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 6 inches (15 centimeters) 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 6 inches (15 
centimeters) from their pacemaker when the radio 
is turned ON.
• Not carry the radio in the breast pocket.
