The field strength from fixed high
frequency transmitters, as determined
by survey, should be less than the
compliance level.
Interference may occur in the vicinity of equipment marked with the symbol “non-ionizing radiation“.
NOTE
This guideline may not apply in all situations.

The field strength from fixed transmitters, such as base stations from radio
(cellular / cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast and TV broadcast, cannot be theoretical predicted with
exact accuracy.
To assess the electromagnetic environment due to fixed high frequency
transmitters, a site survey should be considered. If the measured field strength
at the location, where the electrosurgical generator is used, exceeds the above
applicable compliance level, the electrosurgical generator should be observed
to verify normal operation.
If unusual performance characteristics are observed, additional procedures may
be necessary, such as reorientation or relocating of the electrosurgical
generator.
Over the frequency range 150 kHz to 80 MHz, the field strength should be less
than 3 V/m.
The electrosurgical generator is intended for use in an electromagnetic
environment where the radiated high frequency disturbances are controlled.
The user of the electrosurgical generator can help to prevent electromagnetic
interference by maintaining a minimal distance between portable and mobile
high frequency communication equipment (transmitters) and the electrosurgical
generator, according to the maximum output power of the communication
equipment, as recommended below.
