How to Turn On the Bluetooth of an ETC Device?

The method to turn on the Bluetooth of an ETC device: 1. The ETC Bluetooth switch is a button on the top of the electronic tag. Press the button to activate the Bluetooth of the electronic tag; 2. Insert and remove the ETC card twice in succession to turn on the Bluetooth of the ETC device. A successful activation is indicated by the Bluetooth switch indicator on the ETC electronic tag flashing or staying lit for about 2 minutes. Please complete the relevant Bluetooth connection as soon as possible. The Bluetooth function of the ETC device is only used for ETC activation or recharge. Automatic deduction through the high-speed ETC lane does not require the Bluetooth to be constantly on. The ETC device has an internal battery and is charged externally via solar power. For solar-powered ETC devices that are not frequently used, it is recommended to charge them every 3 months to prevent natural discharge of the internal battery.

How to Remove an ETC Device?

Method for removing an ETC device: Since there's double-sided tape on the back of the device, you can use a hair dryer to heat it up, then gently pry it off with a small plastic scraper, and finally wipe it clean with a cloth. Note that self-removal will deactivate the ETC device, requiring reactivation at the issuing institution with the vehicle's registration certificate. ETC stands for Electronic Toll Collection, an automated system that identifies vehicles, records information, and deducts fees from pre-linked IC cards or bank accounts when passing through toll stations.

How to Check the Condition of a Car Battery?

Methods to check the condition of a car battery: 1. Inspect the exterior for any deformities, bulges, leaks, cracks, burns, or oxide seepage around screw connections; 2. If the exterior appears normal, operate the UPS in battery mode with a certain load. If the discharge time is significantly shorter than normal, and the battery cannot restore normal backup time after 8 hours of charging, it indicates battery aging; 3. Use a multimeter for measurement. The car battery is a crucial component of the vehicle's electrical system. If the battery malfunctions, the immediate symptom is the inability to start the vehicle, especially in automatic transmission cars. When the battery voltage is too low to start the engine, the only solution is to jump-start the car, which can be quite troublesome.

B-Class License: If the new energy vehicle is a medium-sized passenger vehicle or a large truck, a B-class license is needed. 3. A-Class License: If the new energy vehicle is a large passenger vehicle, a tractor, or a city bus, an A-class license is required. Additional Information: 1. Introduction to New Energy Vehicles: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or conventional vehicle fuels with new on-board power devices), integrating advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles, new technologies, and new structures. 2. New energy vehicles include four major types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices).
