Can ETC be attached at the black dot area on the windshield?
1 Answers
The black dot area on the car's windshield should not be used for ETC installation, as this position may obstruct the solar panel behind it from receiving sunlight. Additionally, the chosen ETC installation location must not interfere with the driver's line of sight. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device should be installed on the upper middle part of the windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and a red light will briefly illuminate. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is properly inserted into the OBU device.
