Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The Genesis DM is intended for use in the electromagnetic environment specified below. The customer
or the user of the Genesis DM 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 Genesis DM, including cables, than
the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.

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.
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, and electromagnetic site survey should be considered. If the measured field strength in the location in which the Genesis
DM is used exceeds the applicable RF compliance level above, the Genesis DM should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Genesis DM.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
