Warning: If the wireless system is connected
to a live sound system, turn the sound system
level down first to avoid severe feedback.
1) Position the microphone in the location where it will
be used in actual operation.
2) Place the transmitter in the “standby” mode or turn
it on for normal use.
3) While speaking or singing into the microphone at
the same voice level that will be used, observe
the LEDs on the control panel. Hold the AUDIO
button and press the UP or DOWN arrow buttons
to adjust the gain until the -20 LED flickers red on
louder peaks. This LED turns red at the instant
full modulation takes place and the very onset of
limiting. The red color does not indicate overload
or clipping.
-20 LED should flicker
red during louder peaks
in the audio
This will maximize the audio signal to noise ratio of the
system and provide plenty of headroom (limiter range)
to handle even louder peaks that could occur.
If the unit was set up in “standby” mode, it will be neces-
sary to turn the transmitter off, then power it up again in
normal operation so the RF output will be on. Then the
other components in the sound or recording system can
be adjusted.
Frequency Selection
The frequency can be displayed either in MHz or as a
two-digit hexadecimal number and can be set in the
Standby Mode or when the transmitter is powered up
in the normal operating mode.
The hexadecimal numbering system is unique to
Lectrosonics where two alphanumeric characters cor-
respond to the left and right switch settings on earlier
analog transmitters that had mechanical rotary switch-
es to adjust frequency.
1) Press the FREQ button to select either the MHZ
screen or the hexadecimal screen.
2) While holding the FREQ button, use the Up or
Down arrow buttons to move the operating fre-
quency up or down in 100 kHz increments from
the current setting.
Lock/Unlock Screens
The control panel buttons can be locked out to avoid
inadvertent changes in the settings or turning the
unit off unintentionally. Simultaneously pressing and
holding both the UP and DOWN arrow buttons during
normal operation starts a countdown timer.
The timer starts at three and counts down to zero.
When the timer reaches zero, the transmitter’s controls
are locked.
With the controls locked, the AUDIO and FREQ but-
tons can still be used to display current settings. Any
attempt to change a setting by pressing either the Up
or Down arrow button will result in an on-screen Loc
reminder that the controls are locked.
Once the transmitter is locked, it cannot be unlocked
or powered off using the buttons. The only ways to
unlock a locked transmitter are to remove the battery
or unlock it via the RM remote control.
Remote Control Enable/Disable and
Configuring Power Restore
These two settings are made with a screen that is ac-
cessed with a special button sequence.
Then press the AUDIO and FREQ
buttons at the same time
Hold the DOWN
arrow button
The remote control screen setup will appear first.
When either the AUDIO or FREQ button is pressed,
the screen will switch to the power restore setup
screen. Pressing either button again will return the unit
to the “standby” mode with the RF output turned off.
To access these screens again, turn the unit off and
press the three buttons as shown above to start over.
