where P is the maximum
output power rating of the
transmitter in watts (W)
according to the
transmitter manufacturer
and d is the recommended
separation distance in
meters (m).
Field strengths from
fixed RF transmitters, as
deter-mined by an
electromagnetic site
survey, a) should be
less than the compliance
level in each frequency
range.
b) Interference may occur in
the vicinity of equipment
marked with the following
symbol:
NOTE 1 A t 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 broadcast and TV
broadcast 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 Optune Treatment Kit is
used exceeds the applicable RF compliance level above, Optune Treatment Kit should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating Optune Treatment Kit
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
