2.7. Environmental requirements
Keep your telephone dry.
Do not expose it to extremes of
temperature (hot or cold).
Do not place your phone next to burning
cigarettes, open flames or other heat
sources.
Do not drop or bang the telephone and
do not shake it. Rough handling can
damage the internal circuitry.
Do not paint your telephone as the paint
could block the microphone, the ear
piece or hinder moving parts and thus
prevent normal use.
Treat your telephone carefully and store it
in a clean and dust-free location.
Under no circumstances attempt to
open the telephone or battery. Any
modification to the device is prohibited
and will invalidate the guarantee.
