WARNING
The WTU-518 is a class-A device. In residential areas, the user may be requested to take appropriate
measures in the event of RF interference caused by this device.
WARNING
The WTU-518 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:
𝐸 =
30 𝑃 𝐺
𝑑
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
band
P*G
E at 20cm
