Operating Instructions
Power Up and Boot Sequence
Simultaneously press and hold the AUDIO and FREQ 
buttons until the startup count is completed. The 
screen will display a count from 1 to 3 as the unit boots 
up, then it switches to the Audio screen. As the unit 
turns on, the Modulation LEDs and PWR LED all glow 
red, then green, and then revert to normal operation.
The LCD displays a boot sequence which consists of 
four screens ending with the audio screen similar to 
this example:
  •  Company name:  Lectro
  •  Frequency block/Firmware Ver.:  b22r2.4
  •  Power level:  Pr 100
  •  Compatibility mode:  CP IFB
  •  Audio (Input gain):  Aud 22
Power Down
Simultaneously press and 
hold the AUDIO and FREQ 
buttons while observing that 
the word “OFF” appears in the LCD along with a counter. 
The screen will display a countdown from 3 to 1 and the 
unit will then turn off.
Note: If the AUDIO and FREQ buttons are 
released before the LCD goes blank at the end of 
the countdown, the unit will not turn off. Instead, 
it will stay energized and the display will return to 
the previous screen.
Standby Mode
With the unit off, quickly 
press both AUDIO and 
FREQ buttons, and release 
before counter reaches “0” to enter the “standby” 
mode. In this mode the RF output is turned off so 
adjustments can be made without interfering with other 
systems operating in the same location. The LCD 
displays rf OFF to remind you that the unit is not 
transmitting.
Use the AUDIO and FREQ buttons to access the vari-
ous setup screens. When the adjustments are com-
plete, press both the AUDIO and FREQ buttons briefly 
to save the settings and turn the unit off.
Lock/Unlock the Keypad
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.
