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 HoloLens:
• Use only the power supply unit and AC power cord that came with your HoloLens
• 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 HoloLens (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.
Battery Safety
The HoloLens 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 HoloLens in direct
sunlight for an extended period of time, which could cause melting or battery damage. The battery in
the HoloLens is not user replaceable.
Potentially Explosive Atmospheres
Areas with potentially explosive atmospheres are often, but not always, posted and can include
fueling areas, such as below decks on boats, fuel or chemical transfer or storage facilities, or areas
where the air contains chemicals or particles, such as grain dust, or metal powders. When you are in
such an area, turn off your HoloLens, and do not remove or install battery chargers, AC adapters, or
any other accessory. In such areas, sparks can occur and cause an explosion or fire.
Heat Related Concerns
The HoloLens may become very warm during normal use. HoloLens complies with the user-
accessible surface temperature limits defined by the International Standard for Safety of Information
Technology Equipment (IEC 60950-1).
