Electronic Devices
Most modern electronic equipment is shielded from radio frequency (RF)
signals. However, certain electronic equipment might not be shielded
against the RF signals from your wireless phone. The following four
subsections provide more information about this topic.
Pacemakers
Pacemaker manufacturers recommend that a minimum separation of six
inches (20 cm.) should be maintained between a handheld wireless phone
and a pacemaker to avoid potential interference with the pacemaker.
These recommendations are consistent with the independent research by
and recommendations of Wireless Technology Research. Persons with
pacemakers:
• should always keep the phone more than six inches (20 cm) 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 the potential
for interference
Note: If you have any reason to suspect that interference is taking
place, switch off your phone immediately.
Hearing Aids
Some digital wireless phones could interfere with some hearing aids. In
the event of such interference, you might want to consult your service
provider.
Other Medical Devices
Operation of any radio transmitting equipment, including cellular phones,
could interfere with the functionality of inadequately protected medical
devices. Consult a physician or the manufacturer of the medical device to
determine if they are adequately shielded from external RF energy. Also
contact these authorities if you have any questions.
