do not hold the screen too close to your eyes.
• Seizures or blackouts can occur when you are exposed to
flashing lights while watching videos or playing Flash-based
games for extended periods. If you feel any discomfort, stop
using the device immediately.
• If anyone related to you has experienced seizures or blackouts
while using a similar device, consult a physician before using
the device.

Reduce the risk of repetitive motion injuries
When you repetitively perform actions, such as pressing keys,
drawing characters on a touch screen with your fingers, or playing
games, you may experience occasional discomfort in your hands,
neck, shoulders, or other parts of your body. When using your
device for extended periods, hold the device with a relaxed grip,
press the keys lightly, and take frequent breaks. If you continue to
have discomfort during or after such use, stop using the device
and consult a physician.
