portable and mobile RF communications equipment and the KOWA
The KOWA
is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of the KOWA
minimum distance between portable and mobile RF communications equipment (transmitters) and the KOWA
recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m)
can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1
80MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
Recommended separation distances between
