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.
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

If you have any reason to suspect that interference is 
taking place, switch your phone off immediately.
