- Ensure the timer is clean and dry before plugging it into a wall socket.
3.2 Setting the Current Time
- Rotate the entire dial clockwise until the current time aligns with the arrow marker on the top of the timer. The dial is marked with hours (0-24) and days of the week (I-VII).

3.3 Programming the Timer
The timer features 84 blue switching segments around the dial. Each segment represents a specific time interval (2 hours). Pushing a segment inwards activates the connected appliance during that interval, while pulling it outwards deactivates it.
- Identify the desired ON and OFF times for your appliance.
- For each period you want the appliance to be ON, push the corresponding blue segments inwards.
- For each period you want the appliance to be OFF, ensure the corresponding blue segments are pulled outwards.
- The weekly program allows for different settings across the days, indicated by Roman numerals (I-VII) on the inner ring.
