Guidance and manufacturer's declaration - electromagnetic immunity
The EDR-9000 is intended for use in the electromagnetic environment specified below. The customer or
the user of the EDR-9000 should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the EDR-9000, including
cables,
than the recommended
separation distance calculated
from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d=1.2 root(P)
d=1.2 root (P) 80MHz to 800MHz
d=2.3 root (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
metres(m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site 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 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 EDR-9000 is used exceeds the applicable RF compliance level above, the EDR-
9000 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the EDR-9000.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
