mobile phone very close to a pacemaker might cause the
device to malfunction. Avoid placing the phone over the
pacemaker, i.e. in your breast pocket. When using the
phone, place it at your ear opposite the pacemaker. If a min-
imum distance of 15 cm is kept between the phone and the
pacemaker, the risk of interference is limited. If you have
any reason to suspect that interference is taking place,
immediately turn off your phone. Contact your cardiologist
for more information.
Some hearing aids might be disturbed by mobile phones. In
the event of such disturbance, you may want to consult
your service provider, or call the customer service line to
discuss alternatives.
Aircraft
• Turn off your mobile phone before boarding any air-
craft.
• Do not use it on the ground without crew permission.
To prevent interference with communication systems, you
must not use your mobile phone while the plane is in the
air.
Blasting Areas
Turn off your mobile phone when in a blasting area or in
areas posted “turn off two-way radio” to avoid interfering
with blasting operations. Construction crews often use
remote control RF devices to set off explosives.
Potentially Explosive Atmospheres
Turn off your mobile phone when in any area with a poten-
tially explosive atmosphere. It is rare, but your phone or its
accessories could generate sparks. Sparks in such areas
could cause an explosion or fire resulting in bodily injury
or even death.
