Seizures/Blackouts

The phone can produce a bright or flashing light. A small
percentage of people may be susceptible to blackouts or
seizures (even if they have never had one before) when exposed
to flashing lights or light patterns such as when playing games or
watching video. If you have experienced seizures or blackouts or
have a family history of such occurrences, please consult a
physician. To reduce the risk of blackouts or seizures, you can
use your phone in a well-lit room and take frequent breaks.

Repetitive Stress Injuries

To minimize the risk of Repetitive Strain Injury (RSI) when texting
or playing games with your phone:
 Do not grip the phone too tightly.

Press the buttons lightly.
 Use the special features that are designed to minimize the
times of pressing buttons, such as Message Templates and
Predictive Text.
 Take many breaks to stretch and relax.

Emergency Calls

This phone, like any wireless phone, operates using radio signals,
which cannot guarantee connection in all conditions. Therefore,
you must never rely solely on any wireless phone for emergency
communications.
