Remove the USB cable and connect it again in 10 seconds. - Make sure that your PC’s power cord is firmly plugged into a power outlet and restart your PC. - Touch may not respond when the system is down due to the unstable network. Reconnect the LAN cable or restart your PC. - If your PC and product are not connected using a signal cable, touch does not respond. Check the signal cable connection. - Touch may not respond when the product is powered off. Check the product power. - If you do not use a grounded outlet, it may cause a break or touch error. Always connect the power cord to a grounded outlet. - Check if the screen is currently on. - A break or touch error may occur as below case. If touching the screen only with nail or fingertip • The location of a touch does not correspond to the touch coordinates. - This may occur when the touch screen is not calibrated properly. Change your tablet PC settings. • A touch is applied to a monitor other than the one I intended. - This may occur if the monitor is not set as the default monitor when you are using multiple monitors. Set the monitor as the default monitor. - This may occur when the touch screen is not calibrated properly. Change your tablet PC settings. • Multi-touch does not respond. - The content played (e.g. Flash Player, Paint, etc.) may not support Multi-touch points. Make sure that you use a content that supports Multi-touch point. - Remove the USB cable and connect it again in 10 seconds. - Run the content (e.g. Flash Player, Paint, etc.) again. - Restart your PC. - On the edge of the touch screen, multi-touch may work unstably. - If the interval between two touches is too short, a touch error may occur. 27 Image sticking • After-image appears when the product is turned off. - If you use a fixed image for a long time, the pixels may be damaged. Use the screen-saver function. - When a dark image is displayed on the screen after an image with high contrast (black and white or gray), this may cause image sticking. This is normal for display products. • When the LCD panel displays a static image for an extended period of time, it can cause a voltage difference between the electrodes that operate the liquid crystals. When the voltage difference between the electrodes builds up over time, liquid crystals have a tendency to remain aligned in one direction. During this process, a previously displayed image remains visible. This phenomenon is referred to as image sticking. • Image sticking does not occur when using constantly changing images but may occur when using a fixed image for an extended period of time. Therefore, it is recommended that you use the instructions below to decrease the likelihood of image sticking occurring when using a fixed image. It is recommended that you change the screen at least once every 12 hours at the very minimum; if done more frequently, the prevention of image sticking is more effective. 28 • Recommended operating conditions 1 Change the background and the character colours using the same time interval. - When changing colours, using complementary colours helps to prevent image sticking. A A ITO or MoTi Pixel Layer 2 Change the image using the same time interval. - Make sure that the characters or images before changing the image remain in the same location after changing the image. 29 PRODUCT SPECIFICATIONS The product specifications below may be changed without prior notice due to upgrade of product functions. “ ” refers to alternating current (AC), and “ ” refers to direct current (DC).
