Portable and mobile RF
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 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.
The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz;
13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
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 DDU-100 is used exceeds the
applicable RF compliance level above, the DDU-100 should be observed to verify normal operation. If abnormal
performance is observed additional measures may be necessary, such as reorienting or relocating the DDU-100.
