Radio Frequency Interference

General Statement on Interference
Care must be taken when using the device in close proximity to personal medical devices, such as pacemakers and hearing aids.
Please consult your doctor and the device manufacturers to determine if the operation of your watch may interfere with the operation of your medical devices.

Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 15 cm be maintained between a mobile device and a pacemaker to avoid potential interference with the pacemaker. To achieve this, use the device on the opposite ear to your pacemaker and do not carry it in a breast pocket.

Hearing Aids
People with hearing aids or other cochlear implants may experience interfering noises when using wireless devices or when one is nearby.
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 Equipment
Turn off your wireless device when you are requested to do so in hospitals, clinics or health care facilities. These requests are designed to prevent possible interference with sensitive medical equipment.

Aircraft
Turn 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 onboard the aircraft. If your device offers a ‘airplane mode’, this must be enabled prior to boarding an aircraft.

Interference in Vehicles
Please note that because of possible interference with electronic equipment, some vehicle manufacturers forbid the use of mobile devices in their vehicles unless a hands-free kit with an external antenna is included in the installation.

Explosive Environments

Gas Stations and Explosive Atmospheres
In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless devices such as your watch or other radio equipment.
Areas with potentially explosive atmospheres include fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders.

Blasting Caps and Areas
Power off your mobile device when in a blasting area or in areas where signs are posted to power off “two-way radios” or “electronic devices” to avoid interfering with blasting operations.
