Important Information

Fire and Shock Precautions

1.Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 4 inches (10 cm) of space between your projector and a wall.

2.Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to retrieve any objects that might fall into your projector.

Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified NEC service personnel.

3.Do not place any liquids on top of your projector.

4.Do not look into the lens while the projector is on. Serious damage to your eyes could result.

5.Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can cause unpredictable outcome such as fire or injury to the eyes.

6.Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to melting of the cap and possibly burning your hands due to the heat emitted from the light output.

7.The projector is designed to operate on a power supply of 100-240 V 50/60 Hz AC. Ensure that your power supply fits this requirement before attempting to use your projector.

8.Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire.

9.If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.

10.Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.

CAUTION

•Do not try to touch the ventilation outlet on the left side (when seen from the front) as it can become heated while the projector is turned on.

•Do not use the tilt-foot for purposes other than originally intended.

Misuses such as gripping the tilt-foot or hanging on the wall can cause damage to the projector.

•Do not send the soft carrying case by parcel delivery service or cargo shipment. The projector inside the soft carrying case could be damaged. (However, it is possible to use it as a carriercase on board.)

•Enable High-Speed Fan mode if you continue to use the projector for consecutive days. (From the menu, select [Setup] → [Page 4] → [Fan Mode].)

•Do not unplug the power cable from the wall outlet under any one of the following circumstances. Doing so can cause damage to the projector:

*While the Hour Glass icon appears.

*While the cooling fans are running. (The cooling fans continue to work for 10 seconds after the projector is turned off).

One of the key features of the VT770 is its native XGA resolution (1024 x 768 pixels), which ensures clear and detailed images. It utilizes a 3LCD technology, which contributes to bright, vibrant colors and high light output. With a brightness rating of 2800 ANSI lumens, it performs exceptionally well in diverse lighting conditions, making it suitable for medium to large-sized rooms without compromising image quality.

The VT770 offers a contrast ratio of up to 600:1, which enhances the distinction between the brightest whites and the deepest blacks. This feature is particularly beneficial for presentations that involve detailed graphs or images, as it allows for precise visual communication. The projector’s lamp life extends to approximately 6000 hours in eco mode, thus reducing operational costs and the frequency of replacements.

Connectivity is another area where the VT770 excels. It comes equipped with multiple input options, including VGA, composite video, S-video, and HDMI. This flexibility allows users to connect various devices such as laptops, DVD players, and video game consoles seamlessly. Additionally, the projector supports optional wireless connectivity, enabling presentations without the hassle of cables.

User-friendly features are integrated into the VT770, including an intuitive control panel and remote control, allowing easy adjustments and navigation through settings. The projector also incorporates keystone correction, which aids in aligning the image and ensuring a squared display despite the projection angles.

Another distinguishing characteristic of the VT770 is its lightweight and portable design, making it an excellent choice for professionals on the go. It can be easily transported between locations, enabling spontaneous presentations without the need for extensive setup time.

In conclusion, the NEC VT770 is a feature-packed projector that combines high-quality imaging with flexible connectivity and user-friendly operation. Its suitability for educational and business presentations makes it an invaluable tool for professionals seeking reliable performance and portability.
