Operating Procedures:
1)
Turn on the Mechanism Test Mode.
2)
Select the motor to be driven
using the [1] to [4] keys.
3)
Press the [SEEK/SKIP+] or [SEEK/SKIP-] in this
state to drive the selected motor.
Operating Procedures for Ejecting a Clamped Disc
1
Select CAMMOTOR using [1], then press the [SEEK/SKIP-] while the disc is being clamped (CAMSW state is 32).
The CAMSW status indication sequentially changes through 32→33→23→22.
2
When the disc to be ejected is not identical with the disc being clamped, select the [2 ] ELVMOTOR in the vicinity of where
the display changes from 22 to 20, then match the elevation to the disc to be ejected according to the following procedures:
After selecting ELVMOTOR, lower the elevation until the ELV position display becomes 01 (1st disc) using the [SEEK/SKIP-].
Drive the elevation up until the display is changed to 10 using the [SEEK/SKIP+] . This is the elevation where the second disk is situated.
The next display of 10 tells you the elevation of the 3rd disc. Repeating this operation allows you to establish an elevation
matching each disc. (When the elevation is driven from the 1st through 6th disc, the status display changes as
01→11→10→11→10→11→10→11→10→11→10.)
(When the disc to be ejected coincides with the disc being clamped, the above operations are not necessary.)
3
Select the [1] CAMMOTOR and then, using the [SEEK/SKIP-], drive it until the display changes from 20 (or 22) to 21 and 31.
4
Select the [2] ELVMOTOR, then drive the tray of the disc to be ejected up to the EJECT/LOAD position (using the [SEEK/SKIP+]).
5
Select the [4] CAM+LOADMOTOR, then drive it in the REV direction until the display changes from 31 to 30 and 10.
The door will open immediately before the display changes to 10 and part of the disc will be pushed out.
6
When 10 is displayed, select the [3] LOADMOTOR, then drive it in REV direction until the disc is completely ejected.

Precautions
* 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.
