the button in pressed, the text and the perimeter will illuminate.
Some buttons are part of groups, and groups might only allow a single button to be pressed at a time. The
sample rate buttons are examples. When you press a button that is part of a group that only permits a single
selection, the button that is currently illuminated will momentarily flash to signify it is turning off in response
to your request to change modes.
QA40x Basic Controls
The QA402 and QA403 application, also known as the QA40x application, is shown below:
On the left side of the application is the CONTROL region. On the right side of the application is the SPECTRUM
or GRAPH region.
In the control region, you can use the mouse wheel to scroll the control set up and down. On a laptop, this can
usually be done by using two fingers on the track pad (check with your laptop vendor to see how they
recommend emulating a mouse wheel if the two finger technique doesn’t work).
Alternately, the Page Up and
Page Down buttons will scroll the control region, as will the up and down arrow keys.
