The ETC installation position for small cars 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 to 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 driving license. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the driving license should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed. The vehicle must be under the name of an individual aged between 18 and 60. For units or companies, an organization code certificate (or business license) and official seal are required. Here are the precautions for installing ETC: Do not block the view; it is best to install it behind the rearview mirror: Many car models have a large tilt angle on the windshield, which can reduce the driver's field of vision. If this is not considered when installing ETC, it will increase the driver's blind spot. Install it behind the right side of the rearview mirror to avoid blocking 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 may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal rod connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal rod in. If it is removed arbitrarily, the rod 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. 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 in front to avoid automatic toll payment for it. The ETC lane recognizes a speed of 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 linked to ETC, insufficient balance will also cause payment failure.
