manual or instruction manual shall contain this information about 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.
