For passenger cars, the ETC device is generally installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the lower middle part. The appropriate installation position should be at a height of no less than 1.2 meters and no more than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the device should be installed in the microwave skylight strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also required, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which reduces the driver's field of vision. If this is not considered when installing ETC, it will increase the driver's blind spot. Install it behind the right side of the rearview mirror to avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not need to be charged or have its battery replaced, as there is a solar panel on the back that can charge itself. Therefore, when installing, avoid the black areas on the windshield and do not install it in a position where the solar panel is easily blocked. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal guide rod, connected to a switch underneath. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed arbitrarily, the anti-removal guide rod will pop out and trigger the switch, locking the electronic tag and making it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note that: the ETC transaction sensing area is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, keep a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The speed limit for ETC lane recognition is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, leading to failed toll deduction. When using a debit card to bind ETC, insufficient balance will also cause toll deduction to fail.
