The ETC installation position is generally on the upper middle part of the front windshield horizontally, while for large vehicles like trucks and buses, it is installed on 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 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, meaning electronic toll collection system. To apply, the vehicle owner needs to provide their valid ID card and the original and photocopy of the vehicle registration certificate. If the application is processed by a non-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 needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; the vehicle for which ETC is to be installed. Here are some precautions for ETC installation: 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 ETC installation does not consider this, it may increase the driver's blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, avoid installing it on the blackened areas of the windshield or positions that may block the solar panel. Do not remove it arbitrarily once installed: 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 removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device.
