1. Safety Precaution
1.1. General guidelines
1. When servicing, observe the original lead dress. Ifashort circuit
isfound, replace all parts which have been overheated or
damaged bythe short circuit.
2. After servicing, see to itthat all the protective devices such as
insulation barriers, insulation papers shields are properly
installed.
3. After servicing, make the following leakage current checks to
prevent the customer from being exposed to shock hazards.
1.1.1. Leakage current coldcheck
1. Unplug the AC cord and connect ajumper between the two
prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metalliccabinet part on the
equipment such as screwheads, connectors, control shafts, etc.
When the exposed metallicpart has areturn path to the chassis,
the reading shouldbe between 1M and 5.2M .
When the exposed metal does not have areturn path to the
2

chassis, the reading must be .
Figure 1
1.1.2. Leakage current hot check / (See Figure 1 .)
1. Plug the AC cord directlyinto the AC outlet. Donot use an
isolation transformer for thischeck.
2. Connect a1.5k , 10 watts resistor, inparallel with a0.15 F
capacitors, between each exposed metallicpart on the set and a
good earth ground such as awater pipe, as shownin Figure 1.
3. Use an AC voltmeter, with 1000 ohms/voltor more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallicpart, and measure the voltage at
each point.
5. Reverse the AC plug inthe AC outlet and repeat each of the above
measurements.
6. The potential at anypoint shouldnot exceed 0.75 volts RMS. A
leakage current tester (Simpson Model 229 or equivalent) maybe
used to make the hot checks, leakage current must not exceed 1/2
milliampere. Incase ameasurement isoutside of the limits
specified, there isapossibilityof ashock hazard, and the
equipment shouldbe repaired and rechecked before itisreturned
to the customer.
2. Warning
2.1. Prevention of ElectrostaticDischarge (ESD)to Electrostatic
Sensitive (ES) Devices
Some semiconductor(solidstate) devices canbe damagedeasilybystatic electricity. Such
components commonlyare calledElectrostatic Sensitive (ES) Devices. Examples of typical ES
devices are integratedcircuits and some field-effect transistor-sand semiconductor"chip"
components. The following techniques shouldbe usedtohelpreduce the incidence of
component damage causedbyelectrostatic discharge (ESD).

1. Immediatelybefore handling anysemiconductor component or
semiconductor-equipped assembly, drainoff anyESDon your
bodybytouching aknownearth ground. Alternatively, obtainand
wear acommerciallyavailabledischarging ESDwrist strap, which
shouldbe removed for potential shock reasons prior to applying
power to the unitunder test.
2. After removing an electrical assemblyequipped with ES devices,
place the assemblyon aconductive surface such as aluminum
foil, to prevent electrostaticcharge buildup or exposure of the
assembly.
3. Use onlyagrounded-tipsoldering iron to solder or unsolder ES
devices.
4. Use onlyan anti-staticsolder removal device. Some solder
removal devices not classified as "anti-static(ESDprotected)"
can generate electrical charge sufficient to damage ES devices.
5. Donot use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Donot remove areplacement ES device from its protective
package until immediatelybefore you are readyto install it. (Most
replacement ES devices are packaged with leads electrically
shorted together byconductive foam, aluminum foil or
comparableconductive material).
7. Immediatelybefore removing the protective material from the
leads of areplacement ES device, touch the protective material to
the chassisor circuitassemblyinto which the device will be
installed.
Caution
Besure no power isapplied to the chassisor circuit, and observe
all other safetyprecautions.
8. Minimize bodilymotions when handling unpackaged replacement
ES devices. (Otherwise hamless motion such as the brushing
together of your clothes fabricor the lifting of your foot from a
carpeted floor can generate staticelectricitysufficient to damage
an ES device).

2.3.1. General description about Lead Free Solder(PbF)
The leadfree solderhas beenusedinthe mounting process of all electrical components on the
printedcircuit boards usedforthis equipment inconsidering the globallyenvironmental
conservation.
The normal solderis the alloyof tin(Sn) and lead(Pb). Onthe otherhand, the leadfree solderis
the alloymainlyconsists of tin(Sn), silver(Ag) and Copper(Cu), and the melting point of the
leadfree solderis higherapprox.30 degrees C (86°F) more thanthat of the normal solder.
Definition of PCB LeadFree Solderbeing used
The letterof “PbF” is printedeitherfoil side orcomponents side on the PCB
using the leadfree solder.
(See right figure)
Service caution forrepairwork using LeadFree Solder(PbF)
5

-The lead free solder has to be used when repairing the equipment
for which the lead free solder isused.
(Definition: The letter of “PbF” isprinted on the PCB using the
lead free solder.)
-To put lead free solder, itshouldbe well molten and mixed with the
original lead free solder.
-Remove the remaining lead free solder on the PCB cleanlyfor
soldering of the new IC.
-Since the melting point of the lead free solder ishigher than that of
the normal lead solder, ittakes the longer time to meltthe 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).
RecommendedLeadFree Solder(Service Parts Route.)
-The following 3types of lead free solder are availablethrough the
service parts route.

5.1.3. About DivX DRM
Divx file includes file towhichDRM(Digital Right Management) is appliedand file not applied.
This itemis a content that relates onlyintreating file towhichDRM is applied.
1. Registration Code displayfunction
2. User's registration and approval function
3. Rental management function
1) Registration Code displayfunction
Registration Code is alphanumeric charactersequence 8bytes inputtedas recorderinformation,
incase a use purchases orrent a DivX DRM file ina network.
Registration code is a charactersequence generatedat random, and differs ineachrecorder.

Moreover, Registration code is updatedbynewuserauthentication everif same recorder.
2) User's registration and approval function
-Onlyone user can register for one recorder. Ifuser's registration is
not done with the recorder, DivX filecannot be played back.
-User's registration isperformed onlywhen aDivX DRMfileisfirst
chosen byrecorder
-DivX DRMfilethat can perform user's registration isonlyafilethat
isregistered Registration Code and purchased or rented.
-User authentication isperformed whenever DivX DRMfileisplayed
back.
Error message isdisplayed when failing inuser's registration and
approval.
3) Rental management function
There are purchase file without registration of numberof playback and rental files with
registration of numberof playback as Divx file. Numberof playback of rental file is countedby
the recorder.
Whenrental file is played, remaining numberof times that canbe playedback will be shownto
users, recorderrequests users toinput yes orno.
Following specifications have beeninstalledforthe rental files inthe purpose toclarifythe
count condition of numberof times of playback.
-Conditions on counting number of times of play.
1. When afilewas opened successfully. (Atthe time of playback
start)
2. When you have done review operation from the start. (Skipto file
head)
-Atthistime, remaining number of times that can be played
back and confirmation message [Doyou playreally?] are
displayed.
-When the playback point has been skipped to the top of title,
number of playback isnot counted ifthe top of titlewas not
recognized.
-Even ifthe power failure occurs after start of playback of
rental file, number of times of playback counted at start of the
playback isheldas itis. (Though playback stops bypower
failure, the number of times of playback isnot counted.)

When ithas reached head of title, the playback isended, and
screen becomes DivX menu (There isno resume) and then cursor
islocated on titlethat has been played back.
Then ifthe same filewas continuouslyplayed back, itbegins to
playback from the filehead.
Note:
Above mentionedstoreduserinformation and numberof times of playback are not erasedby
update of firmware orbyinitialization bytest mode.
