1. The method of using the stopwatch function:
1. In the clock interface, the second and third rows are the stopwatch display screen, the second row shows 0.** seconds, and the third row shows hours, minutes, and seconds.
2. Press the START/STOP button to start the normal counting, and then press the START/STOP button to pause, and then press the START/STOP button to continue the normal counting; after the normal counting is completed or paused, press the CLEAR button to reset the normal counting time, and the CLEAR button will not work when the normal counting is in progress.
3. During the normal countdown process, you can press the CLOCK/TIMER key to enter the countdown interface for operation. You can use the countdown function; in the normal countdown (stopwatch) interface, you can see the status of the channels that are currently running and have completed the countdown.

II. How to Use the Countdown Function:
1. Press the CLOCK/TIMER button to switch to the countdown interface.
2. If only a group of countdown is needed, press the T1 key (or the T2, T3 keys, the same below) for two seconds, and the first row of "0:00:00" will blink. Press the HR, MIN, SEC keys to set the time, minutes, and seconds, respectively. Press the T1 key to confirm, and then press the T1 key again to start the countdown for this channel. Press the T1 key again to pause (you cannot press the CLEAR key while in the paused state, or the countdown time will be cleared). After the countdown is complete, the channel will blink and start counting down the time again. A sound reminder will be given for one minute. Press the T1 key to stop the alarm sound and the normal countdown. At this time, the screen will display the time after the countdown is complete and will blink. Press the CLEAR key to return the channel to the initial state of 0:00:00. If you need to repeat the countdown, press the T1 key once to display the pre-set countdown time, and then press the T1 key again to start the countdown again.......
3. If you need to start two or three groups of countdown simultaneously, set the countdown times for channels T1, T2, and T3 as described above. Press the START/STOP button to start the countdown for each channel simultaneously. After each channel's countdown is complete, the time will be displayed. When the countdown stops, press the CLEAR button to reset each channel. Then, press the START/STOP button to re-enter the countdown times for each channel. Press the channel buttons (T1, T2, T3) to start the countdown for that channel separately.
4. If you need to perform a 2 or 3-group countdown with different start times, you can set them separately after setting them, and operate each channel separately by pressing the corresponding channel key. Each channel will not affect each other.
