Speaker Volume Control
You can adjust the volume of the modem’s phone-line monitor speaker with a volume control knob,
located on the back of the modem next to the RS-232C connector (see Figure 9-1 for location). Turn
the knob clockwise to increase the modem's volume and counterclockwise to decrease speaker
volume.
