Operation steps from CLAMP to EJECT
1
Press the [3] key to select the CAM MOTOR, and drive the CAM MOTOR from the CLAMP position (CAMSW:32) for the REV direction.
The CAMSW display changes as 32→33→23→22.
2
If the disc clamped is not the disc to be ejected, around the shifting point between 22 and 20,
press the [4] key to select the ELV MOTOR and to position the elevation to the disc to be ejected.
After selecting the ELV MOTOR, first be sure to move the Elevation down (in the REV direction) till the ELV position display shows 01 (Disc 1).
When the Elevation is moved upward (in the FWD direction), the first indication of 10 shows the position of Disc 2, and the second indication
of 10 shows that of Disc 3.
Therefore, you can detect the position of the elevation by counting the number of the indication '10'.
(Ex: When the elevation moves from Disc 1 to Disc 6, the display changes as follows:01→11→10→11→10→11→10→11→10→11→10.)
(If the disc to be ejected has been clamped, step 2 is not necessary.)
3
Press the [3] key to select the CAM MOTOR, drive the CAM MOTOR in the REV direction till the indication changes from 20 (or 22)
to the shifting point between 21 and 31.
4
Press the [4] key to select the ELV MOTOR, and move the tray for the disc to be ejected to the EJECT/LOAD position (in the FWD direction).
(When the elevation is positioned at the top after moving in the FWD direction (the indication: 10), this is called the EJECT/LOAD position.)
5
Press the [6] key to select the CAM+LOAD MOTORS, and move the motor in the REV direction until the display changes from 31 to the
shifting point between 30 and 10.
When the display becomes 10, the door opens and the disc is slightly pushed out.
6
When the display becomes 10, press the [5] key to select the LOAD MOTOR. Drive the motor in the REV direction to eject the disc completely.
- Error No. Display
The error mode is turned on if a CD player becomes not playable or is forced to halt due to an error. Cause(s) of an
error will be indicated with numerical characters. The error-number-display function is intended to facilitate the
error analysis and resulting repair work.
