What does label removal mean?

[MacJasmine]

OBU device's anti-tamper button on the back pops up and locks. Here is the relevant introduction about label removal: 1. Introduction: There is a locking button on the back of the device. Once the OBU falls off the front windshield, the locking button will activate, causing the ONU to become unusable. If the OBU falls off, it needs to be reattached, and then reactivated at the highway management office's ETC service point. 2. Recovery method: Self-activation method: Most ETC devices will not become invalid. At this time, you can boldly remove the electronic tag, or you can press the electronic tag tightly with your hand, and then use a wall knife to cut the double-sided tape and the bonding surface of the windshield. During the whole process, be careful to avoid the ETC anti-tamper switch from popping up. 3. Business hall activation method: Start the ETC system software, insert the ETC white card into the card slot, enter the owner and vehicle model information in the system, click the card making button, and then take out the card slot.
