The timer works on the principle of winding: you must wind it once before using it to set the time.

If you want to set a specific operation for 5 minutes, please follow the steps below:

Step 1: Turn clockwise to 55 degrees (55 minutes).

Step 2: Rotate counterclockwise to return to the time you want to set, such as 5 minutes.

Step 3: You will hear a dripping sound, and after 5 minutes, the alarm will go off.

If you want to set other times, the operation method is the same. Remember to wind the spring after each use. You need to operate this method once. It's convenient to use it easily!
