Program LPA-Series Volume
The LPA-Series receiver can be field programmed for any volume level between 05-99% by entering the volume
level as a 2-digit code. The LPA receiver is set from the factory with a 50% volume setting. If your PA amplifier
has independant volume control you should not have to adjust the LPA receiver volume. If there is no volume
control, or if the PA amplifier volume control is pre-set for background music, you can adjust the input level to the
PA amplifier by adjusting the LPA receiver volume. Field programming 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 LPA-U450 for 25% Speaker Volume Level.
1. Press and HOLD the PROGRAM button (See LPA-Series 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.
2. Release the PROGRAM 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.
3. 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.
4. 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.
5. 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.
6. 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 LPA-Series receiver will exit program mode automatically after 30 seconds if no
program entries are attempted.
IMPORTANT NOTE: Volume settings below 10% are entered as a 2-digit code with a first digit “0”.
Checking the Current Volume Setting
To readout the current volume setting, follow the instructions above and enter a
volume setting code “00”. When you press the
ENTER button the radio will
immediately begin to display the 2-digit volume setting; with each digit separated by
a hyphen.
