3.If the circuit is changed or modified, this information will be
followed by supplement service manual to be filed with
original service manual.
4.Adjustment procedures, Disassembly Procedures and
Assembly Procedures for VCR Mechanism Chassis are
separate volume from this service manual. Please refer to
the service manual for R4 Mechanism Chassis for EURO
model (MAD0403002C2).
2 SAFETY PRECAUTIONS
2.1. 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.
2.1.1. 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
1MΩand 5.2MΩ.
When the exposed metal does not have a return path to
the chassis, the reading must be infinity.
Figure 1
2.1.2. 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 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.

DMR-EH80VEG / DMR-EH80VEB

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 unpacked
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).

TO ELECTROSTATIC SENSITIVE (ES) DEVICES

DMR-EH80VEG / DMR-EH80VEB

This model uses lead free solder (PbF). For repair use only
lead free handsolder.
Caution:
Pb free solder has a higher melting point than standard
solder; Typically the melting point is 50 - 70ｰF (30 - 40ｰC)
higher. Please use a high temperature soldering iron. In
case of the soldering iron with temperature control, please
set it to 700 +/-20ｰF (370 +/-10ｰC). Pb free solder will tend
to splash when heated too high (about 1100ｰF/ 600ｰC).
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.
4 PRECAUTION OF LASER DIODE
CAUTION: ACHTUNG:
This product utilizes a laser diode with the unit turned “on”,
invisible laser radiation is emitted from the pickup lens.
Wave length: 662 nm/795 nm
Maximum output radiation power from pickup: 100µ W/VDE.
Laser radiation from the pickup lens is safety level, but be sure
the followings:
Dieses Produkt enthält eine Laserdiode.
Im eingeschalteten Zustand wird unsichtbare Laserstrahlung von der
Lasereinheit ausgestrahlt.
Wellenlänge: 662 nm/795 nm
Maximale Strahlungsleistung der Lasereinheit: 100µ W/VDE.
Die Strahlung der eingeschalteten Lasereinheit ist ungefährlich, wenn
folgende Punkte beachtet werden:
1. Do not disassemble the optical pickup unit, since radiation
from exposed laser diode is dangerous. 1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten Laserdiode gefährlich ist.
2. Do not adjust the variable resistor on the pickup unit.
It was already adjusted. 2. Den werksseitig justierten Einstellregler der Lasereinheit nicht verstellen.
3. Do not look at the focus lens using optical instruments. 3. Nicht in die Fokussierlinse blicken.
4. Recommend not to look at pickup lens for a long time. 4. Auch nicht mit optischen Instrumenten in die Fokussierlinse blicken.
5 ABOUT LEAD FREE SOLDER (PbF)

DMR-EH80VEG / DMR-EH80VEB

The laser diode in the traverse unit (optical pickup) may brake
down due to static electricity of clothes or human body. Use
due caution to electrostatic breakdown when servicing and
handling the laser diode.
6.1. GROUNDING FOR
ELECTROSTATIC
BREAKDOWN PREVENTION
Some devices are using the optical pickup (laser diode) and the
optical pickup will be damaged by static electricity in the
working environment. Proceed servicing works under the
working environment where grounding works is completed.
6.1.1. WORKTABLE GROUNDING
1.Put a conductive material (sheet) or iron sheet on the area
where the optical pickup is placed, and ground the sheet.
6.1.2. HUMAN BODY GROUNDING
1.Use the anti-static wrist strap to discharge the static
electricity form your body.
6.1.3. HANDLING OF OPTICAL PICKUP
1.To keep the good quality of the optical pickup maintenance
parts during transportation and before installation, the both
ends of the laser diode are short-circuit. After replacing the
parts with new ones, remove the short circuit according to
the correct procedure.
2.Do not use a tester to check the laser diode for the optical
pickup. Failure to do so will damage the laser diode due to
the power supply in the tester.
6.2. HANDLING PRECAUTIONS
FOR OPTICAL PICK-UP UNIT
The laser diode in the optical pick-up unit may break down due
to potential difference caused by static electricity of clothes or
human body.
So be careful of electrostatic breakdown during repair of the
optical pick-up unit.
6.2.1. HANDLING OF OPTICAL PICK-UP
UNIT
1.The optical pick-up unit has high precision extremely
sensitive structure. Be careful not to apply excessive shock.
