ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
NOTE:
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if
inadequately shielded, designed or otherwise configured for electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility
where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment
that is sensitive to external RF energy.
Aircraft
When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in
accordance with applicable regulations per airline crew instructions.
Medical Devices
Pacemakers
The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation
of 15 cms (6 inches) be maintained between a handheld wireless radio and a pacemaker.These
recommendations are consistent with those of the U.S. Food and Drug Administration.
Persons with pacemakers should:
●
ALWAYS keep the radio more than 15 cms from their pacemaker when the radio is turned ON.
●
Not carry the radio in the breast pocket.
●
Use the ear opposite the pacemaker to minimize the potential for interference.
●
Turn the radio OFF immediately if you have any reason to suspect that interference is taking place.
Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such interference,
you may want to consult your hearing aid manufacturer to discuss alternatives.
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine if
it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this
information.
Use of Communication Devices While Driving
Always check the laws and regulations on the use of radios in the areas where you drive.
●
Give full attention to driving and to the road.
●
Use hands-free operation, if available.
●
Pull off the road and park before making or answering a call, if driving conditions or regulations so
require.
