NOTE 1: At 80 MHz and 800 MHz, 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 .
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 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 CooperSurgical LEEP PRECISION
Smoke Evacuators used exceeds the applicable
RF compliance level above, the CooperSurgical
LEEP PRECISION 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 CooperSurgical LEEP PRECISION Smoke
Evacuator .
b
Over the frequency range 150 kHz to 80 MHz,
field strengths should be less than 3 V/m .
