THE COMPACT DISC _
1. Precautions on handling compact discs
•Do not allow fingerprints, oil or dust on the surface of the
compact disc. If the signal surface is dirty, wipe it off with asoft,
dry cloth. Wipe in circular motions from the center to the outside
edge.
Use
of DENON's AMC-20/21 CD cleaner is recommended.
•Do not use water, benzene, thinner, record sprays, electrostatic
proof chemicals, or silicone-treated cloth to clean discs.
•
When handling discs always take care to prevent damaging the
surface, in particular when removing a disc from the case and
returning it.
•Do
not bend compact discs.
•Do
not apply heat to compact discs.
•Do
not enlarge the hole in the center of the disc.
•Do
not write on the disc and do not attach any labels.
•
Condensation will form on the disc surface if it is brought into a
warm room from a cold area, such as outdoors during winter.
Wait until the condensation disappears. Never dry discs with
hair dryers, etc.
2. Precautions on storage
• After playing adisc, always return it to its case.
•Keep
discs in the cases when they are not to be played. This will
protect them from dust and dirt and prolong their service life.
•
Do not store discs in the following places:
1) Places exposed to direct sunlight for a considerable time.
2) Places subject to accumulation of dust or high humidity.
3) Places exposed to high temperatures, such as close to
heater outlets.
The CD player uses a microcomputer for controlling internal electronic
circuits. In
the event that the player is used while a near-by tuner or TV is
turned on, although unlikely, interference could occur either in the sound
from the tuner or the picture of the TV. To avoid this, please take the
following precautions.
•Keep
the CD player as far away from the tuner or TV set as possible.
•Keep
the power cable and connecting cable of the CD player separate
from the antenna wires of the tuner and TV.
•Interference is
particular likely to occur when an indoor antenna or a
300-ohm feeder cable is used. Thus, use of an outdoor antenna and
75-ohm coaxial cable is strongly recommended.

Cautions for Handling the Laser Pick-up
The laser pick-up KSS-151A is assembled and precisely
adjusted using asophisticated
manufacturing process in our
plant. Do not disassemble or attempt to readjust it. Please
keep the following instructions carefully in handling 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 7x 10
3
WI
cm2even if the intensity at the objective lens is
400 J.1W maximum. As tl}e 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 +
GaAIAs, as known as the poison, although the poison
is relatively weak, in comparing with others, e.g.
AS
2°3,AsCI3etc., 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 it's own
strong light if alarge 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 recom-
mended. 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 asoldering 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 effected 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 object lens. Clean the lens with acleaning
paper dampened a
little water, 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 FROI L946P (*Part No. 529 0054007),
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
(rosin 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
When difficulty occurs either in focus or tracking adjust-
ment nor able to adjust the focus or tracking, it seems that
the laser pick-up is deteriorated. In these cases, check a
value
of laser diode current and give adecision for
deterioration.
7. Fundamental Deterioration Decision of Laser Pick-up
(1)
If avoltage value in between No.2 and NO.6 pins of
TP102 of the servo and signal processor unit, the value
of laser diode current "iop" can be found by a formula
". 1"- V1
lOP - 22 .
(2)
If an "iop" exceeds ±10% compared with the lOP
indication on the laser pick-up nameplate, there is a
fair chance for deterioration when it is checked under
a
circumambient temperature 23°C.
(3) When the circumambient temperature changes ±lO°C,
"iop1" will change ±5%. The "iop1" will also be
changed by the passage of time.
(4) In case of the above conditions taking into considera-
tion and performed the adjustment in proper way, if
the HF level at pin No. CD of TP102 on Main Unit,
and in between GND4 becomes 1V or lesser values; or
ajitter occurs great, the laser pick-up may be deterio-
rated.
