2. To preset the time, press the "score adjustment button" and the screen will display the score increasing from zero. If you reach the preset time you need, you can release the "score adjustment button" (or tap the preset button) and use the same method to preset the number of seconds. If the preset time exceeds the set time you need, you can operate the reset button, clear it, and reset it.

An alarm will sound 8 seconds before the countdown ends, and the alarm will stop when the count ends. During the timing process, if you want to stop the timing, you can press the "Pause" button.
4. Rotate the dimming knob to adjust the brightness of the darkroom red light, LED light source, stable and reliable.
