Recommended separation distances between portable and
mobile RF communications equipment and the Chorus
Sound Processor
The recommended separation distance between the Chorus
Sound Processor and an RF transmitter is calculated based
on the maximum RF transmitter output as determined by an
electromagnetic site survey. The following equations are used
to compute the separation distance in meters based on the
transmitter power output in Watts.
