10.4 Recommended safe distance between portable and mobile HF
telecommunications equipment and the STERIclave B
The STERIclave B is intended for use in an electromagnetic environment in which
HF disturbances are controlled. The customer or the user of the STERIclave B can
help prevent electromagnetic disturbances by maintaining the minimum distance
between portable and mobile HF telecommunications devices (transmitters) and the
STERIclave B depending on the output of the communication device as indicated
below.

For transmitters whose maximum rated power is not in the above table, the recom‐
mended safe distance d in meters (m) can be calculated using the equation for the
respective gap, where P is the maximum rated power of the transmitter in Watts (W)
according to the manufacturer's information.
Comment 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Comment 2: These guidelines may not be applicable in every case. The spread of
electromagnetic waves is absorbed and reflected by buildings, objects and people.
