4.2 Installation

This analog LCD display DOES NOT require any special drivers. Necessary drivers are supplied by the video card manufacturer and may be found on the diskettes supplied with the video card that came with your computer. Windows 95/98 drivers for both the display and the video card are supplied on the Windows 95/98 CD or diskettes. Unfortunately, Microsoft did not provide a complete listing of the displays on the initial retail release. You may use the standard SVGA (800 x 600 @ 60) as the display type. The video card must also be set up correctly in Windows 95/98 and make sure the video output of the VGA card is on list in Section 5.1 or check your Video Card manual or Windows 95/98 Read me file for further information on Video Card. After the question listed above is solved, we continue the setup procedure as below.

1. Turn power off both Computer and Display before making any connection.

2. Install Display on the solid horizontal surface such as a table or desk.

3. Connect the power cable to the back of the LCD monitor.

4. Connect the signal cable on the rear of the monitor to the 15-pin connector on the rear of the computer and tighten the screws.

IBM PC’s & Compatibles

Connect one end of the signal cable to the 15-pin connector on the rear of the computer.

Apple/Macintosh

TOUCH SCREEN

Introduction

Touch screens are a common means to interface operator inputs to a system. The universal standard of Windows GUI (Graphical User Interface) has significantly increased the use of touch screens.

There are four main touch technologies. The technologies are resistive, surface acoustic wave (SAW), capacitive, and infrared (IR). Each touch technology has advantages and disadvantages based on different user applications.

Installation

All Vartech Systems displays configured with a touch screen are supplied with a CDROM which includes user manuals, application software, and drivers for various operating systems. Insert the supplied CDROM into a CDROM drive and follow the installation instructions that will appear on the screen.

Limited technical support is available by contacting Vartech Systems customer support at 800-223-8050.

CLEANING AND MAINTENANCE

Cleaning

Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked) with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the screen surface to avoid scratching it with accumulated grit.

Note:

The solvent should be applied only to the cloth, and not directly on the monitor screen. Do not use paper products as they may scratch the surface. To minimize the risk of abrasion, allow the screen to stand dry. Special care should be taken when cleaning a touch screen or polycarbonate shield that is installed over the screen. Abrasive and certain chemical cleaners can easily damage the surface.

Never use alcoholic or ammoniac cleaners to clean the polycarbonate shield or a touch screen.

Replacing a Line Cord

To avoid shock and fire hazards, the monitor’s power cord should be replaced if the insulation becomes broken or if it develops a loose internal connection.

Other Maintenance

Qualified service personnel should perform all maintenance, except for the power cord replacement described above.
