Guidelines for safe and efficient use
Pull off the road and park before making or
answering a call if driving conditions require
you to do so.
RF energy may affect some electronic systems
in your vehicle such as car stereos and safety
equipment.
If your vehicle is equipped with an air bag,
do not obstruct with installed or portable
wireless equipment. It can cause the air bag
to fail or cause serious injury due to improper
performance.
If you are listening to music while out and
about, please ensure that the volume is at a
reasonable level so that you are aware of your
surroundings. This is of particular importance
when near roads.

Avoid damage to your hearing
To prevent possible hearing damage,
do not listen at high volume levels for
long periods.
Damage to your hearing can occur if you are
exposed to loud sounds for long periods of time.
We therefore recommend that you do not turn
the handset on or off close to your ear. We also
recommend that music and call volumes are set
to a reasonable level.
When using headphones, turn the volume down
if you cannot hear the people speaking near
you or if the person sitting next to you can hear
what you are listening to.
