A fraction will appear next to the hex code in the setup
screen and in the main window when the frequency
ends in .025, .050 or .075 MHz.

If the Step Size is 25 kHz with the frequency set be-

changed to 100 kHz, the mismatch will cause the hex
code to display as two asterisks or "x's."

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-
0
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.

Selecting Audio Polarity (Phase)

Audio polarity can be inverted at the transmitter so the
audio can be mixed with other microphones without
comb filtering. The polarity can also be inverted at the
receiver outputs.

Selecting Battery Type

The voltage drop over the life of different batteries var-
ies by type and brand. Be sure to set the correct battery
type for accurate indications and warnings. The menu
offers alkaline or lithium types.

If you are using rechargeable batteries, it is better to
use the timer function on the receiver to monitor the
battery life rather than the indicators on the transmitter.
The timer is available on all Lectrosonics Digital Hybrid
Wireless receivers. Rechargeable batteries maintain
®
a fairly constant voltage across the operating time on
each charge and stop working abruptly, so you will have
little or no warning as they reach the end of operation.
