Recommended separation distances between
portable and mobile RF communications equipment and the Estech
COBRA™ Electrosurgical HF Generator
1. The Estech COBRA™ Electrosurgical HF Generator is intended for use in an
electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Estech COBRA™ Electrosurgical
HF Generator can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Estech COBRA™ Electrosurgical HF
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 determined 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.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and
people.
