Precise racing timer

A racing results display boards 
 1, common anode LED digital tube, seven-segment 6, more clearly than ordinary LED display. 
 2, cable, wireless two-way data transmission, wireless maximum distance up to a ㎞. 
 Issuing the order directly with the company's wireless docking system, issuing the order the automatic timing. 
 Directly with the Company's infrared beam switch docking, cutting the infrared to stop the clock automatically. 
 5, the United States ** IC chip, comes with the clock circuit, the timing accuracy of 100 hours of deviation is less than one second. 
 6, the shell is made of yellow spray, eye-catching and durable, bracket, easy to carry, you can free demolition. 
 7, with the REST button, to prevent data misuse trigger can not be restored. 
 8, the brightness has three adjustments, indoor and outdoor can set the brightness. 
 9 comes with a 4400mA rechargeable battery, the battery can work continuously for 10 hours, convenient outdoor spaces. 
 10, the first line of the A drivers time; The second line shows the B driver time; third line shows all the players, the fastest travel time (real-time refresh the competition results) 
 11, no competition, the third line displays the current time in Beijing 
 Second, the starting point for infrared devices 
 Directly with the company's wireless issuing the order the docking system, the starter automatic timing 
 Directly with the Company's infrared beam switch docking, cutting infrared automatically start the timer 
 3, the reaction time is less than 0.01 seconds 
 4, the shell is made of yellow spray, eye-catching and durable, bracket, easy to carry, you can free demolition 
 5, comes with 4400mA rechargeable battery, the battery can work continuously for 10 hours, convenient outdoor spaces. 
 6, the infrared can be adjusted according to specific game 
 7, when the device power consumption is less than the prompt signal prompt charge. 
 The end of the infrared cut-off signaling equipment 
 Directly with the company's wireless issuing the order the docking system, the starter automatic timing 
 Directly with the Company's infrared beam switch docking, cutting infrared automatically stop the clock 
 3, the reaction time is less than 0.01 seconds 
 4, the shell is made of yellow spray, eye-catching and durable, bracket, easy to carry, you can free demolition 
 5, comes with 4400mA rechargeable battery, the battery can work continuously for 10 hours, convenient outdoor spaces. 
 6, Infrared can be adjusted according to specific game. 
 7, when the device power consumption is less than the prompt signal prompt charge. 
 Note: all equipment, signal transmission are wireless transmission (easy to carry, track layout, signal is stable and reliable), can the docking traffic lights to make the timing, to improve the viewing of racing.
