Conforms to the essential requirements of the following EEC directives:
R&TTE 1999/5/CE
EMC 2004/108/CE
LV 2006/95/CE
The LRC-508 meets the reference level set by the 1999/519/CE recommendation:
Electric field strength in the far field of a radio frequency point source is calculated as follows:
√30 ∗
∗
With:
E = Electric filed in V/m
P = Maximum average transmit power capability of the radio, in W
G = total Tx gain as a factor, converted from dB
D = distance from the point source, in m
