Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

Detection arm
- Clamp operation
When the rack lever in contact with the detection lever is driven by the loading motor, the rack lever engages with the gear to move the clamp UP lever, mechanical lock arm, and mechanical lock lever toward the directions indicated with arrows in Fig. 22. The clamper arm, that was lifted by the clamp UP lever, comes down to clamp disc. The clamp UP lever and mechanical lock lever L move the loading arm apart from the disc. When the mechanical lock lever has moved to a specified position, the system turns the clamp switch to ON to stop the loading motor.

- Mechanical locking
During ejection, two mechanical lock levers slide into the teeth of the frame to resist the mechanical spring and push down the front of floating (chassis) unit. Thus, the system detects the height of disc insertion. During playback, the floating unit is released when the mechanical lock levers move and disengage from the frame teeth.
- Ejection
Disc is ejected by the loading motor rotating in the inverse direction from loading to activate mechanical locking, release clamping, and press the roller. The system stops the loading motor when both phototransistors P2 and P3 in the rear of the rubber roller detect. (Voltage : L)
