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 (e.g. electronic fuel injection
systems, electronic anti-skid (anti-lock) 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 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 below deck on boats; chemical
transfer or storage facilities; vehicles using liquefied petroleum gas
(such as propane or butane); areas where the air contains chemicals
or particles, such as grain, dust or metal powders; and any other area
where you would normally be advised to turn off your vehicle engine.
Vehicles
Only qualified personnel should service the phone, or install the
phone in a vehicle. Faulty installation or service may be dangerous
and may invalidate any warranty which may apply to the unit.
Check regularly that all wireless phone equipment in your vehicle is
mounted and operating properly.
