The keys are inoperable as long as operation of the mechanism is continued.
When driving the CAMMOTOR in 31 → 30 → 10 (in REV direction),
*
the elevation position must be at the EJECT/LOAD position (the top position).
Note 1:
When the elevation is situated at the Note 1 position, move of any motor
other than the REV is disabled.
Note 2:
Before performing the elevation, make sure that the CAM SW (switch) is
set to a position between 22 and 20.
As a rule, driving of the ELV MOTOR must be started immediately after
the CAMSW indication has changed from 22 to 20.
