Caution About High Volume Usage; Repetitive Motion - Motorola MOTO EM330 User Manual

If you have experienced seizures or blackouts or if you have a family
history of such occurrences, please consult with your doctor before
playing video games or enabling a flashing-lights feature (if available)
on your mobile device.
Discontinue use and consult a doctor 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
doctor.
