3.6.3 Working clearances
Recommended working clearances
between portable and mobile HF
communication devices and the UNIT
The UNIT is intended for operation in an electromagnetic environment,
where radiated RF interference is checked. The customer or the user of
the UNIT can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the UNIT - depending on the maximum
output power of the communication device, as shown below.
The recommended safety distance d in meters (m) can be determined for
transmitters, whose maximum power rating is not specified in the above
table, using the equation that belongs to the corresponding column,
wherein P is the maximum power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
Note 1
The higher frequency range applies at 80 MHz and 800 MHz.
Note 2
These guidelines may not apply in all cases. The propagation of
electromagnetic waves is influenced by their absorption and reflection by
buildings, objects and persons.
