CAIWEI, established by Guangzhou Caiwei Optoelectronics Co., Ltd. (also known as Guangzhou Caiwei Electronic Technology), is a manufacturer specializing in projection technology since 2003. The brand produces a wide range of video projectors designed for home cinema, outdoor entertainment, and business presentations.

• How do I connect my CAIWEI projector to Wi-Fi?

  Navigate to the 'Settings' menu on the projector interface, select 'Network' or 'Wi-Fi', switch it on, and choose your wireless network from the list. Enter the password to complete the connection.

• How do I clean the air filter on my projector?

  Lightly press the bottom of the air inlet to pop out the filter. Use a soft brush to gently sweep away dust. Do not wash the filter with water as it may damage the material.

• Why can I not screen mirror Netflix or Disney+ content?

  Copyright-protected content from apps like Netflix, Prime Video, and Hulu often cannot be mirrored or cast wirelessly due to HDCP restrictions. You may need to use a TV stick (e.g., Fire Stick, Roku) connected via HDMI or the built-in apps if your projector has an Android system.

• How do I adjust the image if it is blurry or trapezoidal?

  Use the manual focus wheel or remote focus keys to sharpen the image. For trapezoidal distortion, use the Keystone correction settings (automatic or 4-point manual) in the Projection Settings menu to square the image.

• How do I pair a Bluetooth audio device?

  Go to 'Settings' > 'Bluetooth', turn on the Bluetooth switch, select 'Management' or 'Search', and choose your Bluetooth speaker or headphones from the list to pair.
