Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 6 in. (15.3 cm) be
maintained between a 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 device more than 6 in. (15.3 cm) from their pacemaker when the device
is switched on;
• not carry the device in a breast pocket; and
• hold the device to the ear opposite the pacemaker to minimise the potential for
interference.
If you have any reason to suspect that interference is taking place, switch off your device
immediately.
Hearing aids
Some digital wireless devices may interfere with some hearing aids. If interference occurs,

■ Potentially explosive environments
Switch off your device when in any area with a potentially explosive atmosphere and obey
all signs and instructions. Potentially explosive atmospheres include areas where you would
normally be advised to turn off your vehicle engine. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even death. Switch off the device at refuelling
points such as near gas pumps at service stations. Observe restrictions on the use of radio
