Maintenance
1. Cleaning
- Use a soft, dry cloth to clean the projector's exterior.
- For the lens, use a lens cleaning cloth and solution specifically designed for optical surfaces. Avoid abrasive cleaners or harsh chemicals.
- Regularly check and clean the ventilation openings to prevent dust buildup, which can affect performance and lifespan.
2. Storage
- Store the projector in a cool, dry place away from direct sunlight and extreme temperatures.
- If storing for extended periods, ensure the built-in battery is partially charged (around 50%) to prolong its lifespan.
Troubleshooting
1. No Image / Poor Image Quality
- Check Focus: Adjust the focus wheel on the side of the projector.
- Input Source: Ensure the correct input source (HDMI, USB, Wireless Display) is selected.
- Cable Connections: Verify all HDMI or USB cables are securely connected.
- Wireless Display: For screen mirroring, confirm both the projector and your device are on the same Wi-Fi network.
- Image Graininess: If the image appears grainy, try projecting onto a different, smoother surface or a dedicated projector screen.
2. Battery Life Shorter Than Expected
- Battery life is typically 1.5-2.5 hours, depending on usage and brightness settings. Higher brightness consumes more power.
- For extended viewing, connect the projector to the power adapter or a compatible power bank (>DC 5V 3A).
3. Cannot Connect to Laptop Wirelessly
- Ensure your laptop supports Airplay/Miracast/DLNA protocols or that you have the Eshare app installed.
- Verify that both your laptop and the projector are connected to the same Wi-Fi network.
4. Netflix/Streaming App Issues
- Ensure you have a stable and strong internet connection.
- Try updating the streaming application to its latest version.
- Some apps may have regional restrictions or specific compatibility requirements.
5. No Sound / Poor Sound
- Check the projector's volume settings.
- If using external speakers, ensure they are properly connected to the 3.5mm audio out port or correctly paired via Bluetooth.
6. Overheating / Fan Noise
- Ensure that the projector's ventilation vents are not blocked.
- In the Android OS settings, there may be an option to adjust the fan speed for cooling during prolonged or heavy use.
7. USB Drive Not Recognized
- Ensure the USB drive is properly inserted into the USB 3.0 port.
- Verify that the file system of the USB drive is compatible (e.g., FAT32, NTFS).
- Try using a different USB drive to rule out drive issues.
User Tips
- For optimal viewing, especially during the day, use the projector in a darkened room or at night.
- When connecting to a power bank, ensure it provides >DC 5V 3A output for proper charging and operation.
- The built-in speakers are quite good for a portable device, but for a truly immersive audio experience, consider connecting external Bluetooth speakers.
- If you experience any lag with streaming apps like Netflix, ensure your internet connection is strong and stable.
