If my memory serves me right, the 3-position switch is: OFF, ON(FAST
RESPONSE), SLOW RESPONSE. One pot controls the volume, and the other
controls the threshold for lift.

Here is a picture of an older Cambridge vario:

The control on the left has two pots and a 3-position switch. The pots
seem
to control audio volume and sensitivity, but I'm not sure about that. The
switch seems to control response, but I am also not sure about that.

Can anyone shed some light on this?

Thanks.
