4.4 Keystone Correction
The projector features innovative 4D keystone correction, allowing for adjustment along both vertical and horizontal axes. Use the remote control to correct the image distortion by up to ±50° along the four sides of the image and ±40° for the entire image.
4.5 X/Y Zoom Function
The X/Y Zoom function allows you to adjust the image size without moving the projector, which is particularly useful for ceiling-mounted installations. You can zoom the image horizontally from 50% to 100% and vertically from 50% to 100% using the remote control.
4.6 External Audio Output
To use external speakers with the projector:
- Via Audio Cable: Connect an audio cable from your external speaker to the projector's audio output port. Then, navigate to the Android home page, go to "Settings," then "Projector," and set the sound output to "line out."
- Via Bluetooth: If your external speaker supports Bluetooth, you can pair it directly with the projector's Bluetooth. This eliminates the need for an audio cable.
5. Maintenance
5.1 Cleaning the Lens
Gently wipe the projector lens with a soft, lint-free cloth specifically designed for optical surfaces. Avoid using abrasive cleaners or excessive force, as this can scratch the lens.
5.2 Cleaning the Casing
Use a soft, dry cloth to clean the projector's casing. For stubborn dirt, slightly dampen the cloth with water and then wipe dry immediately. Do not use chemical solvents.
5.3 Lamp Life
The projector utilizes an LED lamp with an estimated lifespan of 100,000 hours. Regular cleaning and proper ventilation can help maintain optimal lamp performance.
6. Troubleshooting

- Check the connection cable between the projector and the source device.
6.2 Poor Image Quality
- Adjust the focus ring on the projector lens until the image is clear.
- Use the keystone correction function to square the image if it appears trapezoidal.
