Optimum range will be realized if the system is set 
to a frequency where few or no other RF signals are 
present (a “clear” frequency). The receiver can select a 
clear frequency automatically with Smart Tune
TM
.
Navigate to Smart Tune in the LCD menu and press 
MENU/SEL to start the process. Select the desired

the scan.

Cursor scrolls 
across screen 
during scanning
When the scan is complete a screen will appear briefly 
to display the frequency chosen by Smart Tune, and 
then it will change to IR Sync. If you are using a Lec-
trosonics transmitter that has an IR port, the settings 
can be transferred from the receiver to the transmitter 
in a few seconds with a single button.
As shown below, IR Sync will prompt you to place 
the receiver and transmitter close to one another and 
press the UP arrow button. Hold the units within two 
feet or so apart with the IR ports facing each other, 
then press the button. The transmitter LCD will display 
a message confirming the receipt of the settings.
NOTE: IR sync transfers the settings for 
frequency, step size and compatibility mode.
If you are not using a Lectrosonics transmitter with an 
IR port, simply return to the Main Window and observe 
the frequency that was chosen by Smart Tune. Make 
sure the compatibility mode selected in the receiver is 
correct for the transmitter in use. Then set the transmit-
ter on the frequency chosen by Smart Tune.
4b) Find a Clear Frequency Manually
Navigate to RF Scan on the menu and press MENU/
SEL to start the scanning. The LCD will display a 
marker that travels across the screen as a graphical 
image of the RF energy appears. The marker will wrap 
back to the beginning and continue to repeat.
