4. Setup

4.1 Placement

Position the projector on a stable, level surface or mount it securely. Ensure there is sufficient space around the projector for proper ventilation. The distance from the screen will determine the image size. Adjust the projector's position to achieve the desired image size and focus.

4.2 Connecting Devices

1. Power Connection: Connect the power cord to the projector's AC inlet and then to a grounded electrical outlet.
2. Video Sources:
   • HDMI: Use an HDMI cable to connect your source device (e.g., laptop, Blu-ray player) to an HDMI input port on the projector.
   • VGA (D-Sub): Connect a VGA cable from your computer's VGA output to a VGA input port on the projector.
   • DisplayPort: Connect a DisplayPort cable from your source device to the DisplayPort input.
   • S-Video/Composite: For older devices, use S-Video or composite video cables to connect to the corresponding ports.
3. Audio Sources: If your video source does not transmit audio via HDMI or DisplayPort, or if you prefer external audio, connect audio cables from your source to the projector's audio input ports. The projector has built-in speakers, but external speakers can be connected for enhanced audio.
4. USB: Connect USB devices for presentations or firmware updates.

4.3 Powering On/Off

• To Power On: Press the power button on the projector's control panel or the remote control (if available). The power indicator light will illuminate.
• To Power Off: Press the power button again. A confirmation message may appear. Press the power button a second time to confirm shutdown. Allow the projector to cool down before unplugging it.

5. Operating the Projector

5.1 Basic Operation

• Input Selection: Use the "Input" button on the control panel to cycle through available input sources (HDMI, VGA, DisplayPort, etc.) until your desired source is displayed.
• Menu Navigation: Press the "Menu" button to access the on-screen display (OSD) menu. Use the arrow buttons to navigate through options and the "Enter" button to select. Press "Exit" to close the menu.

5.2 Image Adjustment

• Focus: Rotate the focus ring on the projector lens until the image appears sharp and clear on the screen.
• Zoom: Rotate the zoom ring on the projector lens to adjust the size of the projected image.
• Keystone Correction: If the image appears trapezoidal, use the keystone correction function in the OSD menu to square the image. This can be found under the "Image" or "Setup" menu.
• Lens Shift: Use the lens shift knob (visible on the top view image) to physically move the projected image up, down, left, or right without tilting the projector, minimizing keystone distortion.

5.3 Audio Settings

Adjust the volume using the dedicated volume controls on the control panel or within the OSD menu. You can also select audio input sources if multiple are connected.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your projector.

6.1 Lamp Replacement

The projector lamp has a finite lifespan. When the lamp indicator lights up or the image brightness significantly decreases, the lamp needs replacement. Always use genuine NEC replacement lamps. Refer to the side view image (Figure 3.4) for the lamp access panel location.

1. Power off the projector and unplug the power cord.
2. Allow the projector to cool for at least 60 minutes.
3. Locate and open the lamp cover.
4. Carefully remove the old lamp module and install the new one, ensuring it is securely seated.
5. Close the lamp cover and secure it.
6. Reset the lamp timer in the OSD menu (usually under "Setup" or "Information").

6.2 Air Filter Cleaning/Replacement

Clean the air filter regularly to prevent overheating and maintain image quality. The filter location is typically on the side or bottom of the projector.

1. Power off the projector and unplug the power cord.
2. Locate and remove the air filter cover.
3. Remove the filter and clean it with a soft brush or vacuum cleaner. If heavily soiled or damaged, replace it with a new one.
4. Reinstall the filter and close the cover.
5. Reset the filter timer in the OSD menu (if applicable).

6.3 General Cleaning

• Projector Casing: Wipe the exterior with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
