Recommended Separation Distance
Recommended Separation Distance between portable and mobile RF
communications equipment and the CooperSurgical LEEP PRECISION
Smoke Evacuation System
The CooperSurgical LEEP PRECISION Smoke Evacuation Systems are intended
for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the CooperSurgical LEEP PRECISION
Smoke Evacuation Systems can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the CooperSurgical LEEP PRECISION Smoke
Evacuation Systems 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 rating of the transmitter
in watts (W) according to the transmitter manufacturer.
For the CooperSurgical LEEP PRECISION Smoke Evacuation System:
V1
= 3 Vrms
E1
= 3 V/m
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.
