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 determined 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:
Electro-surgery

coagulation mode
The OptoMonitor 3 essential performances
are not affected by electro-surgery
equipment due to the patient connection
being optic.
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 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 the OptoMonitor 3 is
used exceeds the applicable RF compliance level above, the OptoMonitor 3 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the OptoMonitor 3.
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
