Use caution when exposed to flashing lights
While using your device, leave some lights on in the room and 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.
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 use and see
a physician.

Avoid charging batteries for more than a week, as overcharging may shorten
battery life.
