land, remove the soldering quickly with a soldering iron whose
insulation resistance is larger than 10M
.

6-1. GENERAL
Note:Note on repairing the Base Unit Ass'y.
When operating or repairing the unit, grounding is required to pre-
vent damage caused by static electricity and is as follows:
1. Grounding for the human body
Besure to wear a wrist-strap for grounding (with impedance lower
than 108
) whose other end is ground. The strap works to drain
away the static electricity build-up on the human body.
2. Grounding for the work table
Be sure to lay a conductive sheet (with impedance lower than 108
)
on the table, sure as a sheet of copper, which is ground.
3. As static electricity build-up on clothes does not drain away, be
careful not to let your clothes touch the unit.

5. Do not apply excessive force to the when wiping. Optical device
is structured by very sensitive mechanism parts.The lens holding
mechanism may have damage if apply excessive force.
Cotton Swab
Optical Pick-up Cover
Wipe the surface of an object lens with
a spiral from the center to outside.

[Disc Chucking/Unchucking Method]
1. Connect the controller.
2. Load a disc directly into the drive with your hand.
3. Press the EJECT button of the controller. The LEDs will go off in the order of red and green.
When both LEDs go off, it means that both discs have been chucked.
4. To eject the disc, press the EJECT button again.
5. The LEDs light up in the order of green and red. When both LEDs light up, it means that the discs have been unchucked.
NOTE :
If the LEDs remain lit or off even when chucking/unchucking is performed, S51 (red:UNCHUCK), S52 (green:CHUCK) of the CDM-47
LDSW board may be improperly connected.
[Single-Operation of CDM-47]
1. Chuck the disc beforehand.
2. Set the COMMAND SW of the controller to the test mode.
