Otherwise, overheating may occur that results in damage to the Tablet. As the Tablet can become very hot during operation, keep it away from objects that are vulnerable to heat. Keep the Tablet at least 13 cm (5 inches) away from electrical appliances that can generate a strong magnetic eld such as a TV, refrigerator, motor, or a large audio speaker. Avoid moving the Tablet abruptly from a cold to a warm place. A temperature dierence of more than 10 C (18 F) may cause condensation inside the unit, which may damage the storage media. 34 General Guidelines Do not place heavy objects on top of the Tablet when it is closed as this may damage the display. To avoid damaging the screen, do not touch it with any sharp object. LCD image sticking occurs when a xed pattern is displayed on the screen for a prolonged period of time. You can avoid the problem by limiting the amount of static content on the display. It is recommended that you use a screen saver or turn o the display when it is not in use. To maximize the life of the backlight in the display, allow the backlight to automatically turn o as a result of power management. Cleaning Guidelines Never clean the Tablet with its power on. Use a soft cloth moistened with water or a non-alkaline detergent to wipe the exterior of the Tablet. Gently wipe the display with a soft, lint-free cloth. If water or liquid is split onto the Tablet, wipe it dry and clean when possible. Though your Tablet is water-proof, do not leave the Tablet wet when you can dry it. If the Tablet gets wet where the temperature is 0C (32F) or below, freeze damage may occur. Make sure to dry the wet Tablet. 35 Battery Pack Guidelines The battery pack is a consumable product and the following conditions will shorten its life:

when frequently charging the battery pack. when using, charging, or storing in high temperature condition. To avoid hastening the deterioration of the battery pack thereby prolonging its useful life, minimize the number of times you charge it so as not to frequently increase its internal temperature. Charge the battery pack between 10 C ~ 30 C (50 F ~ 86 F) temperature range. A higher environment temperature will cause the battery packs temperature to rise. Avoid charging the battery pack inside a closed vehicle and in hot weather condi-

tion. Also, charging will not start if the battery pack is not within the allowed temperature range. It is recommended that you do not charge the battery pack more than once a day. It is recommended that you charge the battery pack with the Tablets power o. To maintain the battery packs operating eciency, store it in a cool dark place removed from the Tablet and with 30 % ~ 40 % charge remaining. Important guidelines when using the battery pack.When installing or removing the battery pack take note of the following:

avoid installing or removing the battery pack when the Tablet is in Sleep mode. Abruptly removing the battery pack may cause loss of data or the Tablet may become unstable. avoid touching the battery pack terminals or damage may occur, thereby causing improper operation to it or the Tablet. 36 The Tablets input voltage and surrounding temperature will directly aect the battery packs charge and discharge time:

charging time will be prolonged when the Tablet is turned on. To shorten the charging time, it is recommended that you place the Tablet in sleep or hibernation mode. a low temperature will prolong the charging time as well as hasten the discharge time. When using battery power in an extremely low temperature environment, you may experience shortened operating time and incorrect battery level reading. This phenomenon comes from the chemical characteristics of batteries. Do not leave the battery pack in storage for more than six months without recharging it. Touchscreen Guidelines se the nger or stylus on the display. Using a sharp or metallic object other than your nger or stylus may cause scratches and damage the display, thereby causing errors. Use a soft cloth to remove dirt on the display. The touchscreen surface has a special protective coating that prevents dirt from sticking to it. Not using a soft cloth may cause damage to the special protective coating on the touchscreen surface. Turn o the Tablet power when cleaning the display. Cleaning the display with the power on may cause improper operation. Do not use excessive force on the display. Avoid placing objects on top of the display as this may cause the glass to break thereby damaging the display. In low and high temperaturesthe touchscreen may have a slower response time or register the touch in the wrong location. It will go back to normal after returning to room temperature. 37 When Traveling Make sure that the battery pack is fully charged. Make sure that the Tablet is turned o. Make sure that all the connector covers are closed completely to ensure the waterproof integrity. Disconnect the AC adapter from the Tablet and take it with you. Use the AC adapter as the power source and as a battery-charger. Hand-carry the Tablet. Do not check it in as luggage. If you need to leave the Tablet in the car, put it in the trunk of the car to avoid exposing the Tablet to excessive heat. When going through airport security, it is recommended that you send the Tablet and ash disks through the X-ray machine (the device you set your bags on). Avoid the magnetic detector (the device you walk through) or the magnetic wand (the handheld device used by security personnel). If you plan to travel abroad with your Tablet, consult your dealer for the appropri-

ate AC power cord for use in your country of destination. 38 Chapter 7 Troubleshooting Tablet problems can be caused by hardware, software, or both.
