SECTION 1
PRECAUTION
1.1 Safety Precautions
(1) This design of this product contains special hardware and
many circuits and components specially for safety purpos-
es. For continued protection, no changes should be made
to the original design unless authorized in writing by the
manufacturer. Replacement parts must be identical to
those used in the original circuits. Services should be per-
formed by qualified personnel only.
(2) Alterations of the design or circuitry of the product should
not be made. Any design alterations of the product should
not be made. Any design alterations or additions will void
the manufacturers warranty and will further relieve the
manufacture of responsibility for personal injury or property
damage resulting therefrom.
(3) Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteris-
tics are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by us-
ing replacement components rated for higher voltage, watt-
age, etc. Replacement parts which have these special
safety characteristics are identified in the Parts List of Ser-
vice Manual. Electrical components having such features
are identified by shading on the schematics and by ( ) on
the Parts List in the Service Manual. The use of a substitute
replacement which does not have the same safety charac-
teristics as the recommended replacement parts shown in
the Parts List of Service Manual may create shock, fire, or
other hazards.
(4) The leads in the products are routed and dressed with ties,
clamps, tubings, barriers and the like to be separated from
live parts, high temperature parts, moving parts and/or
sharp edges for the prevention of electric shock and fire
hazard. When service is required, the original lead routing
and dress should be observed, and it should be confirmed
that they have been returned to normal, after reassem-
bling.
(5) Leakage shock hazard testing
After reassembling the product, always perform an isola-
tion check on the exposed metal parts of the product (an-
tenna terminals, knobs, metal cabinet, screw heads,
headphone jack, control shafts, etc.) to be sure the product
is safe to operate without danger of electrical shock.Do not
use a line isolation transformer during this check.
• Plug the AC line cord directly into the AC outlet. Using a
"Leakage Current Tester", measure the leakage current
from each exposed metal parts of the cabinet, particular-
ly any exposed metal part having a return path to the
chassis, to a known good earth ground. Any leakage cur-
rent must not exceed 0.5mA AC (r.m.s.).
• Alternate check method
Plug the AC line cord directly into the AC outlet. Use an
AC voltmeter having, 1,000Ωper volt or more sensitivity
in the following manner. Connect a 1,500Ω10W resistor
paralleled by a 0.15µF AC-type capacitor between an ex-
posed metal part and a known good earth ground.
Measure the AC voltage across the resistor with the AC
voltmeter.
Move the resistor connection to each exposed metal
part, particularly any exposed metal part having a return
path to the chassis, and measure the AC voltage across
the resistor. Now, reverse the plug in the AC outlet and
repeat each measurement. Voltage measured any must
not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5
mA AC (r.m.s.).
1.2 Warning
(1) This equipment has been designed and manufactured to
meet international safety standards.
(2) It is the legal responsibility of the repairer to ensure that
these safety standards are maintained.
(3) Repairs must be made in accordance with the relevant
safety standards.
(4) It is essential that safety critical components are replaced
by approved parts.
(5) If mains voltage selector is provided, check setting for local
voltage.
1.3 Caution
Burrs formed during molding may be left over on some parts
of the chassis.
Therefore, pay attention to such burrs in the case of pre-
forming repair of this system.
1.4 Critical parts for safety
In regard with component parts appearing on the silk-screen
printed side (parts side) of the PWB diagrams, the parts that are
printed over with black such as the resistor ( ), diode ( )
and ICP ( ) or identified by the " " mark nearby are critical
for safety. When replacing them, be sure to use the parts of the
same type and rating as specified by the manufacturer.

1.6 Hard Disk Drive (HDD) Handling Precautions
The HDD is a precision device for use in reading and writing a large amount of data on or from a disk rotating at a high speed. If it is
not handled carefully, either abnormal operation may result or it may not be possible to read data. The HDD is sensitive to the following
items and special care is required in safeguarding against them when handling an HDD. Also take care in handling a set incorporating
an HDD.
(1) Vibrations and impacts
(2) Static electricity
(3) Rough handling
1.6.1 Handling in transport, etc.
• Be sure to place the HDD in the manufacturer's specified pack-
age carton before transport.
• When receiving a package containing an HDD, check that the
package carton is not damaged (such as having holes in the
carton, crushed corners, etc.).
• Do not impact the packaging carton when loading or unloading
it.
• It is not permitted to use the inner package carton only for
transporting an HDD.
• Do not stack package cartons one upon another.
1.6.2 Handling an HDD in the stand-alone status
• When handling an HDD on a hard workbench, place an anti-
static mat (rubber sheet) or similar object on the hard surface
(to prevent any impacts occurring between the HDD and
bench).
• Do not stack the HDDs one upon another.
• Do not knock an HDD with a hard object (such as a screwdriv-
er).
• Do not place an HDD on its side panel without using a support
(do not place an HDD in an unstable position).
1.6.3 Handling the installation of an HDD
• Place antistatic mats or similar sheets on all of the surfaces on which work is conducted or when the HDD is transported.
• Do not permit the HDD to knock against the set's brackets.
• When screwing the brackets, be careful not to knock the HDD. When using a power screwdriver, use a low-shock model and arrange
the tightening torque properly.
• When mounting an HDD in a main body, take care not to apply excessive force to the brackets.

