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 the clock. The command gun after the frequency is used to control the clock clock with the frequency. A clock can be used to match the frequency with up to 3 starters. The clock can be controlled by the 3 starters with good frequency. Enter the specified command"93333" to delete all command guns that are over frequency with the clock.
8. When the clock is timing or pausing, pressing the Countdown button, and the clock starts to countdown, and stops after the countdown is"0:00:00".
9. Clock score display function: The clock is connected to the UHF chips card readers, reading the EPC code information of the UHF electronic tags, and accessing the Run8 Cloud backend through the mobile APP connected by Bluetooth. The clock can display the completion results corresponding to the UHF tags. You can also display the corresponding scores of this tag by manually entering the competition number.
10. Equivalent start time: Enter the Beijing time of the start time, click to start the positive timing from that time, and the clock displays the game duration from the start time.
11. Sleep clock: Make the clock enter low-power mode, and can only perform normal operation after wake-up.
12. Deep sleep: Turn off the clock network while entering low-power mode, and only normal operation can be performed after wake-up.
13. Wake up clock: Wake up the clock in sleep state.
14. Appointment wake-up: After the clock slept, you can make a reservation for a certain period of time and let the clock automatically wake up. It can be used to wake up the clock in deep sleep or normal sleep modes.
15. Clock restart: Restart the main clock program.
16. Refresh the dial: Push all digital chips of the clock once.
17. Test the dial: Test all digital displays(0-9) to check whether the digital chips are normal.
18. Countdown to the target time: Select a certain moment after the current moment, and the clock countdown to zero when it reaching that moment, or starting regular timing.
19. Display 12/ 24 hour time: Used to switch clock time display mode.
20. Timing settings: Used to time the mobile phone to give the clock at the moment, and is often used to unify the reference time of multiple clocks.
Ⅲ. Device
1. Side Panel Introduction

Notice
1. Three rocker switchesR, 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 0
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 brightness of the clock, and the brightness adjustment is divided into 11 stops 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 be connected to the score sensing board to achieve the score displayed.
4. The front zero display rocker switch controls whether the front zero is displayed or not. The rocker arm up indicates the front zero displayed, and the rocker arm down indicates the front zero didn't display. In this state, the digital board only has the second and small dots. As the timing carrying, the minute and time positions will lit up one after another. The purpose of this design is to save power.
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.
1. The wireless serial port needs used with 170M glue rod antenna, which can receive control signals from our gun type generators and data links related products to realize wireless controlling functions such as starting or stopping timing.
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.
