.
- Setting Up: Ensure the AC Adapter is connected and turn on the LCD Monitor's power switch on the bezel.

If an unsupported timing is selected, the monitor will use the most suitable available timing.

Maintenance Features:

Cleaning: To clean the LCD Monitor screen, power off the monitor and unplug the AC Cord. Spray a non-solvent cleaning solution onto a rag and gently clean the screen.
Storage: Store the LCD Monitor in a room with a temperature of -20° ~ 60°C (-4° ~ 140°F). Storing outside this range could result in permanent damage.
Troubleshooting:
- Unclear/Unstable Picture: If the picture is unclear or unstable, enter "Shut Down Windows" status. Check for black vertical stripes; if present, adjust the "Clock" function in the OSD menu. Then, adjust the "Phase" function for the clearest display. Return to normal PC operation.
- No Picture:
  - Ensure power indicator is ON, all connections are secure, and the system is running on the correct timing (refer to Chapter 3 for timing information).
  - Turn off and on the LCD Monitor. If still no picture, press the Adjustment Control button several times.
  - If the above steps fail, connect the PC to an external CRT. If the PC functions properly with the CRT but not the LCD Monitor, the VGA card's output timing may be out of the LCD's synchronous range. Change to an alternative mode listed in the Standard Timing Table or replace the VGA card.
  - If an output timing outside the monitor's synchronous range (Horizontal: 24 ~ 61 KHz, Vertical: 56 ~ 75 Hz) is chosen, the OSD will display "Out of Range." Select a supported mode.
  - If the signal cable is not connected or improperly connected, the monitor screen will display "No Input Signal."
Safety:
- Do not place the monitor near a window to avoid rain, moisture, or sunlight damage.
- Do not apply pressure to the LCD screen to prevent permanent damage.
- Do not remove the cover or attempt to service the unit yourself; servicing should be performed by an authorized technician.
- Immediately unplug the monitor and call an authorized technician if the signal cable is frayed/damaged, liquid is spilled into the monitor, or the monitor/case is damaged.
- A certified line (H05VV-F, 3G, 0.75 mm²) is required for power connection for devices up to 6A and above 3 kg.
- Use only with power supply type: Li-shin, LSE 9802A1240.
