Setup
1. Placement
Place the projector on a stable, flat surface. Ensure there is adequate ventilation around the unit, keeping at least 30 cm (12 inches) clear space from walls or other objects to prevent overheating. Avoid direct sunlight or strong light sources that may affect projection quality.
2. Power Connection
- Connect the provided power adapter to the DC 12V input port on the projector (refer to Figure 2).
- Plug the power adapter into a suitable electrical outlet.
3. Initial Power On
- Press the Power button on the projector or the remote control to turn on the device.
- Allow a few moments for the projector to boot up.
4. Focus and Keystone Adjustment
Adjust the focus ring near the lens until the projected image is clear. If the image appears trapezoidal, use the keystone correction feature (usually found in the projector's settings menu) to square the image.
Operating Instructions
1. Connecting Devices
- HDMI: Connect your game console, set-top box, or computer to the HDMI port (refer to Figure 3). Select the HDMI input source from the projector's menu.
- USB: Insert a USB flash drive into the USB port to play media files directly. You can also connect a USB keyboard or mouse for easier navigation (refer to Figure 3).
- Wi-Fi: Navigate to the network settings in the projector's menu to connect to a wireless network. This enables smart features and streaming.
2. Navigation and Settings
Use the remote control or the physical buttons on the projector to navigate through the on-screen menu. Adjust settings such as picture mode, sound mode, input source, and network configuration as needed.
3. Playing Media and 3D Content
Once a source is selected, the projector will display the content. For 3D content, ensure your source material is 3D compatible and use appropriate 3D glasses (sold separately) for an immersive experience.
Maintenance
- Lens Cleaning: Gently wipe the projector lens with a soft, lint-free cloth specifically designed for optical surfaces. Do not use abrasive cleaners.
- Air Vent Cleaning: Regularly check and clean the air vents to ensure proper airflow and prevent overheating. Use a soft brush or compressed air to remove dust. Important: Do not block the air outlet during operation.
