About
When changes are locked, several controls and actions 
can still be used:
•  Settings can still be unlocked
•  Menus can still be browsed
•  When locked, POWER CAN ONLY BE TURNED 
OFF by removing the batteries.
Main Window Indicators
The Main Window displays the block number, Standby 
or Operating mode, operating frequency, audio level, 
battery status and programmable switch function. When 
the frequency step size is set at 100 kHz, the LCD will 
look like the following.

When the frequency step size is set to 25 kHz, the hex 
number will appear smaller and may include a fraction.

Fraction
1/4 = .025 MHz
1/2 = .050 MHz
3/4 = .075 MHz
Changing the step size never changes the frequency. 
It only changes the way the user interface works. If the 
frequency is set to a fractional increment between even 
100 kHz steps and the step size is changed to 100 kHz, 
the hex code will be replaced by two asterisks on the 
main screen and the frequency screen.

Connecting the Signal Source
Microphones, line level audio sources, and instruments 
can be used with the transmitter. Refer to the section 
entitled Input Jack Wiring for Different Sources for 
details on the correct wiring for line level sources and 
microphones to take full advantage of the Servo Bias 
circuitry.
Turning Control Panel LEDs ON/OFF
From the main menu screen, a quick press of the UP 
arrow button turns the control panel LEDs on. A quick 
press of the DOWN arrow button turns them off. The 
buttons will be disabled if the LOCKED option is select-
ed in the Power Button menu.
The control panel LEDs can also be turned on and off 
with the LED Off option in the Power Button menu.
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.
