mammotome REVOLVE - RFID Frequency Information

10-6
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
Mammotome revolve Biopsy System is used exceeds the applicable RF compliance level above, the
Mammotome revolve Biopsy System should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as re-orienting or relocating the Mammotome
revolve Biopsy System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment
and the Mammotome revolve Dual Vacuum-Assisted Biopsy System
The Mammotome revolve Dual Vacuum-Assisted Biopsy System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or user can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the system as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in meters (m) 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 manufacturer.
NOTE: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
