1. Plug the AC cord directly into the AC outlet. Do not use an

isolation transformer for this check.

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.

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. After servicing, see to it that all the protective devices such

as insulation barriers, insulation papers shields are properly installed.

3. Use an AC voltmeter, with 1000 ohms/volt or more

sensitivity, to measure the potential across the resistor.

4. After servicing, make the following leakage current checks

to prevent the customer from being exposed to shock hazards.

LEAKAGE CURRENT HOT CHECK

4. Check each exposed metallic part, and measure the

voltage at each point.

5. Reverse the AC plug in the AC outlet and repeat each of the

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.

1. Unplug the AC cord and connect a jumper between the two

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

ELECTROSTATIC SENSITIVE (ES) DEVICES

protected)" can generate electrical charge sufficient 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-sand semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). 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).

before handling any semiconductor 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.

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.

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.

8. Minimize bodily motions when handling unpackaged

replacement ES devices. (Otherwise hamless 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).

3. Use only a grounded-tip soldering iron to solder or unsolder

4. Use only an anti-static solder removal device. Some solder

removal devices not classified as "anti-static (ESD

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.)

ABOUT DivX DRM Divx file includes file to which DRM(Digital Right Management) is applied and file not applied. This item is a content that relates only in treating file to which DRM is applied.

1. Registration Code display function

2. User’s registration and approval 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.

• 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.

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.
