The installation position of ETC for small cars is generally 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 suitable 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 factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic Toll Collection. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle license. If the application is made by a proxy, the proxy's valid ID card is also required. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed, 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 steeply inclined windshield, which can reduce the driver's field of vision. If ETC is installed without considering this, it may increase the driver's blind spots. Installing it behind the right side of the rearview mirror can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by a malfunctioning ETC device in the vehicle ahead, maintain a distance of more than 10 meters from the preceding vehicle to prevent automatic toll deduction for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and unsuccessful toll deduction. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.
