Can ETC be installed in the black area of the windshield?

[StEsther]

ETC devices should not be installed in the black dotted area of the windshield as it affects normal operation. Installing ETC in the black dotted area has drawbacks, mainly weakening the solar charging capability of the device, which may lead to power depletion over time. Additionally, it's important to ensure that the ETC installation does not obstruct the driver's view. The optimal placement is directly behind the rearview mirror inside the vehicle, ensuring both functionality and aesthetics. For passenger cars, the ETC is typically installed in the upper middle section of the windshield, while for large vehicles like trucks and buses, the installation position is in the lower middle section. The suitable installation height ranges between 1.2 meters and 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket anti-explosion films, which may interfere with microwave signal transmission, the ETC should be installed in the microwave window strip area. Here are key considerations for ETC installation: Avoid obstructing the driver's view, best installed behind the rearview mirror: Many vehicle models have windshields with significant rearward inclination, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Placing it on the right side behind the rearview mirror helps avoid view obstruction. Ensure uninterrupted charging: ETC electronic tags consume power but generally don't require manual charging or battery replacement as they feature a built-in solar panel for self-charging. Therefore, avoid installing in the windshield's black areas or positions that might shade the solar panel. Do not remove once installed: The adhesive backing contains an anti-tamper rod connected to a switch. When properly installed, the windshield presses this rod in. Removing the device causes the rod to pop out, triggering the switch and locking the tag, requiring an ETC service center visit for reactivation. This mechanism prevents multiple vehicles from sharing one device. ETC usage notes: The ETC transaction sensing range is 8 meters. Maintain at least 10 meters distance from the vehicle ahead to prevent erroneous charges if their ETC malfunctions. ETC lanes recognize vehicles at speeds up to 20 km/h; excessive speed may cause read failures. For debit card-linked ETC, insufficient balance will also result in failed transactions.
