How long after window tinting can ETC be installed?

Generally, you need to wait about a week after window tinting, until the moisture inside the tint has completely evaporated, before installing ETC. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly illuminate. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating that the device is functioning normally. Clean the front windshield to ensure the glass 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 facing the driver and the back facing the windshield, ensuring the chip is properly inserted into the OBU device.
