What is the best location to install ETC?

[VonAndres]

For small cars, the ETC device is generally installed in the upper middle section of the front windshield, while for large vehicles such as trucks and buses, it is installed in the middle to lower section. 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 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, the ETC should be installed in the microwave window area. ETC stands for Electronic Toll Collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is handled 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 needed, and the vehicle must be registered under an individual aged between 18 and 60. Documents required for official vehicles: An introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle registration certificate; The vehicle that needs ETC installation. Here are some precautions for ETC installation: Do not obstruct the driver's view. It is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which reduces the driver's field of vision. Installing the ETC without considering this may increase blind spots. Installing it behind the rearview mirror on the right side 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, as it has a built-in solar panel 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-tamper lever connected to a switch. Once the electronic tag is installed, the windshield will press the anti-tamper 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 mechanism is designed to prevent multiple vehicles from sharing one device.
