If you also purchased the optional Professional Demodulator, you can select
this demodulator from the Demodulators top bar menu. The basic functions
such as volume control, audio muting and mode selection are identical to
the Standard Demodulator.

For details of the additional functions such as continuous IF bandwidth
adjustment and other special features of the Professional Demodulator refer
to Appendix E - Professional Demodulator.

The Volume control is also located in the Demodulator panel. The volume
can range from 0 (no sound) to 31 (full volume). To enter a value directly,
click on the display and type in the new volume level. The volume can be
also increased or decreased by clicking on the up/down buttons next to the
volume display.

Another convenient way of changing the volume is by using the small slider
button between the up/down buttons.  Place the mouse cursor on it and see
the cursor shape change, to indicate a ‘slider’ type of control.  Hold down the
left mouse button to drag the slider up or down and the volume will change
accordingly.
