your obsolete outlet. Do not defeat the safety
purpose of the polarized plug.
(B) Your product may be equipped with a 3-wire
grounding-type plug, a plug having a third
(grounding) pin. This plug will only fit into a
grounding-type power outlet. This is a safety
If you are unable to insert the plug into the outlet,
contact your electrician to replace your obsolete
outlet. Do not defeat the safety purpose of the
2. Power Sources
Operate your product only from the type of power
source indicated on the marking label. If you are not
sure of the type of power supply to your home,
consult your product dealer or local power company.
If your product is intended to operate from battery
power, or other sources, refer to the operating
Do not overload wall outlets, extension cords, or
integral convenience receptacles as this can result in
a risk of fire or electric shock.
4. Power Cord Protection
Power supply cords should be routed so that they are
not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to
cords at plugs, convenience receptacles, and the
point where they exit from the product.
Slots and openings in the cabinet are provided for
ventilation. To ensure reliable operation of the
product and to protect it from overheating, these
openings must not be blocked or covered.
· Do not block the openings by placing the product

ANTENNA INSTALLATION INSTRUCTIONS
1. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to
the product, be sure the antenna or cable system is
grounded so as to provide some protection against
voltage surges and built-up static charges. Article 810
of the National Electrical Code, ANSI/NFPA 70,
provides information with regard to proper grounding
of the mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of
grounding connectors, location of antenna discharge
unit, connection to grounding electrodes, and
requirements for the grounding electrode.
For added protection for this product during 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 product due
to lightning and power-line surges.
3. 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.

PORTABLE CART WARNING
(Symbol provided by RETAC)
HM-DH100U_Eng.book Page 4 Thursday, August 5, 2004 1:54 PM
Failure to heed the following precautions may result in damage to the VCR, Remote or video cassette.
1. DO NOT place the VCR...
... in an environment prone to extreme temperatures or humidity.
... in direct sunlight.
... in a dusty environment.
... in an environment where strong magnetic fields are generated.
... on a surface that is unstable or subject to vibration.
2. DO NOT block the VCR's ventilation openings or holes.
(If the ventilation openings or holes are blocked by a newspaper or cloth, etc., the heat may not be able to get out.)
3. DO NOT place heavy objects on the VCR or Remote.
4. DO NOT place anything which might spill on top of the VCR or Remote.
(If water or liquid is allowed to enter this equipment, fire or electric shock may be caused.)
5. DO NOT expose the apparatus to dripping or splashing.
6. DO NOT use this equipment in a bathroom or places with water. Also DO NOT place any containers filled with
water or liquids (such as cosmetics or medicines, flower vases, potted plants, cups, etc.) on top of this unit.
7. DO NOT place any naked flame sources, such as lighted candles, on the apparatus.
8. AVOID violent shocks to the VCR during transport.
Moisture in the air will condense on the VCR when you move it from a cold place to a warm place, or under extremely
humid conditions--just as water droplets form on the surface of a glass filled with cold liquid. Moisture condensation
on the head drum will cause damage to the tape. In conditions where condensation may occur, keep the VCR turned
on for a few hours to let the moisture evaporate.
ABOUT HEAD CLEANING
After an extended period of use, the video heads can become dirty, resulting in a loss of picture or sound during
playback. If this happens, clean the video heads by using the optional cleaning tapes.
The heads get dirty in the following cases:
· in an environment prone to extreme temperature or humidity.
· in a dusty environment.
· flaw, dirt or mold on video tapes.
· continuous usage for a long time.
Use a cleaning tape designed specifically for D-VHS video heads (JVC D-VHS video head cleaner DFC-2) to clean the
