ELECTROMAGNETIC ENVIRONMENT -GUIDANCE
The Demi uses RF energy only for its internal function. Therefore, its RF emissions are very
Plus
low and not likely to cause any interference in nearby electronic equipment.
The Demi Plus is suitable for use in all establishments, including domestic establishments and
those directly connected to the public low-voltage power distribution network that supplies
buildings or for domestic 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%.
Mains power quality should be that of a typical commercial or hospital environment.
Mains power quality should be that of a typical commercial or hospital environment.
Mains power quality should be that of a typical commercial or hospital environment.
Note: UT is the AC mains voltage prior to the application of the test level.
Power frequency magnetic field should be at levels characteristic of a typical commercial or
hospital environment.
Portable and mobile RF communications equipment should be used no closer to any part of
the Demi Plus including the power supply and cable than the recommended separation distances
calculated from the equation applicable to the frequency of the transmitter.
Field strength from fixed RF transmitters, as determined by an electromagnetic site survey,
should be less than the compliance level in each frequency range
