topics:
Touch Screen Calibration
User Gesture Instructions for the Touch screen
Attentions when using the Touch Screen
Attention: Only some selected models are
equipped฀with฀touch฀screens.User Guide 11

12 User Guide
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.
Note: Do not touch it via hard objects like finger nails.
2.2.1 Basic Hand Gestures
1. Single Click / Double Click
For the item selected on the touch screen, with one finger touch it one or two
times, to perform a single click or double click operation. This is similar to the
action performed by clicking the left mouse button.

14 User Guide
2. Single Finger Right Click
For the item selected on the touch screen, press and hold your finger on the
screen until a circle appears. After lifting your finger from the touch screen, a menu
bar will pop up, completing the single finger right click operation. This is similar to
the action performed by clicking the right mouse button.
