5. Setup

- If cleaning small items like jewelry or watches, place them in the cleaning basket or use the watch stand provided. This prevents items from resting directly on the tank bottom, which can reduce cleaning efficiency and potentially damage delicate items.
- Carefully place the basket or watch stand with items into the water-filled tank.
- Close the lid.
- Plug the power cord into a suitable electrical outlet.
6. Operating Instructions

- Add Detergent (Optional): For stubborn stains, a small amount of non-abrasive cleaning solution or detergent can be added to the water for enhanced cleaning. Refer to the detergent manufacturer's instructions for dilution.
- Automatic Shut-off: The cleaner will automatically turn off once the selected cleaning cycle is complete.
