Safety Information
physician before playing video games or enabling a flashing-lights 
feature (if available) on your mobile device.
Discontinue use and consult a physician if any of the following 
symptoms occur: convulsion, eye or muscle twitching, loss of 
awareness, involuntary movements, or disorientation. It is always 
a good idea to hold the screen away from your eyes, leave the 
lights on in the room, take a 15-minute break every hour, and stop 
use if you are very tired.
Caution About High Volume Usage
Listening at full volume to music or voice through a 
headset may damage your hearing.
Repetitive Motion
When you repetitively perform actions such as pressing keys or 
entering finger-written characters, you may experience occasional 
discomfort in your hands, arms, shoulders, neck, or other parts of 
your body. If you continue to have discomfort during or after such 
use, stop use and see a physician.
