Dolomite Step Up®
Portable and mobile RF communications
equipment should be used no closer to any
part of the product including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance:
Conducted RF
IEC 61000-4-6
3 V
0,150 - 80 MHz
3 V
Radiated RF
IEC 61000-4-3
3 V/m
80 - 800 MHz
3 V/m 80 - 800 MHz
[Requirements
according to
EN12182:2012,
subclause 7.3)
20 V/m
800 - 2700 MHz
20 V/m 800 – 2700 MHz
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).
b
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:
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 theoretically predicted 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 this product is used, exceeds the applicable RF compliance level above, the
product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the product.
b Over the frequency range 0,15 - 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment
and this product
This product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
user of the product can prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and this product as recommended below, according to the maximum
output power of the communications equipment.
Separation distance according to frequency of transmitter [m]

[W]
0,150 - 80 MHz 80 - 800 MHz c 800 – 2700 MHz
0,01 0,12 0,12 0,04
0,1 0,37 0,37 0,11

10 3,69 3,69 1,11
100 11,67 11,67 3,50
c At 80 MHz and 800 MHz, the higher frequency range applies.
For transmitters rated at a maximum output power not listed above, the recommended separation, distance d in metres (m)
can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manufacturer.
