Guidelines for safe and effi cient use
Damage to your hearing can occur if you are
exposed to loud sound for long periods of time.
We therefore recommend that you do not turn
on or off the handset 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.

NOTE:
Excessive sound pressure
from earphones and headphones can
cause hearing loss.
