4. Setup
4.1. Placement
Position the projector on a stable, flat surface or mount it securely to a ceiling. Ensure there is adequate space around the projector for ventilation. The distance from the screen will determine the image size. Refer to the specifications section for throw ratio details.
4.2. Connecting Power
Connect the supplied power cord to the projector's power inlet and then to a grounded electrical outlet. The power LED will illuminate, indicating standby mode.
4.3. Connecting Video Sources
Connect your video source (e.g., computer, Blu-ray player, cable box) to the appropriate input port on the projector's rear panel using a compatible cable. For best quality, use the HDMI input.
- HDMI: Connect an HDMI cable from your source to the projector's HDMI port.
- VGA: Connect a VGA cable from your computer to either the Computer 1 or Computer 2 port.
- Composite/S-Video: Connect the respective cable for older video sources.
4.4. Connecting Audio
If using VGA, Composite, or S-Video inputs, connect an audio cable from your source's audio output to one of the projector's 3.5mm Audio In ports. HDMI carries both video and audio, so a separate audio connection is not typically needed for HDMI sources.
4.5. Adjusting Focus and Zoom
After powering on the projector and displaying an image, rotate the Focus ring around the lens until the image is sharp and clear. Use the Zoom ring to adjust the image size to fit your screen.
5. Operation
5.1. Powering On/Off
- To Power On: Press the Power button on the projector's top panel or the remote control. The power indicator will turn green.
- To Power Off: Press the Power button twice. The projector will enter a cooling cycle, and the power indicator will turn red (standby) once complete.
5.2. Selecting Input Source
Press the "Source" button on the projector or remote control repeatedly to cycle through available input sources (HDMI, VGA1, VGA2, S-Video, Video). The projector will automatically detect an active signal if "Auto Source" is enabled in the menu.
5.3. Menu Navigation
Press the "Menu" button to access the On-Screen Display (OSD) menu. Use the directional arrows to navigate through menu options and the "Enter" button to select. Press "Menu" again to exit.
5.4. 3D Content Playback
The IN112a supports 3D content from Blu-ray players, cable boxes, dish services (over HDMI), and PC-based 3D content at 120Hz. To view 3D content, you will need 144 Hz DLP Link 3D glasses (sold separately).
- Ensure your 3D source is connected via HDMI.
- Play 3D content from your source.
- Turn on your 144 Hz DLP Link 3D glasses. The projector should automatically detect the 3D signal.
6. Maintenance
6.1. Cleaning the Projector Lens
Gently wipe the lens with a soft, lint-free cloth specifically designed for optical surfaces. Do not use abrasive cleaners or excessive force, as this can scratch the lens.
6.2. Lamp Replacement
The projector lamp has a lifespan of up to 10,000 hours. When the lamp life is nearing its end, a warning message may appear, or the lamp indicator LED may illuminate. Refer to the full service manual for detailed lamp replacement instructions. Warning: The lamp contains mercury. Dispose of used lamps according to local environmental regulations.
6.3. Cleaning Air Filters
