INSTALLATION NOTES
■ Installation notes
The installation of this equipment should be made in such a
manner as to respect the EC recommended electromagnetic
field exposure limits (1999/519/EC).
The maximum RF power available from this device is 25
watts. The antenna should be installed as high as possible
for maximum efficiency and that this installation height should
be at least 5 meters above ground (or accessible) level. In the
case where an antenna cannot be installed at a reasonable
height, then the transmitter should neither be continuously op-
erated for long periods if any person is within 5 meters of the
antenna, nor operated at all if any person is touching the an-
tenna.
In all cases any possible risk depends on the transmitter
being activated for long periods. (actual recommendation lim-
its are specified as an average of 6 minutes) Normally the
transmitter is not active for long periods of time. Some radio li-
censes will require that a timer circuit automatically cuts the
transmitter after 1–2 minutes etc.
Similarly some types of transmitter, SSB, CW, AM, etc. have a
lower ‘average’ output power and the perceived risk is even
lower.
