4. Operation
4.1 Powering On/Off
The monitor automatically powers on when connected to a compatible device via USB-C and receives a video signal. To power off, disconnect the USB-C cable from the source device.
4.2 Adjusting Display Settings (OSD Menu)

5. Maintenance
5.1 Cleaning the Screen
To clean the monitor screen, gently wipe it with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a mild, non-abrasive screen cleaner. Avoid using harsh chemicals, alcohol, or ammonia-based cleaners, as these can damage the screen surface.
5.2 Storage
When not in use, store the ZenScreen MB166C in its protective sleeve to prevent scratches and dust accumulation. Store it in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
6.1 No Display/No Signal
- Ensure the USB-C cable is securely connected to both the monitor and the source device.

- Check the display settings on your source device to ensure it is configured to output to an external monitor.
