Operating Instructions
The Fosmon Outdoor Dual Timer Outlet uses a mechanical dial for setting schedules. The dial represents a 24-hour period, with each segment representing 30 minutes.

- Set Current Time: Rotate the entire dial clockwise until the current time aligns with the arrow indicator (usually a small triangle or line) on the timer's body. The dial has markings for AM and PM (e.g., 12 for noon/midnight, 6 for 6 AM/PM).
- Set ON/OFF Times: The black segments around the dial are pins. Push down the segments corresponding to the times you want the connected devices to be ON. Leave the segments up for the times you want the devices to be OFF. Each segment represents 30 minutes.
- Verify Operation: Once set, the timer will automatically turn your devices ON and OFF according to your programmed schedule. The dial will continuously rotate, indicating the passage of time.
This timer is ideal for automating various outdoor applications, including:
- Outdoor string lights
- Holiday decorations
- Pool pumps
- Engine block heaters
