Safety Precautions (continued)

NOTE

About consumables.

Lamp, LCD panels, polarizors and other optical components, and air filter and cooling fans have a different lifetime in each. These parts may need to be replaced after a long usage time.

•This product isn’t designed for continuous use of long time. In the case of continuous use for 6 hours or more, or use for 6 hours or more every day (even if it isn’t continuous), or repetitious use, the lifetime may be shortened, and these parts may need to be replaced even if one year has not passed since the beginning of using.

•Any inclining use beyond the adjustment range explained in these user’s manuals may shorten the lifetimes of the consumables.

Before turning on the power, make the projector cool down adequately.

After turning the projector off, pushing the restart switch or interrupting of the power supply, make the projector cool down adequately. Operation in a high temperature state of the projector causes a damage of the electrode and un-lighting of the lamp.

Avoid strong rays.

Any strong ray (such as direct rays of the sun or room lighting) onto the remote control sensors could invalidate the remote control.

Avoid radio interference.

Any interfering radiation could cause disordered image or noises.

• Avoid radio generator such as a mobile telephone, transceiver, etc. around the projector.

About displaying characteristic.

The display condition of the projector (such as color, contrast, etc.) depends on characteristic of the screen, because the projector uses a liquid crystal display panel. The display condition can differ from the display of CRT.

• Do not use a polarized screen. It can cause red image.

Turn the power on/off in right order.

To prevent any trouble, turn on/off the projector in right order mentioned below unless specifying.

•Power on the projector before the computer or video tape recorder.

•Power off the projector after the computer or video tape recorder.

Take care not to fatigue your eyes.

Rest the eyes periodically.

Set the sound volume at a suitable level to avoid bothering other people.

•It is better to keep the volume level low and close the windows at night to protect the neighborhood environment.

Connecting with notebook computer

When connecting with notebook computer, set to valid the RGB external image output (setting CRT display or simultaneous display of LCD and CRT).

Please read instruction manual of the notebook for more information.

ED-X42 specifications

The Hitachi ED-X42 is a highly regarded projector designed to meet the diverse needs of both educational and corporate environments. Combining advanced technology with user-friendly features, the ED-X42 stands out for its versatility and performance.

One of the main features of the Hitachi ED-X42 is its impressive brightness, rated at 4200 ANSI lumens. This high brightness level ensures that images and presentations remain clear and visible even in well-lit rooms. Additionally, the projector boasts a native XGA resolution of 1024 x 768, delivering detailed and sharp visuals that enhance the viewing experience.

The ED-X42 employs a 3LCD technology, which allows it to produce vibrant and accurate colors. This technology ensures that color reproduction is consistent and enhances the overall quality of the projected images. Coupled with a contrast ratio of 2000:1, the projector provides deep blacks and bright whites, ensuring that both text and images stand out.

Another noteworthy characteristic of the Hitachi ED-X42 is its comprehensive connectivity options. The projector features multiple input sources, including HDMI, VGA, and composite video, making it compatible with various devices such as laptops, Blu-ray players, and document cameras. This versatility is particularly beneficial in a classroom or meeting room setting, where different users may need to connect their devices.

The ED-X42 is also equipped with integrated audio capabilities, featuring built-in speakers that deliver clear sound without the need for external speakers. This makes it suitable for small to medium-sized venues where additional audio equipment might not be feasible.

Furthermore, the projector includes a relatively short throw ratio, allowing it to project large images from a short distance. This feature is particularly useful in smaller rooms where space is limited, enabling users to maximize the available area while still achieving a large image size.

In terms of maintenance, the Hitachi ED-X42 utilizes a long-lasting lamp that can operate for approximately 5,000 hours in normal mode and up to 10,000 hours in eco mode. This extended lamp life reduces the frequency and cost of replacements, adding to the projector's overall value.

Finally, the ED-X42 is designed with user-friendly features such as an intuitive remote control and an easy-to-navigate menu, making setup and operation straightforward for users of all skill levels. With its combination of advanced technologies, practical features, and robust performance, the Hitachi ED-X42 remains a popular choice for a wide range of applications.
