- Liner Ring and Trash Bag Installation:
Place a standard 3-gallon trash bag or NINESTARS custom trash bag (NSTB-3-30) into the trash can base. Secure the trash bag by fitting the removable liner ring over the top edge of the bag and into the can. This holds the bag firmly in place and prevents it from overhanging, ensuring a neat appearance.

- Lid Placement:
Carefully place the motion sensor lid onto the trash can base, ensuring it is securely seated.
Operating Instructions
- Motion Sensor Operation:
To open the lid, simply wave your hand or an object within the sensor's range (approximately 6-10 inches above the sensor). The lid will open automatically. It will remain open for a few seconds and then close softly. The delay sensing technology helps prevent unnecessary opening from pets, children, or casual movement nearby.

- Manual Open/Close:
For extended open time or manual control, press the "OPEN" button on the lid. The lid will stay open until you press the "CLOSE" button. This feature is useful when disposing of larger items or during prolonged use.
Maintenance
- Cleaning:
The stainless steel base is finger-print resistant and easy to clean. Wipe the exterior with a soft, damp cloth and mild detergent. For the motion sensor lid, use a damp cloth only and avoid harsh chemicals or excessive moisture to prevent damage to electronic components.
- Battery Replacement:
When the motion sensor becomes unresponsive or the lid movement slows, it is time to replace the batteries. Follow the battery installation steps in the "Setup" section to replace the 2 C batteries.
