CD TEST MODE

z 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.

z Used DISC: A-BEX TCD784

z 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 SEARCH

FORWARD / REVERSE

* Moves pickup

z 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)

Caution for Handling the Laser Pick-up

The laser pick-up KSS-213C is assembled and precisely

adjusted using a sophisticated manufacturing process in our

plant. Do not disassemble or attempt to readjust it. Please

observe the following instructions carefully in handling the

pick-up.

1. Handle with Care

(1) Storage

Do not store the pick-up in dusty, high-temperatured or

high-humidity environments.

(2) Please take care for preventing from shock by falling

down or careless handling.

2. Laser Diode (LD)

(1) Protect your eyes

The laser beam may damage the human eye, since the

intensity of the focused spot may reach 7×103

W/cm2 even if the intensity at the objective lens is 400µW

maximum. As the light beam spreads after focused

through the objective lens, it does not effect you in the

place as far as more than 30 cms. However, do not look

at the laser light beam either through the objective lens

directly nor another lens or a mirror.

(2) Poison of As

Since the LD chip contains As (Arsenic), as GaAs +

GaAlAs, as known as the poison, although the poison is

relatively weak, in comparing with others, e.g. As2O3,

AsCl3 etc., and the amount is small, avoid putting the

chip in acid or an alkali solution, heating it over 200 °C

or putting it into your mouth.

(3) Avoid surge current or electrostatic discharge

The LD may be damaged or deteriorated by its own

strong light if a large current is supplied to it, even if only

a short pulse.

Make sure that there is no surge current in the LD driving

circuit by switches or else. Be careful to handle pick-up

as it may be damaged in a moment by human

electrostatic 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 the

platform and floor for handling the LD.

To open the short-circuit, remove the soldering quickly

with a soldering iron whose metal part is grounded.

The temperature of the soldering iron should be less than

320°C (30W).

3. Actuator

(1) The performance of the actuator may be affected if

magnetic material is located nearby, since the actuator

has a strong magnetic circuit. Do not permit dust to enter

through the clearance of the cover.

(2) Cleaning the lens

It may change the specifications by attaching dust or

ash on the objective lens. Clean the lens with a cleaning

paper dampened with, not pressing lens with so much

strength by the cleaning paper.

4. Metal Bearing

As the metal bearing of Cu-compound sintered alloy is

impregnated with FROIL946P, never fail to supply the

bushing with the same lubricant at the time of replacing the

pick-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 may

happen to touch directly with the circuit part of P.W.Board, it

may cause deterioration, take careful attention in handling

this base.

6. Deterioration

As KSS-213C comprises built-in RF Amp and APC circuit,

resists stronger against external electrostatic damages than

the former typed pickup. However, there is possibility of

pickup 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)).

WARNING:

Parts marked with this symbol have critical characteristics.

Use ONLY replacement parts recommended by the manufacture.

CAUTION:

Before returning the unit to the customer, make sure you make either (1) a

leakage current check or (2) a line to chassis resistance check. If the leakage

current exceeds 0.5 milliamps, or if the resistance from chassis to either side

of the power card is less than 460 kohms, the unit is defective.

ALL RESISTANCE VALUES IN OHM. k=1,000 OHM M=1,000,000 OHM

ALL CAPACITANCE VALUES IN MICRO FARAD. P=MICRO-MICRO FARAD

EACH VOLTAGE AND CURRENT ARE MEASUERD AT NO SIGNAL INPUT

CONDITION.

CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR

NOTICE.

WARNING:

Parts marked with this symbol have critical characteristics.

Use ONLY replacement parts recommended by the manufacture.

CAUTION:

Before returning the unit to the customer, make sure you make either (1) a

leakage current check or (2) a line to chassis resistance check. If the leakage

current exceeds 0.5 milliamps, or if the resistance from chassis to either side

of the power card is less than 460 kohms, the unit is defective.

WARNING:

DO NOT return the unit to the customer until the problem is located and

corrected.

WARNING:

Parts marked with this symbol have critical characteristics.

Use ONLY replacement parts recommended by the manufacture.

CAUTION:

Before returning the unit to the customer, make sure you make either (1) a

leakage current check or (2) a line to chassis resistance check. If the leakage

current exceeds 0.5 milliamps, or if the resistance from chassis to either side

of the power card is less than 460 kohms, the unit is defective.

WARNING:

Parts marked with this symbol have critical characteristics.

Use ONLY replacement parts recommended by the manufacture.

CAUTION:

Before returning the unit to the customer, make sure you make either (1) a

leakage current check or (2) a line to chassis resistance check. If the leakage

current exceeds 0.5 milliamps, or if the resistance from chassis to either side

of the power card is less than 460 kohms, the unit is defective.

WARNING:

DO NOT return the unit to the customer until the problem is located and

corrected.

ALL RESISTANCE VALUES IN OHM. k=1,000 OHM M=1,000,000 OHM

ALL CAPACITANCE VALUES IN MICRO FARAD. P=MICRO-MICRO FARAD

EACH VOLTAGE AND CURRENT ARE MEASUERD AT NO SIGNAL INPUT

CONDITION.

CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR

NOTICE.

WARNING:

Parts marked with this symbol have critical characteristics.

Use ONLY replacement parts recommended by the manufacture.

CAUTION:

Before returning the unit to the customer, make sure you make either (1) a

leakage current check or (2) a line to chassis resistance check. If the leakage

current exceeds 0.5 milliamps, or if the resistance from chassis to either side

of the power card is less than 460 kohms, the unit is defective.

WARNING:

DO NOT return the unit to the customer until the problem is located and

corrected.
