6. Operating Instructions

Use the remote control to navigate the projector's on-screen interface. The remote allows you to select input sources, adjust settings, and control media playback.
6.2 Connecting Devices
The HY300 mini projector offers various connectivity options:
- HDMI: Connect your laptop, TV stick, or gaming console using an HDMI cable. Select the HDMI input source from the projector's menu.
- USB: Insert a USB flash drive into the USB port to access photos, videos, or documents.
- Wi-Fi Screen Mirroring: Connect the projector to your Wi-Fi network. Use the screen mirroring function (e.g., Miracast for Android, AirPlay for iOS) on your mobile device to project its screen wirelessly.
- Bluetooth: The product is advertised with Bluetooth connectivity for audio output. However, some user reports indicate this feature may not function as expected. If you intend to use external Bluetooth speakers, you may need to connect them directly to your source device (e.g., phone, laptop) if the projector's Bluetooth is unreliable.
- Audio Out: Connect external speakers or headphones via the 3.5mm audio jack for enhanced sound.
6.3 Optimizing Projection Quality
For the best viewing experience, ensure the room is dark. The projector supports 1080P input, with a native resolution of 1024x720. While it can display 1080P content, the actual clarity will be limited by its native resolution.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No image or dim image | Insufficient power supply; room too bright. | Ensure a high-power charger (e.g., 30W) is used. Operate in a dark room. |
| Image flickering or turning blue | Unstable power; internal malfunction. | Verify power connection and charger wattage. If problem persists, contact support. |
| Remote control not working | Batteries low/dead; sensor obstructed/misaligned. | Replace batteries. Ensure remote is pointed directly at the projector's IR sensor, possibly at close range. |
