Guidance and manufacturer’s declaration-electromagnetic immunity

The ET1928L is intended for use in the electromagnetic environment specified below. The user of the ET1928L should assure that it is used in such an environment.

Immunity test	IEC 60601 test level	Compliance	Electromagnetic environment-guidelines
		level
			Portable and mobile RF communications equipment
			should be used no closer to any part of theET1928L,
			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=1.2 P
Radiated RF	3 V/m	3 Vrms	d=1.2 P 80MHz to 800 MHz
IEC 61000-4-3	80 MHz to 2.5 GHz
			d=2.3 P 800 NHz to 2.5GHz
			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 metres(m)
			Filed strengths from fixed RF transmitters, as
			determined by an electromagnetic site survey 3,
			should be less than the compliance level in each
			frequency range4.
			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 situation. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

3.Filed 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 filed strength in the location in which the ET1928L is used exceeds the applicable RF compliance level above, the ET1928L should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the ET1928L.

4.Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 Vrms.
