Guidelines and manufacturer's declaration – Electromagnetic immunity
The PremoPort
Four
device is intended to be operated in an electromagnetic
environment as indicated below. The customer or user of the PremoPort
Four
should
ensure that it is used in such an environment.

Portable and mobile radio equipment
should not be used at a distance
away from the PremoPort
Four
,
including the cables, that is less than
the recommended safety distance
which is calculated according to the
equation applicable to the
transmission frequency.
Recommended safety distance:
d= [3.5 / V1] √P
d= 1.17 √P for 80 MHz to 800 MHz
d= 2.33 √P for 800 MHz to 2.5 GHz
with P as the rated output of the
transmitter in watts (w) according to
the information of the manufacturer of
the transmitter and d as the
recommended safety distance in
meters (m).
At all frequencies, the field strength of
stationary radio transmitters should
be less than the compliance level
b
according to on-site testing
a
.
In the environment of devices which
bear the following symbols,
interferences are possible:
NOTE 1 At 80 Hz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of
electromagnetic variables is influenced by absorption and reflection from buildings,
objects and people.
