Electronic Devices
Most modern electronic equipment is shielded from radio frequency (RF) signals. However,
certain electronic equipment may not be shielded against the RF signals from your mobile
phone.
Pacemakers
Using the phone within 6 inches (20cm) may cause a potential interference with a
pacemaker.
Persons with pacemakers:
Should always keep the phone more than 6 inches (15cm) from their pacemaker when the
phone is switched on.
Should not use the phone near around their chests.
Should use the ear opposite the pacemaker to minimize the potential for interference.
If you have any reason to suspect that interference is taking place, switch off your phone
immediately.
Hearing Aids
Some digital mobile phones may interfere with some hearing aids. For more information,
contact your service provider.
OTHER FUNCTIONS
Other Medical Devices
Electromagnetic waves generated from the cellular phones may dangerously affect medical
devices. Switch off your phone in health care facilities in accordance with their regulations.
Car
Electromagnetic wave signals may affect improperly installed or inadequately shielded
electronic systems in a car. Check with the manufacturer regarding your car before using
your phone.
Potentially Explosive Atmospheres
Switch off your phone when in any area with a potentially explosive atmosphere and obey
all signs and instructions. Sparks in such areas could cause 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). Also
switch your phone off when you are below deck on boats; in chemical transfer or storage
facilities and in vehicles using liquefied petroleum gas as the air may contain chemicals or
particles such as grain, dust or metal powders.
