1 SAFETY PRECAUTIONS
1.1. GENERAL GUIDELINES
1. Be careful during removing metal parts, sharp edges.
2. When servicing, observe the original lead dress. If a short
circuit is found, replace all parts which have been
overheated or damaged by the short circuit.
3. After servicing, see to it that all the protective devices such
as insulation barriers, insulation papers shields are properly
installed.
4. After servicing, make the following leakage current checks
to prevent the customer from being exposed to shock
hazards.
1.1.1. LEAKAGE CURRENT COLD
CHECK
1. Unplug the AC cord and connect a jumper between the two
prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between
the jumpered AC plug and each exposed metallic cabinet
part on the equipment such as screw heads, connectors,
control shafts, etc. When the exposed metallic part has a
return path to the chassis, the reading should be between
1MΩ and 5.2MΩ.
When the exposed metal does not have a return path to
the chassis, the reading must be infinity.
Figure 1
1.1.2. LEAKAGE CURRENT HOT CHECK
1. Plug the AC cord directly into the AC outlet. Do not use an
isolation transformer for this check.
2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF
capacitors, between each exposed metallic part on the set
and a good earth ground such as a water pipe, as shown in
Figure 1.
3. Use an AC voltmeter, with 1000 ohms/volt or more
sensitivity, to measure the potential across the resistor.
4. Check each exposed metallic part, and measure the
voltage at each point.
5. Reverse the AC plug in theAC outlet and repeat each ofthe
above measurements.
6. The potential at any point should not exceed 0.75 volts
RMS. A leakage current tester (Simpson Model 229 or
equivalent) may be used to make the hot checks, leakage
current must not exceed 1/2 milliampere. In case a
measurement is outside of the limits specified, there is a
possibility of a shock hazard, and the equipment should be
repaired and rechecked before it is returned to the
customer.

2 WARNING
2.1. PREVENTION OF ELECTROSTATIC DISCHARGE (ESD) TO
ELECTROSTATIC SENSITIVE (ES) DEVICES
DMR-EX95VEG / DMR-EX95VEB
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatic Sensitive (ES) Devices. Examples of typical
ES devices are integrated circuits and some field-effect
transistor-sandsemiconductor"chip"components.The
following techniques should be used to help reduce the
incidence of component damage caused by electrostatic
discharge (ESD).
1. Immediatelybeforehandlinganysemiconductor
component or semiconductor-equipped assembly, drain off
any ESD on your body by touching a known earth ground.
Alternatively, obtain and wear a commercially available
discharging ESD wrist strap, which should be removed for
potential shock reasons prior to applying power to the unit
under test.
2. After removing an electrical assembly equipped with ES
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 ES devices.
4. Use only an anti-static solder removal device.
Some solder removal devices not classified
as "anti-static (ESD protected)" can generate electrical
charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it.
(Most replacement ES devices are packaged with leads
electrically shorted together by conductive foam, aluminum
foil or comparable conductive material).
7. Immediately before removing the protective material from
the leads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into which the
device will be installed.
Caution
Be sure no power is applied to the chassis or circuit, and
observe all other safety precautions.
8. Minimizebodilymotionswhenhandlingunpacked
replacement ES devices. (Otherwise harmless motion such
as the brushing together of your clothes fabric or the lifting
of your foot from a carpeted floor can generate static
electricity sufficient to damage an ES device).

2.3. SERVICE CAUTION BASED ON LEGAL RESTRICTIONS
General description about lead free Solder (PbF)
•
• The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used
• •
for this equipment in considering the globally environmental conservation.
•
• The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists
• •
of tin (Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx. 30 degrees C (86°F)
more than that of the normal solder.
Service caution for repair work using Lead Free Solder (PbF)
•
• The lead free solder has to be used when repairing the equipment for which the lead free solder is used.
• •
•
• To put lead free solder, it should be well molten and mixed with the original lead free solder.
• •
•
• Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC.
• •
•
• Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt
• •
the lead free solder.
•
• Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature
• •
at 350±30 degrees C (662±86°F). When soldering or unsoldering, please completely remove all of the solder
on the pins or solder area and be sure to heat the soldering points with the Pb free solder until it melts enough.
Definition of PCB Lead Free Solder being used
•
• The letter of “Pbf is printed either foil side or component side using the lead free solder.
• •
Recommended Lead Free Solder (Service Parts Route.)
•
• The following 3 types of lead free solder are available through the service parts route.
• Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%

