Guidance and manufacturer’s declaration-electromagnetic immunity
The MBB15K2DM is intended for use in the electromagnetic environment specified below.
The customer or the user of the MBB15K2DM should assure that is used in such and environment.

equipment should be used no closer to any
part of the MBB15K2DM;including cables, than

Interference may occur in the vicinity of
equipment marked with the following symbo
l:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 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 MBB15K2DM is used exceeds the applicable RF
compliance level above, the MBB15K2DM should be observed to verify normal operation. If abnormal performance is
observed, additional measures my be necessary, such as re-orienting or relocating the MBB15K2DM.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.
