SAFETY PRECAUTIONS

The following check should be performed for the continued prtection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before reterning the unit to the customer,make sure you make either (1) aleakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 miliamps, or if hte resistance from chassis to either side of the power cord is less than 460 kohms, the unit is detective.

CD TEST MODE

Setting of the test mode

How to start the test mode: Turn on the power in the condition that CLOSE (Pin No. 3 )

and OPEN (Pin No. 4 ) of CX053 are being shorted. ( “01” is indicated on the DISPLAY)

To exit from the test mode, turn off the power. (Refer to Fig. 1 “Test Point Layout”)

Fig. 1 “Test Point” Layout

* Laser light of the pickup is always emitted regardless of DISC loading in the test mode.

You may lose your eyesight if you look into the laser directly.

So be careful enough when operating in the test mode.

Used DISC: A-BEX TCD784

Explanation of each button

* Use only the buttons described below for operations while in the test mode,

and don’t push any other buttons.

Names of buttons Operation

OPEN / CLOSE * Loads or unloads DISC

PLAY * Emits laser light * Repeats search operation (No DISC condition: While it’s pressed) * Actuates focus servo (In case of DISC loaded) * Actuates tracking servo

STOP * Stops operation

PAUSE * Performs auto adjustment

MANUAL SEARCHFORWARD / REVERSE

* Moves pickup

How to check the test mode

( 1 ) DISC discrimination, adjustment

* Insert DISC, and press the PAUSE button.

* “06 Adj” is displayed, and discrimination of DISC size 8 cm/12 cm, discrimination of

DISC reflectance (CD, CD-R/CD-RW), adjustment of focus, tracking offset,

and EF balance will be performed. (Adjusted values are not displayed: Refer to Fig. 2, 3)

Fig. 2 DISC discrimination, adjustment Fig. 3

(Case of CD-RW) Adjustment of EF balance

* After completing the discrimination and adjustment, it becomes stop condition.

* Once discrimination of DISC has been carried out in the “06 Adj” mode, discrimination of

size and reflectance is no longer made, and only adjustment will be performed.

( 2 ) Checking of servo state

* Press the PLAY button after performing above (1) “DISC discrimination, adjustment”.

* “02 L on” is displayed, and the laser will start to light. (The pickup may vibrate with a rattling

noise if DISC has been loaded, but this is not abnormal.)

* Press the PLAY button again.

* “03 F on”is displayed. DISC starts turning,and focus servo will be actuated. (Refer to Fig. 4, 5)

* Monitor HF signal using the test terminals, HF of CX053 (Pin No. 1 ) and

VC of CX063 (Pin No. 5 : 2.5V ref. signal). Check that the signal’s amplitude

is 1.5V 0.3Vp-p. (Refer to Fig. 6)

Caution for Handling the Laser Pick-up

The laser pick-up KSS-213C is assembled and preciselyadjusted using a sophisticated manufacturing process in ourplant. Do not disassemble or attempt to readjust it. Pleaseobserve the following instructions carefully in handling thepick-up.

1. Handle with Care

(1) StorageDo not store the pick-up in dusty, high-temperatured orhigh-humidity environments.

(2) Please take care for preventing from shock by fallingdown or careless handling.

2. Laser Diode (LD)

(1) Protect your eyesThe laser beam may damage the human eye, since theintensity of the focused spot may reach 7×103

W/cm2 even if the intensity at the objective lens is 400µWmaximum. As the light beam spreads after focusedthrough the objective lens, it does not effect you in theplace as far as more than 30 cms. However, do not lookat the laser light beam either through the objective lensdirectly nor another lens or a mirror.

(2) Poison of AsSince the LD chip contains As (Arsenic), as GaAs +GaAlAs, as known as the poison, although the poison isrelatively weak, in comparing with others, e.g. As2O3,AsCl3 etc., and the amount is small, avoid putting thechip in acid or an alkali solution, heating it over 200 °Cor putting it into your mouth.

(3) Avoid surge current or electrostatic dischargeThe LD may be damaged or deteriorated by its ownstrong light if a large current is supplied to it, even if onlya short pulse.Make sure that there is no surge current in the LD drivingcircuit by switches or else. Be careful to handle pick-upas it may be damaged in a moment by humanelectrostatic discharge. The pins of the LD are short-circuited by solder for protection during shipment.For safety handling of an LD, grounding the human body,measuring equipments and jig is strongly recommended.And still it is further desirable to make use of mat on theplatform and floor for handling the LD.To open the short-circuit, remove the soldering quicklywith a soldering iron whose metal part is grounded.The temperature of the soldering iron should be less than320°C (30W).

3. Actuator

(1) The performance of the actuator may be affected ifmagnetic material is located nearby, since the actuatorhas a strong magnetic circuit. Do not permit dust to enterthrough the clearance of the cover.

(2) Cleaning the lensIt may change the specifications by attaching dust orash on the objective lens. Clean the lens with a cleaningpaper dampened with, not pressing lens with so muchstrength by the cleaning paper.

4. Metal Bearing

As the metal bearing of Cu-compound sintered alloy isimpregnated with FROIL946P, never fail to supply thebushing with the same lubricant at the time of replacing thepick-up.

5. Handling

Please handle the laser pick-up with holding the slide base.(resin molded part).When either a part of human body or some other things mayhappen to touch directly with the circuit part of P.W.Board, itmay cause deterioration, take careful attention in handlingthis base.

6. Deterioration

As KSS-213C comprises built-in RF Amp and APC circuit,resists stronger against external electrostatic damages thanthe former typed pickup. However, there is possibility ofpickup deterioration in the following cases.(1) Low HF level, or with great numbers of jitters.(2) Tracking offset (EF Balance) is out of order (Refer to

“Confirmation Method of Adjustment”for confirmation (1)and (2)).
