Why does the ETC device beep?

[LeValerie]

Reasons for ETC device beeping: 1. The newly received device has not been activated yet; 2. It is normal to hear beeping when driving on highways, as this records the trip for convenient toll collection when exiting; 3. The device may have low battery due to shipping and storage time. ETC (Electronic Toll Collection), also known as automatic road charging system, is a dedicated road tolling method typically used on highways, toll bridges or tunnels, and certain urban sections to alleviate traffic congestion. ETC works through microwave-based dedicated short-range communication between the vehicle's windshield-mounted electronic tag and the microwave antenna at the toll station's ETC lane, utilizing computer networking technology for backend bank settlement, enabling vehicles to pay tolls without stopping at highway or bridge toll stations.
