The installation position of a car ETC is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed 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 anti-explosion film or those that have it installed later, it may affect the signal transmission of the microwave communication link, so it should be installed in the microwave skylight strip. ETC is the abbreviation for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If it's not the owner applying, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for installing ETC: Do not obstruct the view; it's best to install it behind the rearview mirror: Many car models have a large tilt angle of the windshield, which can reduce the driver's field of vision. If this is not considered during ETC installation, it can 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, it 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 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-removal guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed arbitrarily, the guide rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You would then need to go to an ETC service point to unlock it. This 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 in front to avoid automatic sensing and paying for the front vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may prevent the vehicle device information from being read, leading to a failed transaction. When using a debit card linked to ETC, insufficient balance can also cause the transaction to fail.
