116 Guidelines for Safe and Efficient Use
Most modern electronic equipment, for example equipment in hospitals and
cars, is shielded from RF energy. However, certain electronic equipment is
not, therefore:
• Do not use your mobile phone near medical equipment without requesting
permission.
Mobile phones may affect the operation of some implanted cardiac
pacemakers and other medically implanted equipment. Pacemaker patients
should be aware that the use of a 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 minimum 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 services line to discuss alternatives.
• Turn off your mobile phone before boarding any aircraft.
• 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.
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.
