IMPORTANT SAFEGUARDS
13. LIGHTNING
To protect your unit from a lightning storm, or when it is left unattended and unused for long periods of time,
unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the
unit due to lightning and power line surges.
14. POWER LINES
An outside antenna system should not be located in the vicinity of overhead power lines or other electric
light or power circuits, or where it can fall into such power lines or circuits. When installing an outside
antenna system, extreme care should be taken to keep from touching such power lines or circuits, as
contact with them might be fatal.
15. OVERLOADING
Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric shock.
16. OBJECT AND LIQUID ENTRY
Do not push objects through any openings in this unit, as they may touch dangerous voltage points or short
out parts that could result in fire or electric shock. Never spill or spray any type of liquid into the unit.
17. OUTDOOR ANTENNA GROUNDING
If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is
grounded to provide some protection against voltage surges and built-up static charges, Section 810 of the
National Electrical Code, ANSI/NFPA 70, provides information with respect to proper grounding of the mast
and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding
conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for
the grounding electrode.
18. SERVICING
Do not attempt to service this unit yourself as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.
19. DAMAGE REQUIRING SERVICE
Unplug this unit from the wall outlet and refer servicing to qualified service personnel under the following
conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the unit.
c. If the unit has been exposed to rain or water.
d. If the unit does not operate normally by following the operating instructions. Adjust only those
controls that are covered by the operating instructions, as an improper adjustment of other controls
may result in damage and will often require extensive work by a qualified technician to restore the
unit to its normal operation.
e. If the unit has been dropped or the cabinet has been damaged.
f . When the unit exhibits a distinct change in performance, this indicates a need for service.
20. REPLACEMENT PARTS
When replacement parts are required, be sure the service technician uses replacement parts specified by
the manufacturer or those that have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock or other hazards.
21. SAFETY CHECK
Upon completion of any service or repairs to this unit, ask the service technician to perform safety checks to
determine that the unit is in proper operating condition.
22. HEAT
The product should be situated away from heat sources such as radiators, heat registers, stoves, or other
products (including amplifiers) that produce heat.
23. DISC TRAY
Keep your fingers well clear of the disc tray as it is closing. It may cause serious personal injury.
24. CONNECTING
When you connect the product to other equipment, turn off the power and unplug all of the equipment from
the wall outlet. Failure to do so may cause an electric shock and serious personal injury. Read the owner's
manual of the other equipment carefully and follow the instructions when making any connections.

Introduction

Precautions

Notes on handling
When shipping the DVD/VCR, the original shipping
carton and packing materials come in handy. For
maximum protection, repack the unit as it was
originally packed at the factory.
Do not use volatile liquids, such as insect spray, near
the DVD/VCR. Do not leave rubber or plastic
products to contact the DVD/VCR for a prolonged
period. They will leave marks on the finish.
The top and rear panels of the DVD/VCR may
become warm after a long period of use. This is not a
malfunction.
When the DVD/VCR is not in use, be sure to remove
the disc and the video cassette turn off the power.
If you do not use the DVD/VCR for a long period, the
unit may not function properly in the future. Turn on
and use the DVD/VCR occasionally.
Notes on locating
Place the DVD/VCR on a level surface. Do not use it
on a shaky or unstable surface such as a wobbling
table or inclined stand. The loaded disc or the video
tape may become dis-aligned and damage the DVD/
VCR.
When you place this DVD/VCR near a TV, radio, or
VCR, the playback picture may become poor and the
sound may be distorted. In this case, place the DVD/
VCR away from the TV, radio, or VCR.
Notes on cleaning
Use a soft, dry cloth for cleaning.
For stubborn dirt, soak the cloth in a weak detergent
solution, wring well and wipe. Use a dry cloth to wipe
it dry.
Do not use any type of solvent, such as thinner and
benzine, as they may damage the surface of the
DVD/VCR.
If you use a chemical saturated cloth to clean the unit,
follow that product's instructions.
To obtain a clear picture
The DVD/VCR is a high technology, precision device. If
the video head, the head drum, the optical pick-up lens
or disc drive parts are dirty or worn down, the picture
quality will deteriorate. To obtain a clear picture, we
recommend regular inspection and maintenance
(cleaning or parts replacement) every 1,000 hours of
use depending on the operating environment. For
details, contact your nearest dealer.

Notes on moisture condensation
Moisture condensation damages the DVD/VCR.
Please read the following carefully.
Moisture condensation occurs, for example, when you
pour a cold drink into a glass on a warm day. Drops of
water form on the outside of the glass. In the same way,
moisture may condense on the head drum or the optical
pick-up lens inside this unit, one of the most crucial
internal parts of the DVD/VCR.
Tape
Head drum
Moisture condensation occurs during the
following cases.
When you bring the DVD/VCR directly from a cold
place to a warm place.
When you use the DVD/VCR in a room where you
just turned on the heater, or a place where the cold
wind from the air conditioner directly hits the unit.
In summer, when you use the DVD/VCR in a hot and
humid place just after you move the unit from an air
conditioned room.
When you use the DVD/VCR in a humid place.
Do not use the DVD/VCR when moisture
condensation may occur.
If you use the DVD/VCR in such a situation, it may
damage discs and internal parts. Remove the disc or
the video tape, connect the power cord of the DVD/
VCR to the wall outlet, turn on the DVD/VCR, and
leave it for two or three hours. After two or three
hours, the DVD/VCR will have warmed up and
evaporated any moisture. Keep the DVD/VCR
connected to the wall outlet and moisture
condensation will seldom occur.

IMPORTANT SAFEGUARDS
25. LASER BEAM
Do not look into the opening of the disc tray or ventilation opening of the product to see the source of the
laser beam. It may cause sight damage.
26. DISC
Do not use a cracked, deformed, or repaired disc. These discs are easily broken and may cause serious
personal injury and product malfunction.
27. NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC that
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be con-
nected to the grounding system of the building, as close to the point of cable entry as practical.

CONDENSATION
Moisture will form in the operating section of the DVD/VCR if the player is brought from cool surroundings into a
warm room or if the temperature of the room rises suddenly. When this happens, the DVD/VCR's performance
will be impaired.
To prevent this, let the DVD/VCR stand in its new surroundings for about an hour before switching it on, or make
sure that the room temperature rises gradually.
Condensation may also form during the summer if the DVD/VCR is exposed to the breeze from an air
conditioner. In such cases, change the location of the DVD/VCR.

Notes:
• Never connect the AC line cord plug to other than the specified
voltage (120V 60Hz). Use the attached power cord only.
• If the polarized AC cord does not fit into a non-polarized AC
outlet, do not attempt to file or cut the blade. It is the user's
responsibility to have an electrician replace the obsolete outlet.
