4. Setup

Projector Placement

Adjust the distance from the screen to achieve the desired image size. The 1.6x zoom allows for a larger image from a shorter distance or a smaller image from a longer distance without moving the projector.

Connecting Devices

1. Power Connection: Connect the power cord to the projector's power inlet and then to a grounded electrical outlet.
2. Video Source:
   • For HDMI devices (e.g., Blu-ray player, laptop): Connect an HDMI cable from your device to one of the HDMI ports on the projector.
   • For VGA devices (e.g., older laptops): Connect a VGA cable from your device to a VGA port on the projector. If audio is also required, connect a separate 3.5mm audio cable from your device to an Audio In port on the projector.
   • For MHL compatible mobile devices: Connect an MHL cable to the designated HDMI/MHL port.
3. Audio Output (Optional): If using external speakers, connect an audio cable from the projector's Audio Out port to your sound system.

Powering On/Off

• To Power On: Press the power button on the projector's control panel or the remote control. The power indicator light will turn blue.
• To Power Off: Press the power button twice. The projector will enter a cooling down cycle before completely shutting off. Do not unplug the projector during the cooling cycle.

5. Operating the Projector

Basic Operation

• Source Selection: Use the 'Source' button on the remote or control panel to cycle through available input sources (HDMI1, HDMI2/MHL, VGA1, VGA2).
• Menu Navigation: Press the 'Menu' button to access the On-Screen Display (OSD). Use the arrow keys to navigate and 'Enter' to select options.
• Volume Control: Use the volume buttons on the remote control to adjust the audio output from the built-in speaker or Audio Out port.

Image Adjustments

• Focus and Zoom: Rotate the focus and zoom rings on the projector lens to achieve a sharp and appropriately sized image.
• Keystone Correction: If the image appears trapezoidal, use the 'Keystone' function in the OSD menu or the dedicated button on the remote to correct the image shape. The EH416 supports ±40° vertical keystone correction.
• Vertical Lens Shift: This feature allows you to physically move the image up or down without tilting the projector, minimizing keystone distortion. Adjust the lens shift dial located near the lens.
• Wall Color Adjustment: Access this feature in the OSD menu to compensate for the color of your projection surface (e.g., blackboard, light yellow wall). This helps maintain accurate color reproduction even on non-white walls.
• sRGB Color Profile: For the most accurate and vibrant colors, especially when connecting to a PC, Mac, or sRGB compatible source, select the sRGB picture mode in the OSD. This profile adheres to the Rec. 709 HDTV specification.
• Edge Mask: This function, found in the OSD, helps to refine the edges of the projected image, eliminating any soft or jagged appearance on the border.

6. Maintenance

Cleaning the Projector

• Lens: Use a soft, lint-free cloth specifically designed for optical lenses. Do not use abrasive cleaners.
• Casing: Wipe the projector casing with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth with a mild detergent, then wipe dry.
• Air Vents: Regularly check and clean the air vents to prevent dust buildup, which can lead to overheating. Use a soft brush or compressed air.

Lamp Care

The projector lamp has a finite lifespan. When the lamp life is nearing its end, a warning message may appear on the screen. Refer to the full user manual on the included CD-ROM for detailed instructions on lamp replacement. Always use genuine Optoma replacement lamps to ensure optimal performance and safety.
