Guidance and manufacturer´s declaration – electromagnetic immunity
The MACH LED 500DF is intended for use in the electromagnetic environment specified below. The customer
or the user of the MACH LED 500DF should assure that it is used in such an environment.

Portable and mobile RF communications equipment should
be used no closer to any part of the MACH LED 500DF,
including cables, than the recommended separation dis-
tance calculated from the equation applicable to the fre-
quency of the transmitter.

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 500DF is used exceeds the applicable RF compliance level above, the MACH LED 500DF 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 500DF.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
