The monitor has touch capability due to a touch-sensitive screen installed. A touch screen is an input device just like a mouse or a keyboard, and the user’s hand transmits position information via the touch screen to the computer. With this technology, you only need to touch the pictures or words on the computer display lightly with your finger, and the computer will react.

2.1 Touch Screen Calibration

Prior to first use or whenever the touch screen reacts in a different place where you are touching it, start the calibration program. The procedure is as follows:

1. In Windows 7, Select “Start” – “Control Panel”.

2. In Control Panel, select “Hardware and Sound”.

3. In “Hardware and Sound” window, select “Tablet PC Settings”.

4. In “Tablet PC Settings” dialogue, click “Calibrate” button.

5. Use your finger or the touch pen of 6-7mm diameter to touch each of the calibration points that are shown in sequence, to finish the calibration.

2.2 User Gesture Instructions for the Touch screen

The Touch screen supports single touches and rotational movements, enlargement and reduction multi-touch operations, and the user can transmit position information to the computer via touch. The touch screen uses a very low pressure movement recognition method, which only needs the finger to move lightly on the computer display screen or make a simple hand gesture to be detected by the main computer processor.

3. Dragging Movement

First touch your finger on the desired item on the screen and hold it there, then make a dragging movement. This is similar to the click and drag movement you can make with a mouse.

4. High Speed Slide

If you touch the screen with a single finger and slide it a short distance horizontally

(about 5 cm), then quickly lift it up again, this is called a High Speed Slide, and the screen will show the “Forward” or “Back” icon.

In the default situation, a high speed horizontal sliding movement will execute a forward or back operation. For example: Forward and Back operations for the

IE browser; or Previous and Next slide operations in Windows Photo Viewer slideshow mode.

5. Rolling Movement

When you move your finger one time vertically (or horizontally) on the touch screen, this is called a Rolling Operation. This operation is similar to moving the scroll wheel on the top of a mouse, and produces the same results as the scroll wheel interface does.

6. Zoom Operation

Touch two fingers lightly on the desired item on the touch screen, then keeping both fingers on the screen, change the distance between them. By increasing (or decreasing) the distance, you can perform a zoom out (or zoom in) operation. For example: you can enlarge or reduce the picture size in Windows Photo Viewer.

2.3 Attentions when using the Touch Screen

1. With the new touch recognition technology of Touch Screen, the user only needs to gently tap on the touch screen, and does not need to exert any pressure to complete operations. When using it please remember not to use excessive force or tear the screen surface with any sharp object.

2. In order to safeguard it for normal use, you should remove any dirt from the touch screen, and ensure your fingers are clean and dry, as well as avoid using it in dusty environments, or in very hot or humid conditions.

3. The product casing is easy to clean. To ensure safe use, we suggest you clean the screen and casing with a soft cotton cloth after turning it off each time.

When wiping the screen, please do not wipe in an upwards direction, but wipe it in a direction from top to bottom.

4. Please promptly remove any dust accumulated in the four corners of the screen and the bottom of the screen frame, because this will prevent accumulated dust from affecting the screen’s touch localization. Do not place or drop anything which could obstruct it in the four corners of the screen or any part of its frame, because this could separate the screen from the frame and stop the screen from being able to sense position properly.

Note: When it is used in normal operation, the touch screen process will not affect the running of other computer processes.
