should be used no closer to
any part of the StimRouter
system, including cables, than

distance calculated from the
equation applicable to the
frequency of the transmitter.

output power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation
distance in meters (m).
Field strengths from fixed RF