in treating file to which DRM is applied.
1. Registration Code display function
2. User’s registration and approval function
3. Rental management function
5.1.3.1. REGISTRATION CODE DISPLAY FUNCTION
Registration Code is alphanumeric character sequence 8 bytes inputted as recorder information, in case a use purchases or rent
a DivX DRM file in a network. Registration code is a character sequence generated at random, and differs in each recorder.
Moreover, Registration code is updated by new user authentication ever if same recorder.
5.1.3.2. USER’S REGISTRATION AND APPROVAL FUNCTION
•
• Only one user can register for one recorder. If user’s
• •
registration is not done with the recorder, DivX file cannot
be played back.
•
• User’s registration is performed only when a DivX DRM
• •
file is first chosen by recorder
•
• DivX DRM file that can perform user’s registration is only a file that is registered Registration Code and purchased or rented.
• •
•
• User authentication is performed whenever DivX DRM file is played back. Error message is displayed when failing in user’s
• •
registration and approval.
5.1.3.3. RENTAL MANAGEMENT FUNCTION
There are purchase file without registration of number of playback and rental files with registration of number of playback as Divx
file. Number of playback of rental file is counted by the recorder. When rental file is played, remaining number of times that can be
played back will be shown to users, recorder requests users to input yes or no. Following specifications have been installed for the
rental files in the purpose to clarify the count condition of number of times of playback.
•
• Conditions on counting number of times of play.
• •
1. When a file was opened successfully. (At the time of playback start)
2. When you have done review operation from the start. (Skip to file head)
−
− At this time, remaining number of times that can be played back and confirmation message
− −
[Do you play really?] are displayed.
−
− When the playback point has been skipped to the top of title, number of playback is not counted if the top of title was
− −
not recognized.
−
− Even if the power failure occurs after start of playback of rental file, number of times of playback counted at start of the
− −
playback is held as it is.
(Though playback stops by power failure,
the number of times of playback is not counted.)
When it has reached head of title, the playback is ended, and screen becomes DivX menu (There is no resume) and then cursor
is located on title that has been played back.Then if the same file was continuously played back, it begins to playback from the
file head.
Note:
Above mentioned stored user information and number of times of playback are not erased by update of firmware or by
initialization by test mode.

8.2.3. (VHS) SELF-DIAGNOSIS FUNCTIONS
This model has a self-diagnosis. If the VHS section detects trouble during installation or during use, the power is automatically
turned off or become power-save mode and it is memorized into the EEPROM (IC9705) as error code of two-digit number. It’s
memorized error code can be displayed in "second" display portion (the last 2 digits of the FIP) by placing the unit is Service Mode
Number 2 when turning on the Service Information Display as for example "01" or "02" etc. as below. If a second error occurs, the
most recent error will be memorized and can be displayed in Service Mode Number 2. It can be memorized until 3 self-diagnosis
histories in maximum.
In order to erase the memorized error code, press STOP and EJECT buttons on the Front Panel simultaneously over 5 seconds
during turning on Service Information Display mode.

Please will always pass the customer “Warning for Customers Who Use the DivX Video-on-Demand content.” with the product
and get it when you unavoidably exchange EEPROM or P.C.B. including EEPROM (When the product is exchanged,
it is the same.).
You must use print attached to service part (EEPROM or P.C.B. including EEPROM) or must use copy of print below as
“Warning for Customers who use the DivX Video-on-Demand content.”Information needed without fail for the customer for
whom it is used continuing DivX Video-on-Demand Service
to “Manual for the customer” is recorded.
Appendix:* Parts that memorize user’s information are only EEPROM.* The registration of Registration Code is possible for half
a year up to 6 recorders up to 10 recorders a year.
Replacement of EEPROM or P.C.B. including EEPROM spends one of this.
Registration Code is memorized in EEPROM (RFKxxxxxx).
Model without VHS: on Main P.C.B.Model with VHS: on Digital I/F P.C.B. (Power & DVD I/F/P.C.B.)If exchange above P.C.B.
or EEPROM, new registration Code differ from previous Registration Code will be generated.In this case if your customer uses
DivX Video-on-Demand service, he/she will no longer be able to play any content
that he/she purchased under that same registration code.Therefore your customer will need to obtain and register the new

16 APPENDIX FOR SCHEMATIC DIAGRAM
16.1. VOLTAGE AND WAVEFORM CHART
NOTE:
•
• Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance)
• •
with the chassis taken as standard.
Therefore, there may exist some errors in the voltage values, depending on the internal impedance of the DC circuit tester.
