ResMed S8 ESCAPE SYSTEM, s8 English, Immunity test, IEC60601-1-2, Compliance, test level

Guidance and manufacturer’s declaration—electromagnetic immunity

The S8 series of devices is intended for use in the electromagnetic environment specified below. The customer or the user of the S8 device should assure that the device is used in such an environment.

			Portable and mobile RF communications
			equipment should be used no closer to any part
			of the S8 device, including cables, than the
			recommended separation distance calculated
			from the equation applicable to the frequency of
			the transmitter.
			Recommended separation distance
Conducted RF	3 Vrms	3 Vrms	d = 1.17 √P
IEC 61000-4-6	150 kHz to 80 MHz
Radiated RF	10 V/m	10 V/m	d = 0.35 √P 80 MHz to 800 MHz
IEC 61000-4-3	80 MHz to 2.5 GHz
			d = 0.70 √P 800 MHz to 2.5 GHz
			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:

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.

aField 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 S8 device is used exceeds the applicable RF compliance level above, the S8 device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the S8 device.

bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
