1. Precautions
1-1 Safety Precautions
1) Before returning an instrument to the customer,
always make a safety check of the entire instrument,
including, but not limited to, the following items:
(1) Be sure that no built-in protective devices are
defective or have been defeated during servicing.
(1)Protective shields are provided to protect both
the technician and the customer. Correctly replace
all missing protective shields, including any
removed for servicing convenience.
(2)When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place
all protective devices, including, but not limited to,
nonmetallic control knobs, insulating fish papers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not operate
this instrument or permit it to be operated without
all protective devices correctly installed and
functioning.
(2) Be sure that there are no cabinet openings through
which adults or children might be able to insert
their fingers and contact a hazardous voltage. Such
openings include, but are not limited to, excessively
wide cabinet ventilation slots, and an improperly
fitted and/or incorrectly secured cabinet back
cover.
(3) Leakage Current Hot Check-With the instrument
completely reassembled, plug the AC line cord
directly into a 230V(220V ~ 240V) AC outlet. (Do
not use an isolation transformer during this test.)
Use a leakage current tester or a metering system
that complies with American National Standardsp
institute (ANSI) C101.1 Leakage Current for
Appliances and Underwriters Laboratories (UL)
1270 (40.7). With the instrument’s AC switch first in
the ON position and then in the OFF position,
measure from a known earth ground
(metal water pipe,
conduit, etc.) to all exposed metal parts of the
instrument (antennas, handle brackets, metal
cabinets,
screwheads, metallic overlays, control shafts,
etc.), especially any exposed metal parts that offer
an electrical return path to the chassis.
Any current measured must not exceed 0.5mA.
Reverse the instrument power cord plug in the outlet
and repeat the test. See Fig. 1-1.
Any measurements not within the limits specified
herein indicate a potential shock hazard that must
be eliminated before returning the instrument to
the customer.
Fig. 1-1 AC Leakage Test
(4) Insulation Resistance Test Cold Check-(1) Unplug
the power supply cord and connect a jumper wire
between the two prongs of the plug. (2) Turn on the
power switch of the instrument. (3) Measure the
resistance with an ohmmeter between the
jumpered AC plug and all exposed metallic cabinet
parts on the instrument, such as screwheads,
antenna, control shafts, handle brackets, etc. When
an exposed metallic part has a return path to the
chassis, the reading should be between 1 and 5.2
megohm. When there is no return path to the chassis,
the reading must be infinite. If the reading is
not within the limits specified, there is the possibility
of a shock hazard, and the instrument must be
repaired and rechecked before it is returned to the
customer. See Fig. 1-2.

notes on or inside the cabinet, or on the chassis.
3) Design Alteration Warning-Do not alter or add to
the mechanical or electrical design of this
instrument.
Design alterations and additions, including
butnotlimitedto,circuitmodicationsandthe
addition of items such as auxiliary audio output
connections, might alter the safety characteristics of
this instrument and create a hazard to the user. Any
design alterations or additions will make you, the
servicer, responsible for personal injury or property
damage resulting therefrom.
4) Observe original lead dress. Take extra care to
assure correct lead dress in the following areas:
(1) near sharp edges, (2) near thermally hot parts (be
sure that leads and components do not touch
thermally
hot parts), (3) the AC supply, (4) high voltage,
and (5) antenna wiring. Always inspect in all areas
for pinched, out-of-place, or frayed wiring, Do not
change spacing between a component and the
printed-circuit board. Check the AC power cord for
damage.
5) Components, parts, and/or wiring that appear to
have overheated or that are otherwise damaged
should be replaced with components, parts and/ or
wiringthatmeetoriginalspecications.
Additionally, determine the cause of overheating
and/or damage and, if necessary, take corrective
action to remove any potential safety hazard.
6) Product Safety Notice-Some electrical and mechanical
parts have special safety-related characteristics
which are often not evident from visual inspection,
nor can the protection they give necessarily be
obtained by replacing them with components rated
for higher voltage, wattage, etc. Parts that have
specialsafetycharacteristicsareidentiedby
shading,
an ( )or a ( )on schematics and parts lists. Use
of a substitute replacement that does not have the
same safety characteristics as the recommended
replacementpartmightcreateshock,reand/or
other hazards. Product safety is under review
continuously and new instructions are issued
whenever appropriate.

