Can ETC be installed without mounting it on the windshield?

[DiJoanna]

ETC can be used without being stuck to the windshield. Installing ETC on the upper part of the windshield is to minimize obstruction of the driver's view and to ensure better recognition by the equipment at highway toll stations. If you don't want to install it on the windshield, try to place it in an open position where it can be seen through the windshield. For small cars, the ETC installation position is generally in the upper middle part of the front windshield, while for large vehicles like trucks and buses, the installation position is 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 the signal transmission of the microwave communication link, the ETC should be installed in the microwave window strip. Here are the precautions for installing ETC: Do not block the view; it's best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt, 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 because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the blackened areas on the windshield and 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 the electronic tag is installed, 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. You will then need to visit an ETC service point to unlock it. This 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 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 payment for the preceding 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 failed deductions. When using a debit card linked to ETC, insufficient balance may also cause deduction failures.
