The ETC is generally installed in the upper middle part of the front windshield, while for large vehicles such as 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 explosion-proof film or those that have it installed later, it may affect the signal transmission of the microwave communication link, and thus should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle license. If the application is not made by the owner themselves, the agent's valid ID card is also required. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle license; Vehicle for which ETC is to be applied. Here are the precautions for installing ETC: Do not obstruct the view, it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spot. Install it behind the rearview mirror on the right side to avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not need to be charged or have its battery replaced because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not install it in a position that easily blocks the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal lever, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed casually, the anti-removal lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Precautions when using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, keep a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The recognition speed for ETC lanes is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, leading to payment failure. When using a debit card bound to ETC, insufficient balance will also cause payment failure.
