Electromagnetic Interference/Compatibility
NOTE: Nearly every electronic device is susceptible to electromagnetic 
interference (EMI) if inadequately shielded, designed, or otherwise 
configured for electromagnetic compatibility. It may be necessary to 
conduct compatibility testing to determine if any electronic equipment used 
in or around vehicles or near fixed site antenna is sensitive to external RF 
energy or if any procedures need to be followed to eliminate or mitigate the 
potential for interaction between the radio transmitter and the equipment 
or device.
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.
Vehicles
To avoid possible interaction between the radio transmitter and any vehicle 
electronic control modules, for example, ABS, engine, or transmission controls, 
the radio should be installed only by an experienced installer and that the 
following precautions be used when installing the radio: 
1. Refer to the manufacturer’s instructions or other technical bulletins or 
recommendations on radio installation. 
2. Before installing the radio, determine the location of the electronic control 
modules and their harnesses in the vehicle.
3. Route all radio wiring, including the antenna transmission line, as far away as 
possible from the electronic control units and associated wiring.
