The level of interference will depend on the type of hearing device and the distance from the
interference source, increasing the separation between them may reduce the interference. You
may also consult your hearing aid manufacturer to discuss alternatives.
Medical devices
Please consult your doctor and the device manufacturer to determine if operation of your device
may interfere with the operation of your medical device.
Hospitals
Switch off your wireless device when requested to do so in hospitals, clinics or health care facilities.
These requests are designed to prevent possible interference with sensitive medical equipment.
Aircraft
Switch off your wireless device whenever you are instructed to do so by airport or airline staff.
Consult the airline staff about the use of wireless devices on board the aircraft, if your device offers a
‘flight mode’ this must be enabled prior to boarding an aircraft.
Interference in cars
Please note that because of possible interference to electronic equipment, some vehicle
manufacturers forbid the use of devices in their vehicles unless an external antenna is included
in the installation.
Explosive environments
Petrol stations and explosive atmospheres
In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless
devices such as your device or other radio equipment.
Areas with potentially explosive atmospheres include fuelling areas, below decks on boats, fuel
or chemical transfer or storage facilities, areas where the air contains chemicals or particles,
such as grain, dust, or metal powders.
Blasting caps and areas
Turn off your device or wireless device when in a blasting area or in areas posted turn off “two-
way radios” or “electronic devices” to avoid interfering with blasting operations.
