What is the suitable installation position for ETC?

[SanHarper]

For small cars, 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 at a height of no less than 1.2 meters and no more 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, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC is an electronic toll collection system that enables vehicles to pass through toll gates without stopping. It uses dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and then processes the payment through computer networking technology with the bank. 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 windshields with a large rearward tilt angle, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not affect 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 do not place it where the solar panel might be easily obstructed. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to go to an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. Things to note when using ETC: 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 sensing and paying for the vehicle ahead. The speed limit for ETC lane recognition is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and cause payment failure. When using a debit card linked to ETC, insufficient balance may also lead to payment failure.
