Can ETC be used without sticking to the windshield?

[SanEllie]

ETC can be used without sticking it 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 highway toll station equipment. 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. For large vehicles like 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 factory-installed or aftermarket explosion-proof film, which may affect microwave signal transmission, ETC should be installed in the microwave window area. Here are some precautions for ETC installation: Do not obstruct the view; it's best to install it behind the rearview mirror: Many car models have a steeply inclined windshield, which can reduce the driver's field of vision. Installing ETC without considering this can increase blind spots for the driver. 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 in positions where the solar panel might be blocked. Do not remove it arbitrarily once installed: The adhesive pad in the middle has an anti-removal rod connected to a switch. After installation, the windshield presses the anti-removal rod in. If the tag is removed arbitrarily, the rod 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. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of at least 10 meters from the vehicle ahead to prevent automatic payment for the wrong vehicle. The ETC lane recognition speed is 20 km/h; driving too fast may result in failure to read the vehicle's device information and cause payment failure. If using a debit card linked to ETC, insufficient balance may also lead to payment failure.
