Maintenance
Regular maintenance will ensure the longevity and optimal performance of your medicine cabinet.
- Cleaning the Mirror: Use a soft, lint-free cloth and a non-abrasive glass cleaner. Spray the cleaner onto the cloth, not directly onto the mirror, to prevent liquid from seeping into the edges.
- Cleaning the Cabinet: Wipe the cabinet surfaces with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the finish.
- Electrical Components: Ensure the power is off before cleaning any electrical parts. Do not spray water directly onto the light components.
- Hinges: Periodically check the hinges for tightness and smooth operation. Tighten screws if necessary.

If you encounter any issues with your medicine cabinet, refer to the following common problems and solutions:
- Lights Not Turning On:
- Check if the power supply is connected correctly and the outlet is functional.
- Ensure the main power switch (if hardwired) is on.

- Lights Flickering or Dim:
- Verify the power connection is stable.
- Adjust the brightness using the stepless dimming function.
- Door Not Closing Properly:
