After inputting any one of the specified commands "92221", “92222", or "92223", pressing dial setting button, then press the starting pistol command button to synchronize the timing clock with the starting device. Now, the gun can control the clock. A clock can be used to match the frequency with up to 3 starting pistols, and this clock can be controlled by the all 3 starting pistols.
8. When clock counting or pausing, click "Countdown" button, the clock starts to count down, and will stop after it being "0:00:00"
9. The clock is connected to the UHf readers, read EPC code information of the UHF tags. lt accesses Run8 Cloud by the APP connected with Bluetooth. The clock can display the event results, also can display the corresponding results by inputting bib numbers manually.
10. Input Beijing time of the starting time, click to start timing from then, and the clock displays the duration 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, after wake it up can perform normal operation .
13. Wake the clock up in sleeping state.
14. After the clock in sleeping mode, you can set it to automatically wake up after a certain period of time. lt can be used to wake up clock in deep sleep or normal sleep.
15. Restart the program.
16. Refresh the dial.
17. Test the dial.
18. Countdown to target time.
19. Display 12/24 hour time mode.
20. Synchronize the time on phone with the clock, which is used to synchronize the reference time of multiple clocks.
21. After connecting the data link and app, synchronize or unsynchronize each clock via Bluetooth. Once completed, the data link can simultaneously control multiple clocks within range.
22. Map: Can set 5/6 digit dial, 12/24-hour time.
Ⅲ. Device
1. Side Panel Introduction

Notice
1. Three toggle switches R, G, and B on the top of the side 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 |
↑ | ↓ | ↓ | red |
↓ | ↑ | ↓ | green |
↓ | ↓ | ↑ | blue |
↑ | ↑ | ↓ | yellow |
↑ | ↑ | ↑ | yellow |
↓ | ↓ | ↓ | yellow |
↑ | ↓ | ↑ | purple |
↓ | ↑ | ↑ | cyan |
2. The brightness adjustment knob is used to adjust the clock brightness. The brightness adjustment has 11 levels: 0, 10%, 20%, 100%. Level 0 is set to the minimum brightness, and the brightness increases as the level increases.
Notice
3. The score display terminal only needs to connect with the score sensor board to display the scores.
4. The toggle switch controls whether the front zero displayed. When the toggle is up, the front zero is displayed; when the toggle is down, the front zero is not displayed. In this state, digiboard only displayes the seconds digit and small dot. As the timing progresses, the minutes digit and hours digit are displayed in sequence.
5. The power toggle switch is used to control whether the power display module is working. When the toggle is up, the power is displayed; when the toggle is down, the power is not displayed.
6. The synchronous toggle switch is used to control whether to synchronize with other clocks and must be used in conjunction with another clock by a synchronization cable. The synchronous toggle switch has three states: when the toggle is up, the synchronization function is enabled and requires an external drive signal from other clocks to operate; when the toggle is in the middle, the clock does not operate; when the toggle is down, the clock operates by using its own drive signal.
Notice
7. There are three states for switch locks: on, off, charging. Here, we focus on the charging status. When the key is turned to the switch lock charging position, can use Type-C to charge.
Notice
2. Top Port Introduction

The top port of the clock from left to right: wireless serial port (data link), main charging port, and synchronous cable port.
1. The wireless serial port needs to connect to 170M rubber rod antenna for using. It can receive signals from starting pistol and data link to achieve wireless control functions such as starting or stopping the clock.
2. The main charging port is used with the charger provided by our company.
Notice
3. Synchronous cable port: When the synchronization function of clock 1 is turned on, the driving signal is obtained from clock 2 by using a synchronous cable connection.