1-3 ESD Precautions
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be damagedeasily by static electricity.
Such components commonly are called Electrostatically Sensitive Devices(ESD). Examples of typical ESD
devicesareintegratedcircuitsandsomeeld-effect
transistors and semiconductor chip components. The
following techniques should be used to help reduce
the incidence of component damage caused by static
electricity.
(1) Immediately before handling any semiconductor
component or semiconductor-equipped assembly,
drain off any electrostatic charge on your body by
touching a known earth ground. Alternatively,
obtain and wear a commercially available
discharging wrist strap device, which should be
removed for potential shock reasons prior to
applying power to the unit under test.
CAUTION : Be sure no power is applied to the chassis
or circuit, and observe all other safety precautions.
(8) Minimize bodily motions when handling
unpackaged replacement ESD devices.
(Otherwise harmless
motion such as the brushing together of your
clothes fabric or the lifting of your foot from a
carpetedoorcangeneratestaticelectricity
sufcienttodamageanESDdevice).
(2) After removing an electrical assembly equipped
with ESD devices, place the assembly on a
conductive surface such as aluminum foil, to
prevent electrostatic
charge buildup or exposure of the assembly.
(3) Use only a grounded-tip soldering iron to solder or
unsolder ESD devices.
(4) Use only an anti-static solder removal devices.
Somesolderremovaldevicesnotclassiedas
“anti-static”cangenerateelectricalchargessufcient
to damage ESD devices.
(5) Do not use freon-propelled chemicals. These can
generateelectricalchargessufcienttodamage
ESD devices.
(6) Do not remove a replacement ESD device from its
protective package until immediately before your
are ready to install it.(Most replacement ESD
devices are packaged with leads electrically shorted
together by conductive foam, aluminum foil or
comparable conductive materials).
(7) Immediately before removing the protective
materials from the leads of a replacement ESD
device, touch the protective material to the
chassis or circuit assembly into which the device
will be installed.
1-4 Handling the optical pick-up
The laser diode in the optical pick up may suffer electrostatic breakdown because of potential static electricity from clothing and your body.
The following method is recommended.
(1) Place a conductive sheet on the work bench (The
black sheet used for wrapping repair parts.)
(2) Place the set on the conductive sheet so that the
chassis is grounded to the sheet.
Precautions
Fig.1-3
(3) Place your hands on the conductive sheet(This
gives them the same ground as the sheet.)
(4) Remove the optical pick up block
(5) Perform work on top of the conductive sheet. Be
careful not to let your clothes or any other static
sources to touch the unit.
Be sure to put on a wrist strap grounded to the sheet.
Be sure to lay a conductive sheet made of copper
etc. Which is grounded to the table.
(6) Short the short terminal on the PCB, which is inside
the Pick-Up ASS’Y, before replacing the Pick Up. (The short terminal is shorted when the Pick Up Ass’y is being lifted or moved.)
(7) After replacing the Pick-up, open the short terminal
on the PCB.

When switching from the rst layer to the second layer of a dual-layered DVD Video disc, there may be momentary distortion in the image and sound. This is not a malfunction of the unit.
Once a DVD-RW/ recorded in Video Mode is nalised, it becomes DVD-Video.
An audio disc on which 44.1 kHz PCM Audio is recorded.
Plays CD-DA format audio CD-R and CD-RW discs.
The unit may not be able to play some CD-R or CD-RW discs due to the condition of the recording.
Use a 700MB (80 minutes) CD-R/-RW disc. If possible, do not use a 800MB (90 minutes) or above disc, as the disc may not
play back.
If the CD-R/-RW disc was not recorded as a closed session, you may experience a delay in the early playback time, all
recorded les may not play.
Some CD-R/-RW discs may not be playable with this unit, depending on the device which was used to burn them. For contents recorded on CD-R/-RW media from CDs for your personal use, playability may vary depending on contents and discs.
Once a DVD recorded in Video Mode is nalised, it becomes DVD-Video.
You can record onto the available space on the disc and perform editing functions such as giving titles to discs and pro-
grammes and erasing programmes before nalising.
When programming is erased from a DVD , that space does not become available. Once an area on a DVD is recorded on, that area is no longer available for recording, whether the recording is erased or not.
It takes about 30 seconds for the unit to complete recording management information after recording nishes.
This product optimizes the DVD for each recording. Optimizing is carried out when you start recording after inserting the
disc or turning on the unit. Recording onto the disc may become impossible if optimizing is carried out too many times.
Playback may be impossible in some cases due to the condition of recording.
This unit can play back DVD discs recorded and nalised with a Samsung DVD video recorder. It may not be able to
play some DVD discs depending on the disc and the condition of the recording.
Recording and playback can be performed on DVD-RW discs in both the Video and VR Modes.
Once a DVD-RW recorded in both the Video and VR Modes is nalised, you cannot perform additional recording.
Once a DVD-RW recorded in Video Mode is nalised, it becomes DVD-Video.
In both modes, playback can be performed before and after nalisation, but additional recording, deleting and editing can
not be performed after nalisation.
If you want to record the disc in VR Mode and then record in V Mode, be sure to execute Format. Be careful when executing
Format because all the recorded data may be lost.
A DVD-RW blank disc is initialised to VR Mode when rst initialised.
With DVD+RW discs, there is no difference between DVD-Video format(Video mode) and DVD-Video Recording format(VR
mode).
Finalising is generally unnecessary when using a DVD+RW disc.
Ensure that the recording mode is set to VR mode. Otherwise, this product will not be able to play the recording.
You cannot play a DVD-RAM in most DVD components due to compatibility issues.
Only DVD-RAM standard Version 2.0. discs can be played in this unit.
