Philips C221S3 user manual Immunity test

1. Important

Guidance and manufacturer’s declaration – electromagnetic immunity – for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING:

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

Immunity test	IEC 60601 test level	Compliance level	Electromagnetic environment – guidance
			Portable and mobile RF communications equipment
			should be used no closer to any part of the monitor,
			including cables, than the recommended separation
			distance calculated from the equation applicable to the
			frequency of the transmitter.
			Recommended separation distance:
			d = 1.2
Conducted RF	3 Vrms		d = 1.2	80 MHz to 800 MHz
		3 Vrms	d = 1.2	800 MHz to 2.5 GHz
IEC 61000-4-6	150 kHz to 80 MHz
			where P is the maximum output power rating of the
			transmitter in watts (W) according to the transmitter
Radiated RF	3 V/m	3 V/m	manufacturer and d is the recommended separation
IEC 61000-4-3	80 MHz to 2.5 GHz		distance in metres (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

•At 80 MHz and 800 MHz, the higher frequency range applies.

•These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

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

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