5.4 Updating the firmware of the drive unit
• Firmware update disc supports only DVD-RAM media.
• When firmware update is necessary, written discs are distributed by DIGITAL VIDEO STORAGE CATEGORY, CS group.
(1) Turn the main body ON, and switch the main body to “DVD”.
(2) Load the update DVD-RAM disc on the tray and close the tray.
(3) “READING” is displayed in the FL indicator and the update is started.
(4) In a short while “READING” in the FL indicator disappears, open the tray to remove the disc and close the tray.
(5) Turn the power OFF and pull out the power code from the wall socket, then plug the power cord into the wall socket again.
(6) Set to the JIG mode and check the firmware version of the drive.
5.5 Taking out a disc
<Method 1 >
There is a forced tray eject mode with electrical operation.
(1) Right after plugging in the power code (while “PLEASE” and “WAIT” blink alternately and it is displayed), keep pressing the
OPEN/CLOSE button of the main body.
(2) Remove the disc as the tray is ejected in a short while.
(3) The tray closes automatically at about five seconds.
<Method 2 >
When the disc cannot be removed by operating above <Method 1 >, open the front door of the main body manually and directly
press the EJECT button located in the lower right of the drive unit.
<Method 3 >
When neither <Method 1> nor <Method 2> can remove the disc, the tray can be ejected mechanically without turning the power on.
(1) Open the front door of the main body manually.
(2) Insert a fine wire (e.g. a straightened paper clip) into the hole in the lower part of the tray of the drive unit.
(3) As the tray ejects a little, pull out the tray manually.
5.6 Exchanging the fitting
As the fitting that comes with the service drive unit cannot be used, make sure to attach a service fitting when the drive unit is ex-
changed. The fitting that is removed from the old drive unit can be attached to the new drive unit.
The fitting can be removed by pulling upwards while opening out the lower part of the fitting outwards.

5.7 Initialization to the factory shipment state
When the initialization is operated, internal information changes as follows. It is essential to obtain the client’s permission before the
operation.
• All DVD library is all deleted.
• All the DVD initial settings go back to the initial status.
(1) Set to the JIG mode.
(2) Transmit “43-6F” with the JIG remote control unit.
(3) FL indicator displays “FACTORY”, and changes to “CHECK OK” after blinking for a short while.
(4) Pull out the power code from the wall socket.
(5) The JIG mode is forced to cancel at the same time with the initialization, check whether the JIG mode is canceled by plugging
the power code into the wall socket again. (The colon “:” in time display should be continuously ON, not blinking.)
If the JIG mode is not canceled, transmit “43-9D” with JIG remote control unit to cancel the JIG mode.
5.8 Setting after the drive unit replacement
When the drive unit is replaced, it is necessary to set a region code. Service drive units for replacement are not set for any region
code, and they are in an indefinite condition.
Make sure to set region code after attaching the drive unit to the main body.
Without the setting of the region code, discs that have regions cannot be played back.
5.8.1 Creating a region setting disc.
Please check the details of the region setting disc creation method by JS-NET.
(1) Download the region setting file from JS-NET.
(2) Write the region setting file into CD-R. Pay attention in the following points when writing the file into CD-R.
• Make sure to write in “Disc at Once”.
• Set the file compatibility to “ISO9660 format”. (ROMEO, JOLIET are disapproved).
If the writing method is not correct, the normal setting cannot be performed.
5.8.2 Setting the region
(1) Set for the JIG mode, and switch the main body to “DVD”.
(2) Load the region setting disc on the tray, and then close the tray.
(3) When the disc reading operation is completed, transmit “43-70” with the JIG remote control unit.
(4) FL indicator changes to “UPDATE”. Remove the disc as the tray will open for a few seconds.
(5) Then, check whether the FL indicator is “REGION 2”, and then close the tray.
(6) Turn the power OFF, and pull out the power code, and then plug the power code in again.
