Where is the OBU Bluetooth switch?

[LeVera]

The OBU Bluetooth switch is a button located on the top of the OBU device, which serves as the power switch for the device's Bluetooth. After pressing it, the Bluetooth indicator light will flash and then remain steadily lit. Below is some relevant information about OBU: 1. Introduction: OBU stands for On-Board Unit, a microwave device that communicates with RSU (Roadside Unit). In the ETC system, the OBU is placed in the vehicle, while roadside units are installed along the road. They communicate with each other via microwave signals. When a vehicle passes through an RSU at high speed, they communicate via microwave signals to verify authenticity, identify the vehicle type, calculate toll rates, and deduct the toll fee. 2. Precautions: If a vehicle travels between tall buildings, the GPS and GPRS signals can be easily blocked by the buildings, significantly affecting GPS position calculations and GPRS wireless communication. This may result in delayed or failed transmission of the vehicle's operational status and location to the headquarters, and similarly, the headquarters' dispatch information may be delayed or fail to reach the terminal. Consequently, this can lead to inaccurate scheduling and reduced efficiency in dispatch control.
