To clean, wipe the outer surface with a soft, lint-free cloth. This symbol identifies safety and health messages in this Device Guide WARNING: Read Safety & Health Info Read this guide for important safety and health information and the terms of the Limited Warranty that apply to the Microsoft ® device that you have purchased. Keep all printed guides for future reference. Failure to follow instructions and properly set up, use, and care for this product can increase the risk of serious injury or death, or damage to the device or devices. For an online version of this guide go to: www.surface.com/support Warning: Do Not Attempt Repairs Do not attempt to take apart, open, service, or modify the product, accessories, or power supply. Doing so could present the risk of electric shock or other hazard. Any evidence of any attempt to open and/or modify this device, including any peeling, puncturing, or removal of any of the labels, will void the Limited Warranty. Warning: AC Adapter Safety Failure to take the following precautions can result in serious injury or death from electric shock or fire or in damage to the device. To select an appropriate power source for your device: • Use only the power supply unit and AC power cord that came with your device or that you received from an authorized Microsoft retailer. • Do not use non-standard power sources, such as generators or inverters, even if the voltage and frequency appear acceptable. Only use AC power provided by a standard wall outlet. • Do not overload your wall outlet, extension cord, power strip, or other electrical receptacle. Confirm that they are rated to handle the total current (in amps [A]) drawn by the device (indicated on the power supply unit) and any other devices that are on the same circuit. • On devices where the AC prongs may be folded for storage, before plugging the AC adapter into a power outlet, make sure its prongs are fully extended. • On devices where the AC prongs are removable and where the power supply uses a universal adapter, before plugging the AC adapter into a power outlet, make sure the prong assembly is of the proper configuration for the power outlet and fully seated into the adapter. Caution: Cable and cord safety Arrange all cables and cords so that people and pets are not likely to trip over or accidentally pull on them as they move around or walk through the area. Do not allow children to play with cables and cords. To avoid damaging the power cords and power supply: • Protect the power cords from being walked on. • Protect cords from being pinched or sharply bent, particularly where they connect to the power outlet, the power supply unit, and the device. • Do not jerk, knot, sharply bend, or otherwise abuse the power cords. • Do not expose the power cords to sources of heat. • Keep children and pets away from the power cords. Do not allow them to bite or chew on them. • When disconnecting the power cords, pull on the plug—do not pull on the cord. • If a power cord or power supply becomes damaged in any way, stop using it immediately. • Unplug your device during lightning storms or when unused for long periods of time. • For devices with an AC power cord that connects to the power supply, always connect the power cord according to the following instructions: 1 Plug the AC power cord into the power supply until it seats fully. 2 Plug the other end of the AC power cord into the wall outlet. 3 Warning: Battery Safety Information This device contains a built-in battery, improper use of which may result in explosion. Do not heat, open, puncture, mutilate, or dispose of the product in fire. Do not leave the device in direct sunlight for an extended period of time, which could cause melting or battery damage. The battery in this device is not user replaceable and should only be replaced by Microsoft or a Microsoft Authorized Service Provider. See www.surface.com/support for additional details. • Do not disassemble or open, crush, bend or deform, puncture or shred • Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water or other liquids, expose to fire, explosion or other hazard. • Only use the battery with a charging system that has been qualified with the system per CTIA Certification Requirements for Battery System Compliance to IEEE 1725. Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or other hazard. • Promptly dispose of used batteries in accordance with local regulations • Avoid dropping the device or battery. If the device or battery is dropped, especially on a hard surface, and the user suspects damage, take it to a service center for inspection. • Improper battery use may result in a fire, explosion or other hazard. • This device shall only be connected to CTIA certified adapters, products that bear the USB-IF logo or products that have completed the USB-IF compliance program. Warning: Use Near Water To reduce the risk of fire or shock, do not use this device near water and do not expose it to rain or moisture. Do not attempt to dry device with a hair dryer or a microwave oven. Warning: Hearing Safety Set the volume loud enough to hear clearly in quiet surroundings, and no louder. Do not increase the volume after you start listening. Your ears can adapt over time so that high volume sounds normal, but the high volume may still damage your hearing. • Do not increase the volume to block out outside noise. The combination of outside noise and sound from your headphones can damage your hearing. Sealed or noise-canceling headphones can reduce outside noise so that you don’t have to turn up the volume. If you can’t understand someone nearby speaking normally, turn down the volume. Sound that drowns out normal speech can damage your hearing. Even with sealed or noise-cancel…
