Portable and mobile RF communications equipment should be used no closer to any part of the CS-3000 RF Generator
including cables, than the recommended separation
distance calculated from the equation:
d=6/E×√P
Where:
•
d is the separation in meters
•
P is the maximum output power rating of the transmitter
in watts (W) according to the Service
•
E is the Compliance Test Level indicated above.
Interference may occur in the vicinity of equipment marked with the following symbol:
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 elec
-
tromagnetic site survey should be considered. If the measured field strength in the location in which the ASU System or any of its components are used exceeds
the applicable RF compliance level above, the ASU System should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating components or the entire ASU 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 CS-3000 RF Generator
The CS-3000 RF Generator is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
CS-3000 RF Generator can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the CS-3000 RF Generator 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 applica-
ble 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
.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
Glossary of Terms
Electrocoagulation
Surgical procedures in which high-frequency electric current is used to coagulate tissues.
Coagulation Electrode
The metal conductor in the coagulation device used to transmit RF energy to tissue.
Indifferent, Dispersive
Electrode
Commonly referred to as the “return electrode” or “patient electrode” or “ground pad.” Large surface area ground used to complete the circuit
of the electrical current. Usually placed on the patient’s back or thigh, the Indifferent, Dispersive Electrode is connected to the generator at
the Indifferent Connector.
