How to Check if ETC is Usable?

[ElenaRose]

Methods to check if ETC is functioning properly: Manually insert and remove the card; if there is a sound, it indicates that the ETC is in normal working condition. How ETC works: Through the on-board electronic tag installed on the vehicle's windshield and dedicated short-range communication with the microwave antenna in the ETC lane at the toll station, the computer network technology is used to perform background settlement processing with the bank, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping while paying the toll. Where ETC can be installed: For small vehicles such as cars and vans, the OBU device is installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, the installation position is in the lower middle part. ETC installation position requirements: The height should not be less than 1.2 meters or more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane).
