Electromagnetic environment - guidance
The device uses RF energy only for its internal
function. Therefore, its RF emissions are very
low and are not likely to cause any interference in
nearby electronic equipment.
The device is suitable for use in all
establishments, including domestic
establishments and those directly connected to
the public low-voltage power supply network that
supplies buildings used for domestic purposes.
Compliance Electromagnetic environment -
level guidance
±6 kV contact Floors should be wood, concrete or
ceramic tile. If fl oors are covered with
±8 kV air synthetic material, the relative humidity
should be at least 30%.
