Taking the Industrial and Commercial Bank of China's ETC as an example, the Bluetooth switch is generally located in the upper left corner of the device. Press and hold it to activate the Bluetooth function. Here are some precautions for using ETC devices: 1. Device inspection: Before installing the ETC device, check for any damage, especially whether the ETC device can properly activate Bluetooth mode. 2. Normal operation: Turn on the ETC device. If the screen displays "Label Invalid," it indicates the ETC device is functioning normally. After inserting the ETC card, if the balance is displayed, it means the device is ready for use. 3. Power supply: There is no need to worry about the power supply of the ETC device, as it is usually charged via a solar panel. If the battery is damaged, simply replace it. Normally, there is no need to concern yourself with shutting it down.
