1 Safety Precautions
1.1. General Guidelines
1. IMPORTANT SAFETY NOTICE
There are special components used in this equipment
which are important for safety. These parts are marked by
in the Schematic Diagrams, Circuit Board Layout,
Exploded Views and Replacement Parts List. It is essen-
tial that these critical parts should be replaced with manu-
facturer’s specified parts to prevent X-RADIATION,
shock, fire, or other hazards. Do not modify the original
design without permission of manufacturer.
2. An Isolation Transformer should always be used during
the servicing of AC Adaptor whose chassis is not isolated
from the AC power line. Use a transformer of adequate
power rating as this protects the technician from acci-
dents resulting in personal injury from electrical shocks. It
will also protect AC Adaptor from being damaged by acci-
dental shorting that may occur during servicing.
3. When servicing, observe the original lead dress. If a short
circuit is found, replace all parts which have been over-
heated or damaged by the short circuit.
4. After servicing, see to it that all the protective devices
such as insulation barriers, insulation papers shields are
properly installed.
5. After servicing, make the following leakage current
checks to prevent the customer from being exposed to
shock hazards.
1.2. 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 metal-
lic cabinet part on the equipment such as screwheads,
connectors, control shafts, etc. When the exposed metal-
lic part has a return path to the chassis, the reading
should be between 1 MΩand 5.2 MΩ. When the exposed
metal does not have a return path to the chassis, the
reading must be infinity.
1.3. 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 1.5 kΩ, 10 W resistor, in parallel with a 0.15 μF
capacitor, between each exposed metallic part on the set
and a good earth ground, as shown in Figure 1.
3. Use an AC voltmeter, with 1 kΩ/V or more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallic part, and measure the volt-
age 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 V RMS.
A leakage current tester (Simpson Model 229 or equiva-
lent) may be used to make the hot checks, leakage cur-
rent must not exceed 1/2 mA. 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.

2Warning
2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically
Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-
trostatically Sensitive (ES) Devices.
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 alumi-
num 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 antistatic solder removal device. Some solder removal devices not classified as "antistatic (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 compara-
ble 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 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 (ESD) suf-
ficient to damage an ES device).

2.2. Caution for AC Cord
(For the Saudi Arabia, Kuwait
and Africa)
2.2.1. Information for Your Safety
IMPORTANT
Your attention is drawn to the fact that recording of pre-
recorded tapes or discs or other published or broadcast
material may infringe copyright laws.
WARNING
To reduce the risk of fire or shock hazard, do not expose
this equipment to rain or moisture.
CAUTION
To reduce the risk of fire or shock hazard and annoying
interference, use the recommended accessories only.
FOR YOUR SAFETY
DO NOT REMOVE THE OUTER COVER
To prevent electric shock, do not remove the cover. No user
serviceable parts inside. Refer servicing to qualified service
personnel.
2.2.2. Caution for AC Mains Lead
For your safety, please read the following text carefully.
This appliance is supplied with a moulded three-pin mains plug
for your safety and convenience.
A 5-ampere fuse is fitted in this plug.
Should the fuse need to be replaced please ensure that the
replacement fuse has a rating of 5 amperes and it is approved
by ASTA or BSI to BS1362
Check for the ASTA mark or the BSI mark on the body of the
fuse.
If the plug contains a removable fuse cover you must ensure
that it is refitted when the fuse is replaced.
If you lose the fuse cover, the plug must not be used until a
replacement cover is obtained.
A replacement fuse cover can be purchased from your local
Panasonic Dealer.
If the fitted moulded plug is unsuitable for the socket outlet in
your home then the fuse should be removed and the plug cut
off and disposed of safety.
There is a danger of severe electrical shock if the cut off plug is
inserted into any 13-ampere socket.
If a new plug is to be fitted please observe the wiring code as
shown below.
If in any doubt, please consult a qualified electrician.
2.2.2.1. Important
The wires in this mains lead are coloured in accordance with
the following code:
As the colours of the wires in the mains lead of this appliance
may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
The wire which is coloured BLUE must be connected to the ter-
minal in the plug which is marked with the letter N or coloured
BLACK.
The wire which is coloured BROWN must be connected to the
terminal in the plug which is marked with the letter L or coloured
RED.
Under no circumstances should either of these wires be con-
nected to the earth terminal of the three pin plug, marked with
the letter E or the Earth Symbol.
2.2.2.2. Before Use
Remove the Connector Cover as follows.
2.2.2.3. How to Replace the Fuse
1. Remove the Fuse Cover with a screwdriver.
2. Replace the fuse and attach the Fuse cover.

2.3. Precaution of Laser Diode

2.4. Static Electricity Protection Measures
• The laser diode in the traverse unit (optical pick-up) 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 traverse unit (optical pick-up).
2.5. Ground for electrostatic breakdown prevention
• As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working environ-
ment.
Repair in the working environment that is grounded.
2.5.1. Work table grounding
• Put a conductive material (sheet) or steel sheet on the area where the traverse unit (optical pick-up) is placed, and ground the
sheet.
2.5.2. Human body grounding
• Use the anti-static wrist strap to discharge the static electricity from your body.
2.5.3. When exchange the Drive
• Before remove the ESD prevention bag, make sure to use the anti-static wrist strap to discharge the static electricity when
replace the Drive.
Note:
The ESD prevention bag is used to replace the original short-circuit point.
It can be removed while placing the Drive.
