The KEY Laser III is intended for use in an electromagnetic environment in which
HF disturbances are controlled. The customer or the user of the KEY Laser III can
help prevent electromagnetic disturbances by maintaining the minimum distance
between portable and mobile HF telecommunications devices (transmitters) and the
KEY Laser III depending on the output of the communication device as indicated
below.
The table shows the necessary safe distance depending on the transmission fre‐
quence in m:

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.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not be applicable in every case. The spread of
electromagnetic waves is absorbed and reflected by buildings, objects and people.
