How to continue using ETC after it falls off?

[DeElisa]

ETC needs to be reactivated after it falls off and is reinstalled. The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and the 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 front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick 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. The chip should be inserted into the OBU device. Method to activate the ETC device: Insert and remove the ETC card twice until the electronic tag screen displays "Bluetooth On." If the screen shows "Tag Invalid" when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth directly. Turn on your phone's Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag). Navigate to the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt.
