•
Buildings of all types and vegetation.
• Conductive components that could distort and weaken the field are
located in the vicinity of the devices or on or near to the transmission
path.
•
The distance from the transmitter or receiver to conductive surfaces
or objects (or to floors or human bodies) has an effect on the radiation
characteristics of the antennas and, as a result, on the range.
•
In urban areas, broadband interference can reach levels which reduce
the signal to noise ratio and, as a consequence, the range.
• PCs with insufficient shielding can radiate to receivers, thus reducing
the range.
eQ-3 AG hereby declares that this device complies with the essential
requirements and other relevant regulations of Directive 1999/5/EC. You
