Audio Level (Page/Music) LEDs 

The Audio Level LEDs indicate the audio level input for the paging and music 
signals. Low (yellow) indicates a low audio level, Good (green) indicates a good 
audio level, and Clip (red) indicates am audio level that is too high, and clipping 
is occurring. 

Input Page Volume potentiometer 

The Input Page Volume potentiometer allows the page input to be adjusted to 
maintain a good page level indicated by a green LED for the Audio level LEDs. 
Adjustments can be made by a small flat blade screwdriver.  The potentiometer 
is a single-turn potentiometer.  Turning the potentiometer clockwise increases the 
input page signal while counterclockwise decreases the input page signal.
