Does installing ETC in the black area affect its usage?

[McEvelyn]

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 detection equipment. However, installing it on the black dotted area of the windshield also has drawbacks, namely that the solar charging capability of the ETC device may weaken, and over time, it might run out of power. For small cars, the ETC is generally installed 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. 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 window strip. Here are some considerations 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 can reduce the driver's field of vision. If the ETC is installed without considering this, it can increase the driver's blind spot. 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 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 might block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-tamper 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. 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 area 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 sensing and paying 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.
