23 POC-621 Series User Manual
Chapter 2 System Setup
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.
Guidance and manufacturer’s declaration – electromagnetic immunity
