Portable and mobile RF equipment should be used
no closer to any part of drsplus, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1.17√P
d = 1.17√P 80MHz to 800MHz d = 1.17√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).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic sight survey
a
,
should be less than the compliance level in each
frequency range
b
Interference may occur in the vicinity of equipment
marked with the following symbol.
NOTE 1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflections 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 broadcasts and TV broadcasts 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 drsplus is used exceeds the applicable RF compliance level above, drsplus should
be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orientating or relocating drsplus.
b
Over the frequency range 150Khz to 80MHz, field strengths should be less than 3V/m.

During application of the test stimulus, any temporary cessation or
interruption of the intended operation remains within acceptable limits.
