Status/Page On LEDs 

The Status LED indicates that the internal microprocessor is functioning 

normally. 

The Page On LED indicates an active page is in progress. 

Audio Level (Page/Music) LEDs 

The Audio Level LEDs indicate the audio level input for the paging signal. 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.
