Helpful Features on Receivers
To aid in finding clear frequencies, several Lectrosonics
receivers offer a SmartTune feature that scans the tun-
ing range of the receiver and displays a graphical report
that shows where RF signals are present at different
levels, and areas where there is little or no RF energy
present. The software then automatically selects the
best channel for operation.

Lectrosonics receivers equipped with an IR Sync func-
tion allow the receiver to set frequency, step size and
compatibility modes on the transmitter via an infrared
link between the two units.
