❏ Cautions

*
*
During the mech operation, each key input is ignored.
When the ELV position is '11'(*Note 1), the other motors cannot be moved.
For elevation, the CAMSW should be at the state *Note 2 as shown above.
Basically, right after the display for the CAM SW changes from 22 to 20, drive the ELV MOTOR.)
When the CAM MOTOR is moved in the REV mode (31 → 30 → 10),
the Elevation should be at the EJECT/LOAD position.
