cable plug. If you use a power extension cable, use the appropriate type, 2-prong or 3-prong, to mate with the AC adapter power cable. l Be sure that nothing rests on your AC adapter's power cable and that the cable is not located where it can be tripped over or stepped on. l If you are using a multiple-outlet power strip, use caution when plugging the AC adapter's power cable into the power strip. Some power strips may allow you to insert the plug incorrectly. Incorrect insertion of the power plug could result in permanent damage to your media base, as well as risk of electric shock and/or fire. Ensure that the ground prong of the power plug is inserted into the mating ground contact of the power strip. Battery l Use only Dell™ battery modules that are approved for use with this media base. Use of other types may increase the risk of fire or explosion. l Do not carry a battery pack in your pocket, purse, or other container where metal objects (such as car keys or paper clips) could short-circuit the battery terminals. The resulting excessive current flow can cause extremely high temperatures and may result in damage to the battery pack or cause fire or burns. l The battery poses a burn hazard if you handle it improperly. Do not disassemble it. Handle a damaged or leaking battery pack with extreme care. If the battery is damaged, electrolyte may leak from the cells and may cause personal injury. l Keep the battery away from children. l Do not store or leave your media base or battery pack near a heat source such as a radiator, fireplace, stove, electric heater, or other heatgenerating appliance or otherwise expose it to temperatures in excess of 60ºC (140ºF). When heated to excessive temperatures, battery cells could explode or vent, posing a risk of fire. l Do not dispose of your computer's battery in a fire or with normal household waste. Battery cells may explode. Discard a used battery according to the manufacturer's instructions or contact your local waste disposal agency for disposal instructions. Dispose of a spent or damaged battery promptly. Air Travel l Certain Federal Aviation Administration regulations and/or airline-specific restrictions may apply to the operation of your Dell computer while you are on board an aircraft. For example, such regulations/restrictions may prohibit the use of any personal electronic device (PED) that has the capacity for intentional transmission of radio frequency or other electromagnetic signals while on an aircraft. ¡ In order to best comply with all such restrictions, if your Dell portable computer is equipped with Dell TrueMobile™ or some other wireless communication device, please disable this device before you board the aircraft and follow all instructions provided by airline personnel with regard to such device. ¡ Additionally, the use of any PED, such as a portable computer, may be prohibited in aircraft during certain critical phases of flight, for example, takeoff and landing. Some airlines may further define the critical flight phase as any time the aircraft is below 3050 m (10,000 ft). Please follow the airline's specific instructions as to when the use of a PED is allowed. EMC Instructions Use shielded signal cables to ensure that you maintain the appropriate electromagnetic compatibility (EMC) classification for the intended environment. For parallel printers, a cable is available from Dell. If you prefer, you can order a cable from Dell at its worldwide website at www.dell.com. Static electricity can harm electronic components inside your media base. To prevent static damage, discharge static electricity from your body before you touch any of your media base's electronic component. You can do so by touching an unpainted metal surface on the media base's input/output panel. WARNING: Handling the cord on this product, or cords associated with accessories sold with this product, will expose you to lead, a chemical known to the State of California to cause birth defects or other reproductive harm. Wash your hands after handling the cord. When Using Your Media Base Observe the following safe-handling guidelines to prevent damage to your media base: l When setting up the media base for work, place it on a level surface. l When traveling, do not check the media base as baggage. You can put your media base through an X-ray security machine, but never put your media base through a metal detector. l When traveling, do not place the media base in overhead storage compartments where it could slide around. Do not drop your media base or subject it to other mechanical shocks. l Protect your media base, battery, and hard drive from environmental hazards such as dirt, dust, food, liquids, temperature extremes, and overexposure to sunlight. l When you move your media base between environments with very different temperature and/or humidity ranges, condensation may form on or within the media base. To avoid damaging the media base, allow sufficient time for the moisture to evaporate before using the media base.
