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, use your phone in a well-lit room and take
frequent breaks.
Repetitive Strain 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 which are designed to minimize the
times of pressing buttons, such as Message Templates and
Predictive Text.

Take frequent breaks to stretch and relax.
Emergency Calls
This phone, like any other 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.
