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. These recommendations
are consistent with the independent research and recommendations of
Wireless Technology Research.
Persons with pacemakers:

should always keep the phone more than 15 cm (6 inches) from their
pacemaker when the phone is switched on.

should not carry the phone in a breast pocket.

should use the ear opposite the pacemaker to minimize potential
interference.
If you have any reason to suspect that interference is taking place, switch
your phone off immediately.
Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the
event of such interference, you may wish to consult your hearing aid
manufacturer to discuss alternatives.
