Where to Place the ETC on the Car Windshield?
1 Answers
The installation position for small vehicle ETC is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it 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 microwave communication signal transmission, the ETC should be installed in the microwave sunroof strip. Here are the precautions 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 this is not considered during ETC installation, 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 black 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. Once the electronic tag is installed on the windshield, the anti-removal lever is pressed 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. 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, 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, leading to payment failure. When using a debit card linked to ETC, insufficient balance can also cause payment failure.
