Operating environment
Remember to follow any special regulations in force in any area and always switch off your
phone whenever it is forbidden to use it, or when it may cause interference or danger.
Use the phone only in its normal operating positions.
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 wireless phone.
PACEMAKERS
Pacemaker manufacturers recommend that a minimum separation of at least 6 inches
(approximately 20 cm) be maintained between a handheld 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 phone more than 6 inches (20 cm) 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 the potential for interference.
• Switch off the phone immediately if you have any reason to suspect that interference is
taking place.
HEARING AIDS
Some digital wireless phones may interfere with some hearing aids. In the event of such
interference, you may want to consult your service provider.
Other medical devices
Operation of any radio transmitting equipment, including cellular phones, may interfere with the
functionality of inadequately protected medical devices. Consult a physician or the manufacturer
of the medical device to determine if they are adequately shielded from external RF energy or
if you have any questions. Switch off your phone in health care facilities when any regulations
posted in these areas instruct you to do so. Hospitals or health care facilities may be using
equipment that could be sensitive to external RF energy.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor
vehicles (for example, electronic fuel injection systems, electronic antiskid/antilock braking
systems, electronic speed control systems, air bag systems). Check with the manufacturer or its
representative regarding your vehicle. You should also consult the manufacturer of any
equipment that has been added to your vehicle.
POSTED FACILITIES
Switch your phone off in any facility where posted notices so require.
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 property
and/or bodily injury or even death.
Users are advised to switch off the phone when at a refuelling 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.
