DOC avis de conformation

• WARNING •

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
– Reorient or relocare the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver

is connected.

– Consult the dealer or an experienced radio/TV technician for help.

The IDC-3000 converts NTSC video signals into scan-doubled signals.
This scan converter can be used with a multi-synchronous scan monitor or
projectors having a minimum of 31.5 kHz horizontal scanning capability to
provide high-quality images.
The IDC-3000 can be also connected to a document camera, conventional

VCR, video disc player, S-Video recorder, or video camera.

FEATURES

v Motion adaptive 3-dimensional Y/C separation circuit greatly reduces

cross talk (dot interference/cross color).

v Motion adaptive 3-dimensional scanning line interpolation circuit pro-

vides a reduction of line flicker and an increase of vertical resolution.

v Two-mode digital video noise reduction circuit greatly improves the

signal-to-noise ratio of the signal.

v Forced (non adaptive) still screen mode provides a still image without

erroneous operation of the operation detection circuit. (This is useful
with the images of document cameras, etc.)

v Equipped with a demonstration split function for processing artificial

interlace and switching off 3-dimensional Y/C separation processing
the right half of the screen.

v PC-CONTROL connector permits control of a personal computer.

Warnings and Safety Precaution

The NEC IDC-3000 is designed and manufactured to provide long, trouble­free service. No maintenance other than cleaning is required. Use a soft cloth
and if necessary, mild detergent. Do not use commercial spray cleaners
which may damage the surface. In case of damage, arrange for repairs at an
authorized NEC Service Center.

For operating safety and to avoid damage to the unit, read carefully and
observe the following instructions.

To avoid shock and fire hazards:

1. Provide adequate space for ventilation to avoid internal heat build-up. If
you enclose the unit in a cabinet or rack, be sure there is adequate space
at the top of the unit to allow heated air to rise and escape.

2. Do not use the power cord polarized plug with extension cords or outlets
unless the prongs can be completely inserted.

3. Do not expose unit to rain or moisture.

4. Avoid damage to the power cord, and do not attempt to modify the power
cord.

5. Unplug unit during electrical storms or if unit will not be used over a long
period.

6. Do not open the cabinet which has potentially dangerous high voltage
components inside. If the unit is damaged in this way the warranty will be
void. Moreover, there is a serious risk of electric shock.

2

7. Do not attempt to service or repair the unit. NEC is not liable for any bodily
harm or damage caused if unqualified persons attempt service or open
the cabinet. Refer all service to authorized NEC Service Centers.

To avoid damage and prolong operating life:

1. Use only with 120V 60Hz AC power supply.

2. Handle the unit carefully when moving and do not drop.

3. Locate set away from heat, excessive dust, and direct sunlight.

4. Protect the inside of the unit from liquids and small metal objects. In
case of accident, unplug the unit and have it serviced by an authorized
NEC Service Center.

5. Unplug unit before cleaning. Use only a soft cloth and mild detergent.
Commercial household sprays and cleaners may damage the cabinet.

WARNING

Unqualified persons should under no circumstances remove the cabinet of
the unit to make internal adjustments. The warranty is void if the unit is
damaged in this way. Moreover, there is a serious risk of electric shock. If you
have service difficulties, call your dealer.

Mises en garde et précautions de sécurité

Le IDC-3000 NEC a été conçus et fabriqués pour assurer une longue durée de service
sans problèmes. Aucun entretien à l’exception du nettoyage n’est nécessaire. Utiliser
un chiffon doux et un détergent doux, si nécessaire. Ne pas utiliser des aérosols de
nettoyage du commerce qui risquent d’endommager la surface de cet appareil. Si
l’appareil est endommagé, confier les travaux de réparation à un centre de service
agréé NEC.

Pour un fonctionnement sûr et afin d’éviter d’endommager l’appareil, lire attentivement
et respecter les instructions suivantes.

Afin d’éviter tout risque d’électrocution et d’incendie:

1. Réserver un espace libre suffisant pour la ventilation afin d’éviter une accumulation
de chaleur interne. Si l’appareil est logé dans un coffret ou sur une étagère,
s’assurer qu’il y a un espace libre suffisant pour la dissipation de la chaleur.

2. Ne pas utiliser la fiche polarisée du cordon d’alimentation avec des prolongateurs
ou des prises de courant, sauf si les lames peuvent être insérées à fond.

3. Ne pas exposer à la pluie ou à l’humidité.

4. Eviter d’endommager le cordon d’alimentation, et ne pas modifier le cordon
d'alimentation.

5. Débrancher l’appareil pendant les tempêtes ou si l’appareil n’est pas utilisé pendant
une longue période.

6. Ne pas ouvrir le coffret. Des composants de haute tension se trouvent à l’intérieur.
Si l’appareil est endommagé de cette manière, la garantie devient caduque. De plus,
il y a risque d’électrocution.

7. Ne pas essayer de réparer ou entretenir l’appareil soi-même. NEC ne saura être tenu
pour responsable pour toute blessure ou dommage causé par des personnes non
qualifiées qui essayent de réparer ou d’ouvrir le coffret. Confier toute réparation à
un centre de service agréé NEC.

Pour éviter des dommages et prolonger la durée de service de l’appareil:

1. N’utiliser qu’une source d’alimentation de 120 V 60 Hz CA.

2. Manipuler l’appareil avec soin pendant son déplacement et ne pas le faire tomber.

3. Eloigner l’appareil des endroits chauds, très poussiéreux et exposés en plein soleil.

4. Eviter que des liquides et des petits objets métalliques pénètrent à l’intérieur de
l’appareil. En cas d’accident, débrancher l’appareil et le confier à un centre de
service agréé NEC.

5. Débrancher l’appareil avant le nettoyage. Utiliser seulement un chiffon doux et un
détergent doux.

Des aérosols et produits de nettoyage disponibles dans le commerce risquent
d’endommager le coffret.

AVERTISSEMENT

Le coffret ne doit pas être enlevé par un personnel non qualifié pour faire les réglages
internes. La garantie devient caduque si l’appareil est endommagé de cette manière.
De plus, il y a risque d’électrocution. En cas de problèmes de réparation contacter votre
revendeur.

less effect because the 3-dimensional Y/C separation processing is not
performed unless the NTSC indicator is lit.
