Input Source Selection

Press the "Input" or "Source" button on the projector or remote control to cycle through available input sources (HDMI, VGA, Composite, S-Video, etc.) until your desired source is displayed.

Image Adjustment

Focus: Rotate the focus ring on the projector lens until the image is sharp and clear.
Zoom: Adjust the zoom ring on the projector lens to change the image size without moving the projector.

Color Correction: Access the projector's on-screen display (OSD) menu to adjust color settings, brightness, and contrast for optimal image quality.

Audio Output

The projector has built-in speakers. For external audio, connect speakers or headphones to the Headphone Jack or use the audio output from your source device.

Maintenance

Lamp Replacement

When the "LAMP REPLACE" indicator illuminates, it is time to replace the projector lamp. Refer to the specific lamp replacement instructions provided with your replacement lamp or consult a qualified technician. Always allow the projector to cool down completely before attempting lamp replacement.

Air Filter Cleaning

Regularly clean the air filter to maintain optimal performance and prevent overheating. While this specific unit is noted as having "No Filter Cover", general projector maintenance often involves cleaning air intake areas. Use a soft brush or vacuum cleaner to remove dust from the ventilation grilles.
