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.
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 off your phone immediately.

an explosion or fire resulting in bodily injury or even
death.
Users are advised to switch off the phone while at a
refueling point (service station). Users are
reminded of the need to observe restrictions on the
use of radio equipment in fuel depots (fuel storage
and distribution areas), chemical plants or where
blasting operations are in progress.
Areas with a potentially explosive atmosphere are
often but not always clearly marked. They include
