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.

16

User Guide

2.2.1 Basic Hand Gestures

1. Single Click / Double Click

For the item selected on the touch screen, with one finger touch it very gently 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.

User Guide

17

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.

18

User Guide

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.

about 5 FP

User Guide

19

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.

20

User Guide

7. Rotation Operation

Use two figures to lightly touch the desired item on the touch screen, then rotate them in the desired direction. For example: you can rotate the picture which is being displayed in Windows Photo Viewer.

User Guide

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.

User Guide

25

5. The recognition of touch gestures by this product can be influenced by the following factors:

• Touching the correct place on the screen

• The speed of movement

• The time interval from when the screen was last touched

Note: To learn accurate hand gesture operations, the user can consult this manual and also the related Windows help content.

6. In order to achieve a better degree of sensitivity from the touch screen, the user should avoid placing the screen too close to an artificial light source or in the direct path of strong sunlight.

7. The touch screen does not function in Rescue System mode.

8. The touch screen also does not function during the startup process, and in

Sleep mode or Safe mode.

5.6 Performing Daily Maintenance Tasks

Cleaning the computer components

Because many of the computer components consist of sophisticated integrated circuit boards, it is very important to periodically clean around the computer to prevent dust buildup. The cleaning supplies you need in order to clean the components include: a vacuum cleaner, a soft cotton cloth, clear water (pure water preferred) and cotton swabs.

Attention: Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.

User Guide

37

Note: To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only use products specifically designed for cleaning displays, and follow the instructions that are included with the product.

The following are general methods for cleaning the components:

• You can use a soft cloth to remove dust on the surface of the computer, the monitor, the printer, the speakers and the mouse.

• You can use a vacuum cleaner to clean in otherwise inaccessible corners.

• To clean the keyboard thoroughly, shut down the computer and scrub it gently with a wet cloth.

• Do not use the keyboard until it is dry.

Do not do any of the following:

• Allow water to enter the computer

• Use a heavily dampened cloth

• Spray water directly onto the surface of the monitor or inside of computer

Daily attention should be given to LCD monitors. Use a dry cloth daily to brush dust from the monitor and keyboard. Keep all surfaces clean and free of grease stains.

During installation never abort the install process by powering the system off or through other drastic means. This can cause system program disorder or even failure during system initialization.

During the uninstall process, never directly delete the files or folders. This is harmful to the system, and might cause a system-wide malfunction.

Use the following procedure to properly uninstall programs:

1. Back up all documents and system settings related to the program before removing it.

2. If the program has its own uninstaller, run it directly to uninstall the program.

3. If the program does not have its own uninstaller, then select Control Panel from

Start menu.

4. From the Control Panel, choose Programs and Functions.

Problem: The capacity of the hard disk, as indicated by the system, is less than the nominal capacity.

Troubleshooting and problem resolution: For computers equipped with the

OneKey Recovery feature, the system recovery feature needs to occupy some hard disk space. This may account for the apparent hard disk capacity deficit.

Further Technical Explanation: The nominal capacity of the hard disk is expressed in the decimal system, 1000 bytes. But the actual hard disk capacity is expressed in the binary system as 1024 bytes (For example, the nominal capacity

1G is 1000M, while the actual capacity 1G is 1024M).

The capacity of the hard disk shown in Windows can be calculated according to the calculations in the following example:

The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000 x 1000/ (1024 x 1024 x 1024) = 37G.

If the Service partition of 3G - 3 x 1000 x 1000 x 1000/ (1024 x 1024 x 1024)

= 2.79G is subtracted, the capacity of the hard disk shown in the system can be obtained.

The capacity of the hard disk as calculated using this method may be slightly different from the actual capacity due to the rounding of totals.

6.5 Special considerations for troubleshooting Windows

Record the following information that may later be useful in troubleshooting system problems:

1. The serial number of the software. The serial number was shipped with the computer and was provided separately by the manufacturer. The Help Center is unable to retrieve this number.

2. The drivers for this computer model only support the Windows 7 system.

3. When you use the Windows Media Center to watch TV, be particularly attentive to the following:

• In the following two situations, you must re-save a channel list: a. When you change your TV signal from digital to analog, your saved channel list for digital TV is deleted. When you want to watch digital TV again, you must create and save a new channel list.

b. When you change your TV signal from analog to digital, your saved channel list for analog TV is deleted. When you want to watch analog TV again, you must create and save a new channel list.
