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

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.

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
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.

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.

2. Laser Diode (LD)

6. Deterioration

(1) Protect your eyes
The laser beam may damage the human eye, since the
intensity of the focused spot may reach 7×10 3
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.

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)).

(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. As2O 3,
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 shortcircuited 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.

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.

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.

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.

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.

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.

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.
