【Product Function and Structural Features Detailed Introduction】：
The following content may be described in too much detail, which may make you feel dizzy. The main purpose is to help you better understand whether this item is suitable for you to use. In fact, as long as you have the physical item in your hand, you can quickly learn how to use it by roughly looking at the instructions!
★, Four-channel: Four groups of countdown can be used simultaneously or individually for any 1-3 groups.
★, Countdown time: The maximum countdown time for four channels is 99 hours 59 minutes 59 seconds, and the minimum is 1 second; within the time range of 1 second to 99 hours 59 minutes 59 seconds, the countdown time can be set arbitrarily, precise to the second;
★, Sound: After the countdown for each of the four channels ends, there will be different sounds to remind you, with a reminder time of 60 seconds. Here are the sounds for each group:
The first group (T1): "D...D...D...D...
The second group (T2): "DD...DD...DD...DD...
Group 3 (T3): "DDD...DDD...DDD...DDD...
Group 4 (T4): "DDDD...DDDD...DDDD...DDDD...
Remark 1: If you set two or more groups of countdown with end times within 60 seconds of each other, the alarm sequence will be: the group that ends first will sound first. When the second group (or third, fourth, etc.) finishes its countdown, the reminder sound for the first group stops, and the sound for the next group that ends will sound. This continues in a similar manner... Based on the sound characteristics described above, you can tell which group's countdown has just ended by listening to the sound.
Note 2: After the countdown is complete, the display will begin counting up from the end of the countdown. This time is the duration after the countdown ends. As long as you haven't pressed the stop button, it will continue to count up the time after the countdown ends. If you happen to leave when the countdown ends and didn't hear the sound reminder, you can still see how much time has passed since the countdown ended when you return.
★, Countdown: Four channels, in addition to the countdown, can also be used separately or simultaneously for the countdown. The countdown does not have sound reminders, and it cannot set an end time. It cycles from 1 second to 99 hours, 59 minutes, and 59 seconds. When all the numbers on the display are 0, press the start button to enter the countdown.
★, If there are 2, 3, or 4 countdown groups in progress at the same time, the display only shows the time of one group (T1-T4, depending on which button you press last). The group's sequence number (T1, T2, T3, T4) is normally displayed at the top of the screen, and the sequence numbers of the other 2-3 groups that are in progress will blink.
★, when a countdown group ends, in addition to the sound reminder, there will be a blinking small speaker displayed in the upper right corner of the screen (the small speaker disappears 60 seconds after the countdown ends). If your environment is noisy, and you can't hear the sound of the alarm at the end of the countdown, you can also judge whether the countdown has ended based on whether a small speaker appears on the screen. The time on the screen is also blinking;
★, Hour, Minute, Second independent key adjustment, easy to adjust.
★, during the countdown, press the "CLOCK" key to enter the clock state, which does not affect the countdown. Press T1 (or T2, T3, T4), return to the countdown state, and the clock and countdown do not interfere with each other.
★, when the countdown ends, press the "ST/SP" key once to stop the countdown, press the "ST/SP" key again to return to the initial countdown time, and press the "ST/SP" key again to perform the next countdown...
