LASER PRODUCT

THIS COMPACT DISC PLAYER IS CLASSIFIED AS A CLASS 1 LASER PRODUCT.

THE CLASS 1 LASER PRODUCT LABEL IS LOCATED ON THE REAR EXTERIOR.

(3) Soldering Iron to be Used

The soldering iron for use in repair work should be: (1) a ceramic soldering iron, (2) a soldering iron with its metal part grounded, or (3) a soldering iron whose insulation resistance after five minutes of power application is 10 M-ohm or more at 500 VDC. Soldering should be completed promptly, at a soldering iron temperature of 320'max (39 W). A soldering iron heated above this temperature can break down the laser diode.

1.4. Handling the Laser Pickup

In case of repair or replacement of the Laser Pickup, pay attention to the following handling instructions since the laser diode in the Laser Pickup is not resistant to static electricity.

(1)Grounding

When you repair a Laser Pickup, first ground the human body, as well as the measuring instruments and other tools (with particular caution to soldering iron). What'smore, your workbench and floor

should desirably be grounded using conductive sheet or copper plate. See Fig. 1.1.

NOTE: Be careful so as not to let your
clothes touch the Laser Pick~p. as
static electricity on the clothes will	.
not be released even if your body is	·
grounded.

HUOMAUTUS

Jos nuppeja, kytkimia ja saatimia ym, saiidetaan tai laitetta kaytetaan toisella tavalla kuin on selostettu, tuloksena saattaa olla vaarallista lasersateiden vuotoa. CD-soittimen saat6 ja korjaus on jatettava aina asiantuntevan huoltoteknikon tehtavaksi.

	(2) Discharge of Electricity	~
	Be sure to discharge electricity from objects
	brought into contact with the Laser Pickup (i.e.,
	soldering iron, tweezers, probes, volt-ohm-meter	Loser Pickup
	probes, etc.) before starting work by contacting
	them with the body chassis. Besides, never touch	IMn
	the Laser Pickup while power is applied.

(4)Remove the screws F05 (M2x3 + Pan (Black Chromate), 5 pcs), disengage F06 (Cut Washer 1.2x3x 0.125), and detach F07 (Loading Guide Ass'y)by lifting it upward.

To separate F07 (Loading Guide Ass'y)from the Loading Chassis Ass'y,it is required to unsolder the flexible cable from the Loading Motor Ass'y.

2.12.3. Installing the Loading Guide Ass'y

When installing the Loading Guide Ass'yin the Loading Chassis Ass'y,follow the steps below:

Note that the 3 places "A"-"B", "C"-"D" and "E"-"F" (see Figs. 2.12.1 and 2.12.2) must be correctly positioned.

(1)First, temporarily mount the Plate LG R of the Loading Guide Ass'yon the Loading Chassis Ass'ywith two screws "G", as it can move freely and come in contact with other parts. Refer to Fig. 2.12.2.

(2)Turn the movable Plate PLS Sub Ass'y"H" to bring it to the position shown in Fig. 2.12.2.

(3)Insert the shaft "A" of the Loading Guide Ass'yinto the hole "B" of the gear train on the Loading Chassis Ass'y.(After insertion, the Loading Guide Ass'ywill float from the Loading Chassis Ass'ya little.)

Loading Guide Ass'y

(4)While opening the Loading Guide L outward, align the hole "C" of the Plate PLS Sub Ass'ywith the pin "D" of the Loading Guide Ass'yand, at the same time, align the pin "E" of the Plate PLS Sub Ass'ywith the hole "F" of the Loading Guide Ass'y.Then, engage them each other.

(5)Move the part "I" in the direction shown by the arrow. Then, be sure that the Loading Guide Ass'yis securely seated to the Loading Chassis Ass'y.

(6)Fasten the cut washer F06 and 5 screws F05 to mount the Loading Guide Ass'y.

3.1. Gear Position Adjustments around the Stocker Drive Gear

Refer to Fig. 3.1.

NOTE: To turn the large Stocker Drive Gear, depress the part "A" with your finger tip as shown in Fig. 3.1.

3.1.1.Positioning the STCD Gear and Disc Lock SG The STCD Gear and two Disc Lock SGs must be positioned as shown in Fig. 3.1.

3.1.2.Positioning the Stocker Screw Gears

The four Stocker Screw Gears must be positioned as shown in Fig. 3.1.

(1)Aligning the two Stocker Screw Gear at the front: Align the mark (projection) on the gear of the Stocker

Screw Gear with the mark lholel on the lame Stocker

Drive Gear as shown in the figure.

NOTE: Since the mark (projection) on the gear is difficult to find, it is a good idea to reflect light to find it.

(2)Aligning the two Stocker Screw Gear~: Align the mark (projection) on the gear of the Stocker

Screw Gear with the mark lholel on the chassjs as shown in the figure.

For details, refer to 2.10.2 "Installing the Stocker Ass'yand Disc Holders".

3.2. Disc Lock Drive Gear Positioning

(1)Lower the Disc Lock Sleeve until it reaches the lowest position. Namely, turn the Disc Lock Drive Gear fully clockwise until it stops.

(2)Install the Disc Lock Plate so that its 3rd tooth engages with the Disc Lock Drive Gear as shown in Fig. 3.2.

3.3. Loading Guide R B Positioning

Install the Loading Guide R B so that its gear is engaged with the P Arm Gear as shown in Fig. 3.3.

In this case, be sure that the Loading Guide R B is fully pushed against the Loading Plate R Sub Ass'y.
