4. Click "Add One Second" button, clock plate will add 1 second.
5. Click "Reduce One Second" button, clock plate will reduce 1 second.
6. Click "Equivalent Start Time" button, setting gun time, the clock will start timing from then.
7. Enter number that conforms to the time logic inside the dial box, and press the Set Dial button todisplay the time information what you set. Enter any of the specified commands "92221", "92222'and "92223", and then click the set dial, and then press the command button of the starter and theclock. The command gun after the frequency is used to control the clock clock with the frequency. Aclock can be used to match the freguency with up to 3 starters. The clock can be controlled by the 3starters with good frequency. Enter the specified command "93333" to delete all command qunsthat are over frequency with the clock.
8. When clock timing or pausing, click "Countdown" button, the clock start count down, and stopsafter it becoming "0:00:00".
9. The clock is connected to the UHF chip readers, reading EPC code information of the UHFelectronic tags, and accessing Run8 Cloud backend through the mobile APP connected by Bluetooth. The clock can display the completion results corresponding to the UHf tags. You can alsodisplay the corresponding scores of this tag by entering the competition number manually.
10. Enter Beiljing time of the start time, click to start timing from then, and the clock displays theduration from start time.
11. Make the clock enter low-power mode, and can only perform normal operation after wake up.
12. Turn off the clock network while entering low-power mode, and can only perform normaoperation after wake up.
13. Wake up the clock in sleeping state.
14. You can make a reservation for a certain period of time and let the clock wake up automaticallyIt can be used to wake up clock in deep sleep or normal sleep.
15. Restart the main program.
16. Refresh the dial.
17. Test the dial.
18. Select a certain moment after the current moment, and the clock countdown to zero when itreaching that moment, or start timing.
19. Display 12/24 hour time.
20. Used to set the time of Beljing time at this moment to the clock, and is often used to unify thereference time of multiple clocks.
21. After connecting the data link and the mobile APP, the frequency pairing or canceling thefrequency pairing through Bluetooth and the clock is connected one to one, The data link after thefrequency matching can control the frequency matching clock, and the data link without thefrequency matching cannot control the clock. The data link with the clock frequency can controlmultiple clocks within the range at the same time. The control range is wide, the connection is morestable, and the common term starts the clock at the beginning and end of large events.
22. Click Global Setting in the upper left corner of the map interface, can set the 5/6-digit dial andthe 12/24-hour time.
Ⅲ. Device
1. Side Panel Introduction

Notice
1. Three rocker switches R, G, and B on the top of the side control panel control the clock color, and there are 6 colors to adjust: red, green, blue, yellow, purple and cyan.
Rocker switch R | Rocker switch G | Rocker switch B | Color |
up | down | down | red |
down | up | down | green |
down | down | up | blue |
up | up | down | yellow |
up | up | up | yellow |
down | down | down | yellow |
up | down | up | purple |
down | up | up | cyan |
2. The brightness adjustment knob realizes the adjustment of the clock brightness, and the brightness adjustment is divided into 11 gears. 0, 10%, 20%, 100%. The 0 gear is set to the minimum brightness, and the brightness of other gears increases as the value increases.
Notice
3. The score display terminal needs to connect to the score sensing board to achieve score displayed.
5. The power display rocker arm switch is used to control whether the power display module is working. The rocker arm displays the power upward, and the rocker arm closes the power display downward.
6. The synchronous rocker switch is used to control whether other clock signals are synchronized, and it needs to be used with another clock through a synchronization line. There are three states for synchronous rocker switches: the rocker arm is facing up and the synchronization function needs to be activated, and the driving signals of other clocks need to be connected to the driving signals of other clocks to work; the center of the rocker arm is turned off. The clock in this state does not work; the clock in the clock down is working with its own driving signals.
Notice
7. There are three states for switch locks: on, off, charging. Here, we focus on the charging status. When the key twists to the switch lock charging position, you can use the typeC charger to charge the clock.
Notice
2. Top Interface Introduction

The top interface of the clock is from left to right: wireless serial port(data link), main charging port, and synchronization line interface.
2. The main charging port is used with the charger provided by our company.
Notice
3. Synchronous line interface: When the synchronization function of clock 1 is turned on, the driving signal is obtained from clock 2 by using a synchronization line connection.
