Interference control: Electromagnetic Interference (EMI) is any signal or emission, radiated in free
space or conducted along power or signal leads, that endangers the function of radio navigation or other
safety service (the telephone and cellphones are considered to be safety services) or seriously
degrades, obstructs or repeatedly interrupts a licensed radio communications service. Radio
communications services include but are not limited to: AM/FM commercial broadcast, television,
cellular services, radar, air traffic control, pager and personal communications services (PCS). These
licensed services, along with unintentional radiators such as digital devices, including computer
systems, contribute to the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly
together in the electromagnetic environment. While this device has been designed and determined to
be compliant with regulatory agency limits for EMI, there is no guarantee that interference will not occur
in a particular installation. If this device does cause interference with radio communications services,
which can be determined by turning the device on and off, you are encouraged to try to correct the
interference by one or more of the following measures:
• Re orient the receiving antenna.
• Relocate the device with respect to the victim receiver.
• Move the device away from the victim receiver.
• Plug the device host into a different power outlet than the victim receiver so that the device
system and receiver are on separate branch circuits.
If necessary, consult your system service representative or an experienced radio/television technician
for additional help in resolving interference.
