Recommended Separation Distances Between
Portable and Mobile Rf Communications Equipment and the POC-621-12 Series
Device
The POC-621-12 series device is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the POC-621-
12 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the POC-
621-12 series device as 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 sep-
aration distance d in metres (m) can be estimated using the equation applicable to the fre-
quency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, 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.
