RECALL “R” PISTON
The “R” or Recall piston recalls the last registration setting prior to using any General or
Divisional piston. For example;
Press a General or Divisional piston/toe stud. The stop registration programmed on that
particular piston/toe stud will appear.
Manually register additional stops to the current stop registration.
Now, press a different General or Divisional piston/toe stud. The stop registration
programmed on that particular piston/toe stud will appear.
Press the “R” piston. The previous stop registration, including those stops registered
manually, will re-appear.
What happens is the capture system takes a “snapshot” of the current stop registration and stores
it within the Recall piston memory before it actually changes to the new stop registration
selected. Then, when the “R” piston is pressed, the capture system “recalls” the previous
registration stored before the last piston/toe stud selection was made.
REVERISBLE PISTONS
The Q286 and HII-86 contain several reversible type piston buttons. Reversible pistons are those
which “toggle” a specific stop on or off when pressed. If a stop assigned to a reversible piston is
on, pressing the associated reversible piston will turn the stop off. The same is true in reverse, if
the stop is off, pressing the associated reversible piston will turn the stop on.
