Front Panel Setup

Set up the FM-15 ALC as follows:

1.Set the MANUAL LEVEL CONTROL to automatic (Blue Knob) (see Figure 2-1). This allows the FM-15 ALC to calibrate itself.The automatic position will allow the FM-15 ALC to constantly change the paging level to compensate for the changes in noise level in the area being monitored.

2.Check the SPL meter (the Green LED) (see Figure 2-1) for maximum noise level. This is your high noise level reading.

3.Set the MAXIMUM NOISE LEVEL control (Red Knob) (see Figure 2-1) to the average high noise level. If you feel the room noise may actually be louder at some time, move the control up one click to the right (clockwise).

4.The PAGING LEVEL meter (the Red LED paragraph) (see Figure 2-1) indicates the paging level changes that are taking place with dual LEDS.

5.Calibration is complete.
