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.
