Setup and Programming
Initial Setup
- Set Current Time: Rotate the clock dial clockwise until the arrow aligns with the current time. The dial is marked with 24 hours (AM/PM).
- Set ON/OFF Times: Push the pins down for the periods you want the connected device to be ON. Each pin represents 15 minutes. If a pin is pushed down, the device will be ON during that 15-minute interval. If a pin is up, the device will be OFF.
- Select Mode: Use the slide switch on the side of the timer to select the operating mode:
- TIMER Mode: The timer will operate according to your set ON/OFF schedule.
- ALWAYS ON Mode: The connected device will remain continuously ON, bypassing the timer settings.
- Plug In: Plug the timer into a standard wall socket. Then, plug your appliance into the timer socket.

Operating the Timer

Manual Override
If you need to temporarily override the timer settings, simply use the slide switch on the side:
- Slide the switch to the ALWAYS ON position to keep the appliance continuously powered.
- Slide the switch back to the TIMER position to resume the programmed schedule.
