4)  Press either AUDIO or FREQ button to select the 
power setting screen and use the Up and Down 
down arrows to select the desired level of power.
5)  Simultaneously press the AUDIO and FREQ but-
tons to exit this mode and turn off the power.
Audio Screen
The Audio screen is used to 
adjust input gain from 0 to +44 
dB, and the low frequency 
roll-off from 35 to 150 Hz. 
Repeatedly pressing the 
AUDIO button toggles back 
and forth between the two 
displays. Press and hold the AUDIO button and use the 
Up and Down arrows to make adjustments.
Frequency Screen
The Frequency Screen 
displays the operating 
frequency in MHz or as a 
two-digit hexadecimal 
number that corresponds to 
the equivalent Lectrosonics 
Frequency Switch Setting. 
Repeatedly pressing the 
FREQ button toggles between the two displays. Press 
and hold the FREQ button and use the Up and Down 
arrows to select the frequency. 
Lock/Unlock Screen
Simultaneously pressing 
and holding both the Up and 
Down arrow buttons during 
normal operation starts the 
Lock 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 buttons 
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. Remove the batteries to 
unlock the control panel.
Important: 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 Operation
Remote Control Screens
The transmitters can be 
configured to respond to 
signals from the LectroRM 
app or to ignore them. This 
setting is accessed by 
holding Down arrow button 
while powering the transmit-
ter on. Use the arrow keys to 
toggle between “rc on” (remote control on) and “rc 
oFF” (remote control off). The default setting is “rc on.”
If a remote control signal is detected but the transmitter 
is set to “rc oFF”, the message “rc oFF” will be dis-
played briefly on the transmitter’s LCD, to confirm that a 
valid signal was received, but that the transmitter is not 
configured to respond to it. 
Remote functions available are:
•  Tx Input Gain
• Sleep/Unsleep
• Lock/Unlock
• Frequency
•  Tuning in 25 kHz steps
•  Changing the low frequency roll-off setting
•  Turning on/off the PWR and Audio LEDs
•  Gain up/down functions 
In sleep mode, the transmitter uses only 20% of the 
normal amount of battery drain. Sleep mode can only be 
invoked with the remote control, and can only be revoked 
with the remote control or by removing the battery. When 
in the sleep mode, the PWR LED blinks green every few 
seconds to indicate that the transmitter is asleep and not 
turned off.
NOTE: See LectroRM for more information.
