The wireless speaker can be field programmed for any volume level between 05-99% by entering the volume level 
as a 2-digit code.  Field programming Speaker Volume Level sets both the voice and the pre-announce tone 
volume levels.  The PC programmer is required for independent programming of the voice and the pre-announce 
tone volume.   

In our example we will program an LM-U450 for 25% Speaker Volume Level.  The Loudmouth

™

 is set from the 

factory with a 50% volume setting. 

 

1. Refer 

to 

Section 1.5 - Determine the volume setting 

and write down the desired volume. 

2. Press 

and 

HOLD the PROGRAM button (See 

Loudmouth

™

 receiver assembly

 on page 2 

for location). A "P" will appear on the program display as you enter program mode and the 
radio will beep rapidly. 

3. Release 

the 

 

button after the beeping has stopped. The radio will emit a triple 

beep indicating that the radio is in program mode and a hyphen will appear on the program 
display. 

4.  Scroll to the character “U” by clicking the PROGRAM

 

button until the program display 

shows the correct character. Pause—the radio will sound a low tone and show a hyphen 
across the center of the display to indicate that it is ready to accept the first digit of the 
volume setting.   

5.  Enter the 1

st

 digit of the volume setting by clicking the PROGRAM

 

button until the program 

display shows the desired number. Pause—the radio will sound a low tone and show a 
hyphen across the center of the display to indicate that it is ready to accept the next digit. 

6.  Enter the 2

nd

 digit of the volume setting by clicking the PROGRAM

 

button until the program 

display shows the desired number. Pause—the radio sounds a low tone and will show a 
hyphen across the center of the display to indicate that it is ready to accept the next digit. 

7.  Press and release the ENTER button to save your programming. A triple beep will sound to 

indicate that programming was successful and a hyphen will appear on the program 
display.  The radio is now ready for another program entry. 

 

NOTE:  An error tone will sound if you attempt to save an incorrect code, an "E" will appear 
on the display.  Check the digits you are attempting to enter, then re-enter.   

7. 

Once you have made your final program entry, press the ENTER button a final time to exit 
programming mode.  The Program display will be blank and the radio will be ready for use.  
The Loudmouth

™

 will exit program mode automatically after 30 seconds if no program 

entries are attempted.
