Health and safety warnings
Repetitive Stress Injury
Using the Gear VR can make your muscles, joints or skin hurt. If any
part of your body becomes tired or sore while using the Gear VR,
or if you feel symptoms such as tingling, numbness, burning or
stiffness, stop and rest for several hours before using the Gear VR
again. If you continue to have any of the above symptoms or other
discomfort during or after play, stop using the Gear VR and see a
doctor.
Interference with Medical Devices
The Gear VR contains magnets and can emit radio waves.
These can affect the operation of nearby electronics, including
cardiac pacemakers, hearing aids and defibrillators. If you have a
pacemaker or other implanted medical device, do not use the Gear
VR without first consulting your doctor or the manufacturer of your
medical device. Maintain a safe distance between the Gear VR and
your medical devices, and stop using the Gear VR if you observe a
persistent interference with your medical device.
