Technical data on electromagnetic compatibility (EMC instruc-
tions) in table format are included with the device. It can also
be ordered from PARI GmbH or downloaded from the internet
at www.pari.de/en/products under "Technical Data" on the re-
spective product page.
6.4 Recommended safety distances
Recommended safety distances between portable and mobile
high-frequency (HF) telecommunication devices and the PARI
compressor:
The PARI compressor is intended for operation in an electro-
magnetic environment in which radiated HF transients are
monitored. The user can help to prevent electromagnetic inter-
ference by observing the minimum safety distances between
portable and mobile HF communication equipment (transmit-
ters) and the PARI compressor, as recommended below in ac-
cordance with the maximum output power of the communica-
tion device.
Safety distance depending on transmitting frequency:
Rated power of
the transmitter
150 kHz to
80 MHz
D = (3.5/3) ×
SQRT(P)
80 MHz to
800 MHz
D = (3.5/3) ×
SQRT(P)
800 MHz to
2.5 GHz
D = (7/3) ×
SQRT(P)
0.01 W
0.2 m
0.2 m
0.3 m
0.1 W
0.4 m
0.4 m
0.8 m
1 W
1.2 m
1.2 m
2.3 m
10 W
3.8 m
3.8 m
7.3 m
100 W
12 m
12 m
23 m
For transmitters whose rated power does not appear in the
table above, the safety distance can be calculated using the
equation associated with the respective column, where "P" is
the rated power of the transmitter in Watt (W) according to the
information supplied by the device manufacturer.
