Where is the ETC switch located?

[Edward]

ETC switch is generally located on the top of the ETC electronic tag. 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, the red light will briefly light up, and the OLED screen will display "Tag Invalid" or "Please Insert Card", indicating 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 film 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 area should be inserted into the OBU device. ETC activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth On". If "Tag Invalid" appears when inserting and removing the card twice without the electronic tag attached, it is normal and does not affect activation. Alternatively, you can directly press the button on the top of the electronic tag to enable Bluetooth. Turn on the mobile phone's Bluetooth, open the corresponding mobile APP (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click on device connection and wait patiently for the "Connection Successful" prompt. After successful connection, upload a photo of the vehicle's front to complete activation.
