Operating Environment
Remember to follow any special regulations in force in
any area and always switch your phone off whenever it
is forbidden to use it, or when it may cause interference
or danger. When connecting the phone or any accessory
to another device, read its user's guide for detailed
safety instructions. Do not connect incompatible
products.
As with other mobile radio transmitting equipment,
users are advised that for the satisfactory operation of
the equipment and for the safety of personnel, it is
recommended that the equipment should only be used
in the normal operating position (held to your ear with
the antenna pointing over your shoulder if you are
using an external antenna).
Using Your Phone Near Other Electronic Devices
Most modern electronic equipment is shielded from
radio frequency (RF) signals. However, certain
electronic equipment may not be shielded against the
RF signals from your wireless phone. Consult the
manufacturer to discuss alternatives.
Pacemakers
Pacemaker manufacturers recommend that a
minimum distance of 15 cm (6 inches) be maintained
between a wireless phone and a pacemaker to avoid
potential interference with the pacemaker.
