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:
• Frequency block/
Firmware Ver.:
• Power level:
• Compatibility mode:
• Audio (Input gain):
Power Down
Note: If the AUDIO and FREQ buttons are released before the LCD goes blank
at the end of the countdown, the unit will stay energized and the display will
return to the previous screen.
Standby Mode
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 various setup screens. When the
adjustments are complete, press the AUDIO and FREQ buttons together 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 buttons can still be used to display cur-
rent 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 batteries or unlock it via
the RM remote control.
