12bet sports betting

This manual is prepared in accordance with the provisions of GB/T 9969-2008 Industrial Product Instructions for Use General Provisions。 1. Overview ZDL12矿用12bet sports betting （以下简称12bet sports betting ）是一种，Containing gas or coal dust、Places where explosive gases etc. exist，运行的各种机动车辆配套使用的12bet sports betting 。该12bet sports betting 输入12V DC（本安）电压，There are 4 probes，Can emit ultrasonic waves，Detect the situation within 2 meters around the rear of the vehicle，Send voice alarm when encountering obstacles，And display the distance to the obstacle on the paired display，Help drivers and passengers to prevent in time，Ensure the safety of vehicles and drivers and passengers。 2. Working principle 12bet sports betting 可以输入一个12V本安电，4 probes can emit ultrasonic waves，Detect surrounding environment，The distance between the vehicle and obstacles can be displayed on the display，And issue a voice alarm。Remind drivers and passengers to pay attention to safety。 3Model naming and classification 3.1 model naming: Z DL 12 Operating voltage Reversing radar Device 3.2 Explosion-proof type and marking: 见12bet sports betting 中各设备的防爆型式。 3.3Reversing radarDevice的组成 See Appendix A and Appendix B. 4.Environmental conditions 4.2.1Reversing radarDevice应at下列环境条件下正常工作： a.
