Electromagnetic environment - guidance
The unit uses high frequency energy exclusive for its internal function. From
there the high frequency emission is very low and it is improbable, that other
electronical devices are being disturbed.
The unit is determined for the usage in all facilities including living areas and
such, which are directly connected to a public power supply that supplies
also buildings which are used for living purposes.
Electromagnetic environment - guidance
Floors should be wood, concrete or ceramic tile. If floors
are covered with synthetic material, the relative humidity
should be at least 30%.
d= 1.17 · root(P/W) for 80 MHz to 800 MHz
d= 2.33 · root(P/W) for 80 MHz to 2.5 GHz
with P as the maximum of rated power of the transmitter
in watt according to the transmitter manufacturer and d is
the recommended separation distance in meters (m).
The field strength in each frequency of stationary radio
transmitters should be - in accordance with a site survey
- less than the compliance level.
In the vicinity of equipment that is marked with the logo
„Non-ionizing radiation", disruptions are possible.
