Guidance and Manufacturer’s Declaration - Electromagnetic Immunity

This device is intended for use in the electromagnetic environment specified below. The user of this device should make sure it is used in such an environment.

Immunity Test	IEC 60601 Test	Compliance		Electromagnetic Environment -
	Level	Level			Guidance
			Portable and mobile RF communications equipment
			should be used no closer to any part of the 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 V	d =	1.2	P
IEC 61000-4-6	150 kHz to 80 MHz
	outside ISM bandsa
	10Vrms	10 V	d =	1.2	P
	150 kHz to 80 MHz
	in ISM bandsa
Radiated RF	10 V/m	10 V/m	d =	1.2	P 80 MHz to 800 MHz
IEC 61000-4-3	80 MHz to 2.5 GHz	26 MHz to 2.5 GHz	d =	2.3	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 surveya, 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 device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.

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