Can ETC be installed without being placed on the glass top?

ETC can be used without being attached to the glass. Installing ETC on the upper part of the windshield is to minimize obstruction of the driver's view while ensuring better recognition by the equipment at highway toll stations. If you don't want to install it on the glass, try to place it in an open position where it can be seen through the windshield. The general installation position for ETC in small cars is in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is installed 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 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, ETC should be installed in the microwave window strip. Here are some considerations for installing ETC: Do not obstruct the view; it's 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. If ETC is installed without considering this, it can increase the driver's 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 solar panel on the back for self-charging. Therefore, during installation, avoid the blackened 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 presses 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. You would then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. Notes for using ETC: The ETC transaction sensing range is 8 meters. To prevent issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid 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, leading to toll deduction failure. When using a debit card linked to ETC, insufficient balance can also cause toll deduction failure.
