 WARNING: Photosensitive seizures
Applies to: Surface, Xbox, HoloLens

Some people may experience a seizure when exposed to flashing lights or patterns in moving images or video games. Even people who have no history of seizures or epilepsy may have an undiagnosed condition that can cause “photosensitive seizures” while watching moving images or video games.

These seizures may have a variety of symptoms, including lightheadedness, altered vision, eye or face twitching, jerking or shaking of arms or legs, disorientation, confusion, or momentary loss of awareness. Photosensitive seizures may also cause loss of consciousness or convulsions that can lead to injury from falling or striking nearby objects. Immediately stop playing and consult a doctor if you experience any of these symptoms. Parents should watch for or ask their children about the above symptoms — children and teenagers are more likely than adults to experience these seizures. The risk of photosensitive seizures may be reduced by taking the following precautions:

  • Sit farther from the video screen.
  • Use a smaller video screen.
  • Play in a well-lit room.
  • Do not play when you are drowsy or fatigued.

If you or any of your relatives have a history of seizures or epilepsy, consult a doctor before playing.

 WARNING: Keep out of the reach of small children
Applies to: Surface, Surface Headphones, Xbox, Phone, Band, HoloLens

 CAUTION: Hearing safety
Applies to: Surface, Surface Headphones, Xbox, Phone, HoloLens

Frequent or extended exposure to loud noise or sounds when using a headset or headphones can cause temporary or permanent hearing loss. Individual susceptibility to noise-induced hearing loss and potential hearing problems varies. Also, the sound volume produced by a device may vary depending on the nature of the sound, device settings, and the headset or headphones used. As a result, there is no single volume setting that is appropriate for everyone or for every combination of sound, settings, and equipment.

Here are a few common-sense recommendations to minimize your exposure to loud noises or sounds when using a headset or headphones with your device:

  • Minimize your time listening to loud sound. All of the sound you are exposed to each day adds up. At maximum volume, listening to music or other content on your device with a headset or headphones can permanently damage your hearing in 15 minutes. If you are exposed to other loud sounds also, it takes less time listening at high volumes to cause hearing damage.
  • The more time you spend exposed to loud sounds, the more likely you are to damage your hearing. The louder the sound, the less time that is required to damage your hearing.
  • Always turn the volume on your device down before plugging a headset or headphones into your device. 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 could still damage your hearing.
  • Do not increase the volume to block outside noise. The combination of outside noise and sound from your headset or 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-canceling headphones, you should be able to hear nearby people speak.
  • To minimize the potential for hearing damage, keep the volume low enough that you can carry on a conversation with people nearby.
  • Headphones and headsets can attract dangerous objects like staples and paper clips. Always check your headset or headphones before use.
  • Use of a headset or headphones while driving may be prohibited or restricted in your area; check your local laws and regulations for further information.

Finally, be aware of hearing loss symptoms. It’s a good idea to have your hearing checked regularly by an audiologist. Stop using a headset or headphones with your device and have your hearing checked if:

  • You experience any hearing loss symptoms
  • You hear ringing in your ears
  • Your speech sounds muffled, dull, or flat
