This diagram illustrates how the light resumes its last settings after a power cut, with a note about the 4-hour delay for the light to turn on if the programmed ON time is after 12 PM.

6. Maintenance

Cleaning: Regularly wipe the light fixture with a soft, damp cloth to remove dust and water spots. Ensure the light is unplugged before cleaning. Do not use abrasive cleaners or solvents.
Inspection: Periodically check the power cord and adapter for any signs of damage, such as fraying or cracks. If damage is found, discontinue use and replace the component immediately.
Water Resistance: The light has a water-resistant coating, but it is not submersible. Avoid direct immersion in water and ensure the control panel remains dry.

7. Troubleshooting

Table 2: Troubleshooting Guide
Problem	Possible Cause	Solution
Light does not turn on.	No power supply. Power adapter or light fixture is faulty.	Check power connection to the outlet and the light. Ensure the outlet is working. If possible, test with another compatible adapter. If still not working, the light or adapter may be faulty.
