• Reduce 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 use and see a
physician.
• If your device has a camera flash or light, do not use
the flash or light close to the eyes of people or pets.
