Locking a Combination Memory
When shipped from the Rodgers factory, all memory levels are unlocked so that pistons can be
easily changed. If desired, each memory level can be locked individually so that it cannot be
changed.
On instruments with combination action pistons M1, M2, etc., any memory level can be
locked using the following procedure:
1. Press and hold the memory piston (M1, M2, M3, etc.) corresponding to the
memory level you want to lock until the memory bank screen appears. Internal
or Memory Card and (#) Unlocked or (#) Locked appears in the display.
2. If (#) Unlocked appears, go to step 3. If (#) Locked appears, the memory level is
already locked.
3. Turn the Select knob to highlight Unlocked.
4. Rotate the Alpha dial to select Locked. The memory is now locked and that
memory level cannot be changed.
On instruments with the M+ and M- pistons, memory level may be locked using the one
of the following procedures:
1. Use M+ or M- pistons to select the memory level to be locked.
2. Press and hold SET then press and release M+.
3. Turn the Select knob to highlight Unlocked.
4. Rotate the Alpha dial to highlight Locked.
