General Safety Precautions
Always observe the following, general safety precautions:
• Opening any device can present electric shock, device damage, re, and/or personal injury risks and other hazards.
Exercise caution when undertaking these activities as described in this manual. Only skilled IT technicians should
undertake activities detailed within this guide.
• Do not attempt to open a device if you have received a report indicating the device has emitted “smoke” or if it
exhibits melting or other heat damage on the device casing. Contact Microsoft directly for information about
proper device disposition.
• Do not attempt to open a device that has experienced an expanded or otherwise damaged battery. Contact
Microsoft directly for information about proper device disposition.
• Always select and use the appropriate AC power supply for a device. We recommend you use genuine Microsoft
power supply units and AC power cords. A genuine Microsoft power supply unit is provided with every device.
• Use only AC power provided by a standard (mains) wall outlet. Do not use non-standard power sources, such as
generators or inverters, even if the voltage and frequency appear acceptable.
• Improper use of device batteries may result in re or explosion. Only open the enclosure on a device as outlined in
this manual. Do not heat, puncture, mutilate, or dispose of devices or their batteries in re. Do not impact, deform,
or bend device batteries. Do not leave or charge devices in direct sunlight or exposed to other extreme sources
of heat for an extended period of time. Doing so may cause damage or melt the batteries or result in exothermic
battery failure.
