The footswitch controls work as follows:
SCAN: Pressing the footswitch will start and stop the SCAN mode (same as manually pressing
the front panel SCAN button).
CHANNEL: Pressing the footswitch will change the channel from A to B or vice versa.
RANGE: Pressing the footswitch will change to the range set when the mode is selected (i.e.,
set the range to 3V, 10K, 200Hz, select footswitch RANGE mode; pressing the footswitch
will automatically change the Tracker to this range). This is useful for changing to a favorite
range by simply pressing the footswitch.
