Can ETC be attached to the black dot area of the glass?

[LeSawyer]

The ETC device can be installed on the black dot area of the windshield, as long as it does not obstruct the driver's view and can detect the toll station's detection equipment. However, installing it on the black dot 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 appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 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 sunroof strip. Here are the precautions for ETC installation: Do not obstruct the view; it is 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 right side of the rearview mirror 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 for self-charging. Therefore, during installation, avoid the black areas of 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 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, requiring a visit to an ETC service point for unlocking. 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 the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic payment for the preceding vehicle. The ETC lane recognizes a vehicle speed of 20 kilometers per hour; excessive speed 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 may also cause payment failure.
