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

1MΩand 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 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.

1 SAFETY PRECAUTIONS

DMR-EX75EG / DMR-EX75EC / DMR-EX75EB / DMR-EX85EG / DMR-EX85EB

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).

ELECTROSTATIC SENSITIVE (ES) DEVICES

DMR-EX75EG / DMR-EX75EC / DMR-EX75EB / DMR-EX85EG / DMR-EX85EB

2.2. 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 (DVDs)/780 nm (CDs)

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(DVDs)/780 nm (CDs)

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.

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.

RFKZ03D01K-----------(0.3mm 100g Reel)

RFKZ06D01K-----------(0.6mm 100g Reel)

RFKZ10D01K-----------(1.0mm 100g Reel)

Note

·Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
