Operating Instructions
Motion Sensor Operation
- Ensure the power switch (located on the back of the lid) is in the 'ON' position.
- To open the lid, simply wave your hand or an object within 5.9 inches (15 cm) above the sensor area.
- The lid will open automatically and remain open for approximately 4-7 seconds.
- After the delay, the lid will close automatically. If an object remains in the sensor's detection area, the lid will stay open until the object is removed.

Maintenance
Care and Cleaning
- To clean the exterior, wipe with a soft, damp cloth and mild detergent. Avoid abrasive cleaners or scrubbers that could damage the stainless steel finish.
- The anti-fingerprint design helps reduce smudges, but regular wiping will maintain its appearance.
- For the interior, remove the inner liner and wash it with soap and water. Ensure it is completely dry before placing it back into the trash can.
- Do not immerse the sensor lid in water, as this can damage the electronic components.
Battery Replacement
When the sensor's response becomes slow or the lid stops opening, it is time to replace the batteries. Replace all 4 C-size batteries simultaneously for optimal performance.
