Guidance and manufacturer´s declaration – electromagnetic immunity
The MACH LED 2MC/SC is intended for use in the electromagnetic environment specified below. The customer
or the user of the MACH LED 2MC/SC 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 MACH LED 2MC/SC
including cables, than the recommended separation dis-
tance calculated from the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance
Pd 17,1
Pd 17,1

Pd 34,2
800 MHz to 2,5 GHz
where p is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufactur-
er and d is the recommended separation distance in metres
(m).
b
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 is affected by absorption and reflection from structures, objects
and people.
a
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 envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in
which the MACH LED 2MC/SC is used exceeds the applicable RF compliance level above, the MACH LED 2MC/SC should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
MACH LED 2MC/SC.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
