Guidance and manufacture’s declaration - electromagnetic immunity

The Oxygen Saturation Monitor Model PULSOX-300 is intended for use in the electromagnetic environment specified below. The customer or the user of the Model PULSOX-300 should assure that it is used in such anenvironment.

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 inmeters (m).

Field strength 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:

NOTE 1 At 80MHz and 800MHz, 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.

aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephone 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 PULSOX-300 is used exceeds the applicable RF compliance level above, the PULSOX-300 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the PULSOX-300.

bOver the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
