Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the Receiver
The receiver is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the receiver can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the receiver as recommended below, according to the maximum output power of the communications
equipment. Portable and mobile RF equipment include: baby monitors, Bluetooth wireless headsets,
wireless routers, microwave ovens, laptops with internal wi-fi adapters, GSM cell phones, RFID scanners
and hand-held security metal detector often used by security screeners.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
(d) in feet can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacture.
NOTE 1:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE
2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
