The visual timer helps in understanding time duration through a colored disk that recedes as time passes.
- Set Time: Rotate the central dial of the visual timer clockwise to set the desired countdown duration (up to 60 minutes). The red disk will expand to indicate the set time.
- Start: The timer begins counting down immediately after setting.
- Completion: When the red disk disappears, the set time has elapsed. An alarm will sound, vibrate, or remain silent based on your selected mode.
