For transmitters rated at a maximum output power not
listed above, the recommended separation distance
d in meters (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: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
Proprietary Inductive Linkage between Sound
Processor and Cochlear Implant
The external headpiece and implant are an induction
coupled system. The cochlear implant induction link
behaves as a weakly coupled transformer rather than
as radio transmitter. Power is provided to the implant
