Normally, the VOLUME DAY/NIGHT switch is always left in the DAY

position.

However, if local ordinances require quieter nighttime operation of the menu

sign, move the VOLUME DAY/NIGHT switch to the NIGHT position.

If the system has an optional monitor speaker, adjust its volume using the

following procedure:

1. With the base station turned ON, insert a small straight–blade screwdriver

into the MONITOR VOLUME access hole. See Figure 19.

2. Turn the volume control clockwise to increase the volume or

counterclockwise to decrease it.
