The installation position of the car ETC is generally 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. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with built-in explosion-proof film or those that have been retrofitted with explosion-proof film, it will affect the signal transmission of the microwave communication link, so it should be installed in the microwave sunroof strip. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply for it, you need to provide the original and photocopy of the owner's valid ID card and vehicle license. If it is not the owner who applies, the agent's valid ID card is also required. The photocopy of the vehicle license needs to 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 under the name of an individual aged between 18 and 60. Here are the precautions for installing ETC: Do not block 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 blocking 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 because it has 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 that easily blocks the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal guide rod, which is connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed casually, the anti-removal guide rod will pop out and trigger the switch, locking the electronic tag and making it unusable. You will 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 automatically sensing and paying for the vehicle in front. The recognition speed of the ETC lane is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, leading to a failed deduction. When using a debit card to bind ETC, insufficient balance will also cause a failed deduction.
