1 Safety precautions
1.1 General guidelines
1. 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. After servicing, see to it that 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 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 screwheads, connectors, control shafts, etc. When the exposed metallic
part has a return path to the chassis, the reading should be between 1MΩand 5.2MΩ.
When the exposed metal does not have a return path to the chassis, the reading must be .
Figure 1
1.1.2 Leakage current hot check
(See Figure 1 .)
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 the AC outlet and repeat each of the 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 Prevention of Electrostatic
Discharge (ESD) to Electrostatic
Sensitive (ES) Devices
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).
1. Immediately 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.
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. 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).

4 Handling the Lead-free Solder
4.1 About lead free solder (PbF)
Distinction of PbF P.C.B.:
P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.
Caution:
zPb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C)
higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please
set it to 700 ± 20°F (370 ± 10°C).
zPb free solder will tend to splash when heated too high (about 1100°F/600°C).
zWhen 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.

6 New Feature
6.1 Quick start function(REC)
1. General
A few seconds after tuning on the unit,you can start recording to DVD-RAM,HDD.
You can switch the operation of this function (ON/OFF) on the menu screen. .
2. Quick start(REC) principle
In the power-off at Quick start, only power supplies for video IC,tuner and storage media are cut off.
When the REC button is pushed a few second after the power button is pushed, Audio and Video data
are stored in
DDR SDRAM before a storage media(DVD-RAM or HDD) preparation.
*Preparation time →DVD-RAM: Fabout 8seconds
HDD: about 18seconds
After a storage media(DVD-RAM or HDD) preparation,Audio and Video data are transfer from DDR
SDRAM to the storage media.

7 Taking out the Disc from RAM-
Drive Unit when the Disc cannot be
ejected by OPEN/CLOSE button
7.1 Forcible Disc Eject
7.1.1 When the power can be turned off.
1. Turn off the power and press [STOP] [CH UP] keys on the front panel simultaneously for 5 seconds.
7.1.2 When the power can not be turned off.
1. Press [POWER] key on the front panel for over 10 seconds to turn off the power forcibly, and press [STOP] [CH
UP] keys on the front panel simultaneously for 5 seconds.
7.2 When the Forcible Disc Eject can not be
done.
1. Turn off the power and pull out AC cord.
2. Remove the Top Case.
3. Remove the Front Panel.
4. Remove 4 screws and Upper Base Unit from DVD-RAM Drive.
5. Take out the disc and put the Opener Roller on fully position for direction of Arrow.
6. Put the Upper Base Unit so that the Opener Roller is inserted into the groove.
7. Check Opener Roller is seen through the Opener position Checking Hole, and tighten 4 screws.
