IMPORTANT INFORMATION REGARDING ELECTRO MAGNETIC COMPATIBILITY EMC
Electromagnetic immunity IEC60601-1-2
Immunity test IEC 60601 Test level Compliance level Electromagnetic environment –guidance
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 sur vey,
*2)
should be less than the compliance level in each frequency range.
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.
*2)
Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless) telephones and land mobile 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 PM601 is used
exceeds the applicable RF compliance level above, the PM601 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the PM601.
