Guidance and manufacturer's declaration -
electromagnetic immunity
Table 204
The REM 3000 is intended for use in the electromagnetic environment specified below.
The customer or the user of the REM 3000 should assure that it is used in such an environment.

3 V rms
3 V/m
Portable and mobile RF communication
equipment should be used no closer to any
part of the REM 3000, including cables, than
the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance

80 MHz to 800 MHz
Conducted RF
IEC 61000-4-6 3 V rms
150kHz to 80MHz

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 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:
Note1 : At 80MHz and 800MHz, the higher frequency range applies.
Note2 : 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 REM 3000 is used exceeds the applicable RF
compliance level above, the REM 3000 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the REM 3000.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
