Frequently asked questions

The IOP of the laser pickup is the rated current value shown on the label. It should be in a range of 30 to 60 mA. If the value is large, the pickup will be defective.

We suggest that you use grease FL-955 or equivalent type. Please contact Kanto Chemicals Co. Ltd., 2-7 Kanda Sakuma-cho, Chiyoda-Ku, Tokyo, Japan.

1. Reassemble the Sled Motor with screws F03 (2 pcs.) with a torque of 2.0 kg-cm. Pay attention to the sled motor installing direction. Install it as shown in Fig. 1.9.1. 2. Press fit a new First Gear so that the gap between the chassis surface and the bottom of the First Gear is 0.1 mm. 3. Solder the wires of the Sled Motor to the Traverse P.C.B. Ass'y. 4. Reassemble other removed parts by reversing the removal procedure.

The UD Cam S is used on the left side of the CD Mechanism Ass'y and has projections. The UD Cam is used on the right side of the CD Mechanism Ass'y and has no projections. Note that they move in the opposite direction each other.

The laser diode shorting lands are located on the bottom of the Laser Pickup. They are used to short the laser diode during repair or replacement of the Laser Pickup. Use a soldering iron whose metal part is grounded or a ceramic soldering iron to short the lands.
