Recommended Safety Distances - Pari 047 Gebrauchsanweisung

Technical data on electromagnetic compatibility (EMC instruc-
tions) in table format are included with the device. These can

ive product page.

6.4 Recommended safety distances

Recommended safety distances between portable and mobile
high-frequency (HF) telecommunication devices and the
device:
The product is intended for operation in an electromagnetic en-
vironment in which radiated HF transients are monitored. The
user can help to prevent electromagnetic interference by ob-
serving the minimum safety distances between portable and
mobile HF communication equipment (transmitters) and the
product, as recommended below in accordance with the max-
imum output power of the communication device.
Safety distance depending on transmitting frequency:

transmitter
0.01 W
0.1 W
1 W
10 W
100 W
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.
