Each field will step through the available frequencies in
a different increment. The increments are also different
in the 25 kHz mode from the 100 kHz mode.

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.
About Overlapping Frequency Bands
When two frequency bands overlap, it is possible to
select the same frequency at the upper end of one and
the lower end of the other. While the frequency will be
the same, the pilot tones will be different, as indicated
by the hex codes that appear.
In the following examples, the frequency is set to
494.500 MHz, but one is in band 470 and the other in
band 19. This is done intentionally to maintain compat-
ibility with receivers that tune across a single band. The
band number and hex code must match the receiver to
enable the correct pilot tone.
