Can ETC be attached to the black area of the windshield?
1 Answers
The ETC device can be installed on the black dotted area of the windshield, as long as it does not obstruct the driver's view and can detect the toll station's sensing equipment. However, installing it on the black dotted area of the windshield also has drawbacks, such as reduced solar charging capability of the ETC device, which may lead to power depletion over time. 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 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. If the vehicle has a factory-installed or aftermarket anti-explosion film, it may affect the signal transmission of the microwave communication link, and the ETC should be installed in the microwave window area. Here are some considerations for ETC installation: 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 can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not affect 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 black areas of the windshield and positions where the solar panel might be easily obstructed. 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 will press the anti-removal lever in. If the device 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. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by the preceding vehicle's ETC device malfunction, maintain a distance of at least 10 meters from the preceding vehicle to prevent automatic sensing and paying for the preceding vehicle's toll. 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 cause toll deduction failure. When using a debit card linked to ETC, insufficient balance may also lead to toll deduction failure.
