communications equipment should
be used no closer to any part of
the DDU-100, including cables,
than necessary. The recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter is
shown in the following table.
Interference may occur in the
vicinity of equipment marked with
the following symbol:

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xedRFtransmitters,anelectromagneticsitesurvey

performance is observed additional measures may be necessary, such as reorienting or relocating the DDU-100.
