150 kHz to 80 MHz
Field strength from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
Field strengths from fixed transmitters, such as base stations for radio cellular / cordless telephones
and land mobile radios, amateur radios, AM and FM radio broadcasts, and TV broadcasts 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
ViroVac
©
Surgical Smoke Evacuator
is used exceeds the applicable RF compliance level above, the ViroVac
©
Surgical Smoke Evacuator
should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the ViroVac
©
Surgical Smoke Evacuator
.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
NOTE:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE:
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structure, objects, and people.
