NOTE 1:
At 80 MHz and 800 MHz, the higher frequency range
applies .
NOTE 2:
These guidelines may not apply in all situations .
Electromagnetic propagation is affected by absorption and

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 RF generator is used exceeds the applicable RF compliance
level above, the RF generator should be observed to verify normal operation . If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating
the RF generator .
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
NovaSure RF controller
The NovaSure RF controller is intended for use in the
electromagnetic environment in which radiated RF disturbances
are controlled . The customer or the user of the NovaSure RF
controller can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the NovaSure RF
controller as recommended in the following table, according to the
maximum output power of the communications device .

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 1:
At 80 MHz and 800 MHz, the separation distance for the
higher frequency range applies .
