  • Brightness buttons. When you're wearing the HoloLens, the brightness buttons are on the left side of the device.
  • Volume buttons. When you're wearing the HoloLens, the volume buttons are on the right side of the device.
  • Device arms. When you pick up, put on, or take off your HoloLens, always grasp or hold it by the device arms.

In the box

The HoloLens box contains the following items:

  • Nose pads. Select a nose pad that fits the shape of your nose and accommodates your eyewear.
  • Overhead strap. When you're wearing the HoloLens while you move around, use the overhead strap to help keep the device in place. Additionally, if you're wearing the HoloLens for extended periods, using the overhead strap makes the device more comfortable to wear.
  • Micro USB cable. Use the micro-USB cable to connect your HoloLens to the power supply for charging, or use it to connect your HoloLens to your computer.
  • Power supply. Plugs into a power outlet.
  • Microfiber cloth. Use the cloth to clean your HoloLens visor.

Safety

HoloLens is tested and is found to conform to the basic impact protection requirements of ANSI Z87.1, CSA Z94.3, and EN 166.

Care and cleaning

Handle your HoloLens carefully. To lift, carry, and adjust your HoloLens, use the device arms—not the overhead strap. To keep the visor free of dust and fingerprints and avoid touching it. Repeated cleaning could damage the visor, so try to keep your device clean.

Don't use any cleaners or solvents on your HoloLens, and don't submerge it in water or apply water directly to it.

To clean the visor, remove any dust using a camel or goat hair lens brush or a bulb-style lens blower. Lightly moisten the microfiber cloth with a small amount of distilled water, then use it to wipe the visor gently in a circular motion.

To clean the rest of the device, including the headband and device arms, use a lint-free cloth moistened with mild soap and water. Let your HoloLens dry completely before using it again.
