5. Setup
5.1 Projector Placement
Position the projector on a stable, flat surface or mount it securely. Ensure the projector is perpendicular to the screen for optimal image geometry. Maintain a clear space of at least 30 cm (12 inches) around the ventilation openings.
5.2 Connecting Devices
Connect your source device (e.g., laptop, gaming console, DVD player) to the projector using the appropriate cable.
- HDMI: For high-definition digital video and audio. Connect an HDMI cable from your source device to the HDMI port on the projector.
- VGA: For analog computer signals. Connect a VGA cable from your computer's VGA output to the VGA port on the projector.
- S-Video: For standard definition video. Connect an S-Video cable from your source device to the S-Video port.
- Audio In: If using VGA or S-Video, connect an audio cable from your source device's audio output to the Audio In port on the projector.
5.3 Powering On/Off
- To Power On: Connect the power cord to the projector and a power outlet. Press the POWER button on the projector's control panel or remote control. The power indicator light will turn green.
- To Power Off: Press the POWER button twice. The projector will enter a cooling cycle, and the power indicator will flash. Do not unplug the projector during the cooling cycle. Once the light stops flashing, it is safe to unplug.
6. Operating Instructions
6.1 Input Selection
After powering on, the projector will automatically detect an active input. If multiple sources are connected, press the INPUT button on the control panel or remote control to cycle through available input sources (HDMI, VGA, S-Video).
6.2 Image Adjustment
- Focus: Rotate the focus ring on the lens until the image appears sharp and clear.

- Lens: Gently wipe the lens with a soft, lint-free lens cleaning cloth. Avoid using abrasive cleaners.
- Air Filter: The air filter should be cleaned regularly (e.g., every 100 hours of use) to maintain optimal performance and prevent overheating. Refer to the projector's specific instructions for filter removal and cleaning.
