| Why OTA Update Before Use? | To ensure optimal performance and take advantage of our latest features and updates, please upgrade to the most recent software version before first use. You can do this by navigating to Settings > About device > Online upgrade. |
| Is It Good for Daytime Use? | Due to its brightness limitations, the projector is ideal for dark environments, such as a backyard at night, a campsite after sunset, a living room with closed curtains, or a bedroom with the lights turned off. |
| Info on Streaming Services | Due to the HDCP (High-bandwidth Digital Content Protection) agreement, screen mirroring may not function properly (no image or sound) when attempting to mirror content from certain apps, such as Prime Video, Hulu, and others. We recommend that you use a streaming device such as a Fire Stick or Roku. |
| Activate Manual Focus? | If the focus does not produce a clear image, use the 'electronic focus' buttons on the remote control to manually adjust it for optimal clarity. |
| How to Get a Square Image? | Automatic vertical keystone correction works best when the projector lens is directly facing the wall. If the results are unsatisfactory, follow these steps: 1. Place the projector on a flat surface and ensure the lens is perpendicular to the wall. 2. Navigate to Settings > Projection Settings > Keystone Correction > Initial Angle Correction. 3. If needed, disable the automatic keystone correction and make manual adjustments for optimal alignment." |

| Projection Distance? | The distance between the projector and the projection surface must be a minimum of 0.6 m and a maximum of 2.5m. This ensures a projection image between 35" and 135". |
| System upgrade failed? | 1. Confirm whether there is a problem with the backend push. Confirm with the frontend engineering team. 2. Network issue. Try upgrading again, or upgrade after switching to a different network. 3. Simply flash the latest version to resolve the issue. |
| WiFi connected, no internet? | 1. Due to virtual network issues, being connected to WiFi with poor signal may cause this. Try switching to a different network or a phone hotspot. 2. If the app downloads but shows network errors when opened, check if the country and time zone match, and set the time to automatic. 3. If the router supports both 2.4GHz and 5GHz, try connecting the projector to the 2.4GHz network. 4. Perform a factory reset or reflash the device. |
| Fix for black dots on screen | 1. Black spots are unavoidable. Guide the customer through the video cleaning process. 2.
