Portable and mobile RF communications
equipment should be used no closer to any part
of the DU3035 device, including cables, than the
recommended seperation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended seperation distance:
d=1.2√P
d=1.2√P , 80MHz to 800MHz
d=2.3√P , 800MHz to 2.5GHz
where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and
d
is the
recommended separation
distance in meters (m).

Interference may occur in
the vicinity of equipment marked
with the following symbol:
NOTE I: At 80 MHz ends 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.
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 device is used exceeds the applicable RF compliance level above, should be
observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3
