- For wireless connections, ensure the projector and your device are within 1 meter for stable WiFi.
- Copyrighted Content: Due to copyright protection, streaming apps like Amazon Prime Video, Hulu, and Netflix do not support screen mirroring. For these services, use a PC or a TV Stick (e.g., Fire TV Stick) connected via HDMI.
5.2 No Sound Output
- If connecting a Toshiba REGZA series recorder and experiencing no sound, try connecting via AV (RCA) cable directly.

- Ensure two new AAA batteries are correctly installed in the remote control.

5.5 General Connection Notes
- When connecting multiple external devices, the projector can only read one signal source at a time. If one HDMI port is used for input, another HDMI port might only function as a power supply.
- For HDMI connection with iOS devices, use an authentic Apple Lightning to Digital AV adapter. For Android, use an authentic Type-C conversion cable.
