The correct process for installing an electronic ETC is as follows: Purchase the ETC device, check if all components are complete, and review the installation manual. Determine the installation direction of the ETC device, with the solar panel facing outward. Peel off the adhesive backing of the device, align the solar panel with the vehicle's front windshield, and press firmly to ensure secure attachment. It is best to install the device at the top center of the vehicle's front windshield, ensuring it does not obstruct the driver's normal view. Once attached, it should not be removed and reattached. Finally, insert the ETC card to activate the device. Upon hearing a beep and seeing the indicator light, the device is activated. Here are some precautions for ETC installation: Avoid obstructing the driver's view. The best location is behind the rearview mirror: Many car models have windshields with a steep angle, which can reduce the driver's field of vision. Installing the ETC without considering this can increase blind spots. Installing it behind the rearview mirror on the right side helps avoid blocking the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel for self-charging. Therefore, avoid installing it on blacked-out areas of the windshield or positions that might block the solar panel. Do not remove the device once installed: The adhesive has an anti-tamper button connected to a switch. When installed, the windshield presses this button in. If removed, the button pops out, triggering the switch and locking the device, requiring an ETC service point to unlock it. This prevents multiple vehicles from sharing one device. ETC usage notes: The ETC transaction sensing range is 8 meters. To avoid issues caused by a malfunctioning ETC device in the vehicle ahead, maintain a distance of at least 10 meters to prevent automatic payment for the wrong vehicle. The ETC lane recognition speed is 20 km/h; exceeding this speed may result in failed transactions. If using a debit card linked to ETC, insufficient balance can also cause payment failures.
