2. Plug the other end of the power adapter into a standard electrical outlet.
3. The power indicator light on the projector will illuminate, indicating it is receiving power.

3. Connecting Devices

The GPX Mini Projector supports various input sources:

• HDMI: Connect an HDMI cable from your device (e.g., laptop, DVD player, game console) to the HDMI In port on the projector. This is the recommended connection for high-definition content.
• VGA: Connect a VGA cable from your computer to the VGA In port.
• USB: Insert a USB flash drive into the USB port to play compatible media files (photos, videos, music).
• AV: Use the included 3.5mm to RCA AV cable to connect older devices with RCA outputs (yellow for video, red/white for audio) to the AV In port.

4. Focus and Keystone Adjustment

• Focus: Rotate the Focus Adjustment Dial (refer to Figure 2) until the projected image appears sharp and clear.
• Keystone: If the projected image appears trapezoidal (wider at the top or bottom), rotate the Keystone Correction Dial (refer to Figure 2) to square the image.

Maintenance

1. Cleaning

• Lens: Use a soft, lint-free cloth specifically designed for optical lenses. Do not use abrasive cleaners or cloths that could scratch the lens.
• Exterior: Wipe the projector's casing with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, but ensure no liquid enters the device.
• Ventilation Openings: Periodically check and gently clean the ventilation grilles to prevent dust buildup, which can impede airflow and cause overheating. Use a soft brush or compressed air.

2. LED Bulb Life

The GPX Mini Projector uses an LED light source with an estimated life of 20,000 hours. This means the bulb is designed to last for the lifetime of the product under normal usage and does not require replacement.

3. Storage

When not in use for extended periods, store the projector in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to keep it in its original packaging or a protective case to prevent dust accumulation and physical damage.
