The ETC installation position 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 suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with built-in or later-added explosion-proof film, which may affect the signal transmission of the microwave communication link, it should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopy of the vehicle owner's valid ID and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID 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 needed, and the vehicle must be registered under an individual aged between 18 and 60. For company vehicles, the required documents are: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the original ID of the agent; the original vehicle registration certificate; and the vehicle that needs to apply for ETC. 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 rearward tilt angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spot. Installing it behind the rearview mirror on the right side can 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, as there is a solar panel on its back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not place it where the solar panel might be blocked. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal lever, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed casually, the lever will pop out and trigger the switch, locking the electronic tag and rendering 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.
