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

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.
Other medical devices
If you use any other personal medical devices, consult
the manufacturer of your device to determine if it is
adequately shielded from external RF energy.
