Guidance and manufacturer's declaration - electromagnetic emissions
The Model MKC-750UHD is intended for use in the electromagnetic environment specified below.
The customer or the user of the Model MKC-750UHD should assure that it is used in such an
environment.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range apply.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation 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 environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength In the location in which the MODEL MKC-750UHD Is used exceeds the applicable RF
compliance level above, the MODEL MKC-750UHD should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the MODEL MKC-750UHD.
*
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
