What to Do When the Dash Cam Screen Doesn't Light Up?

Many people have encountered the issue where a dash cam fails to power on normally. There are generally two reasons for this: either the dash cam itself is faulty, or it is not receiving power. If the dash cam is broken, you can contact customer service or simply replace it. However, most modern dash cams come with built-in batteries. The purpose of these batteries is to allow the dash cam to delay shutdown and continue recording for about a minute after the car is turned off. Some dash cams even offer a parking monitoring feature. However, relying solely on a built-in battery of 200-300 mAh for parking monitoring isn't very reliable. Therefore, the most likely reason a dash cam with a built-in battery won't power on is that the battery is depleted. Most dash cams today have a battery protection setting. When the built-in battery is completely drained, even if you connect the dash cam to the car charger, it won't power on immediately. The reason is simple: the battery has no charge left, so it needs to be charged slightly before the dash cam can power on normally. In such cases, waiting for about half a minute to a minute should suffice. Once the built-in battery has stored some charge, the dash cam will automatically power on. Although the dash cam is always plugged into the car charger while in use, the battery can still drain significantly due to parking monitoring. Some dash cams have parking monitoring but aren't connected to the car battery, relying instead on the built-in battery. A 200-300 mAh battery can only record for about ten minutes if the car is disturbed at night. Once the battery is fully drained, the dash cam won't power on normally. Another scenario that might prevent the dash cam from powering on is extreme temperatures. Different products have varying standards for high and low-temperature resistance. Therefore, in extremely cold winters (e.g., -20°C at night in northern regions) or extremely hot summers (e.g., over 60°C inside a car exposed to direct sunlight), the dash cam may not power on normally. In such cases, you'll need to wait until the temperature stabilizes (typically between -10°C and 40-50°C) after turning on the air conditioning, at which point the dash cam should function normally.

Where is United Trucks manufactured?

United Trucks is an emerging heavy-duty truck brand in China, located at No. 8 Huadian Avenue, Sanshan District, Wuhu City, with a total project area of 3,500 acres. United Trucks adopts the self-developed "UE" platform, which is synchronized with mainstream global heavy-duty trucks, using world-class heavy-duty truck products as benchmarks. The main participants of United Trucks include CIMC, Chery Automobile, Yuchai Group, Fast Group, and Fuwa Heavy Industry. These five enterprises are respectively China's largest logistics equipment and special vehicle manufacturer, China's largest independent brand automobile manufacturer, China's largest diesel engine manufacturer, China's largest heavy-duty truck transmission manufacturer, and China's largest axle manufacturer. These five heavyweight enterprises in China's automotive industry have joined forces to enter the heavy-duty truck sector. The logo of United Trucks is a shield-shaped mark with two layers of meaning in its design. The first interpretation is the letter "U" in English, the initial of "United," representing unity, as we are called United Trucks. Another interpretation can be seen as two opposing "C"s, C&C. This further contains three explanations: first, it represents the two shareholders—CIMC, whose initial is "C," and Chery, whose initial is also "C"; the second explanation is Chinese Car, also "C"; the third explanation is creation and innovation, with "create" (innovation, creation) starting with "C." In terms of symbolism, "U" represents unity. United Trucks aims to integrate resources in competition, expand competitive advantages, and create harmonious and win-win cooperative relationships through strong alliances. It fosters a team spirit of collaboration and builds united, efficient teams; the two "C"s facing each other form the "light of discovery," symbolizing the company's commitment to technology and innovation; the overall shape can also be seen as a pair of steel wings, symbolizing the company's soaring ambitions and limitless future; additionally, it can be viewed as a shield, representing the robustness and strength characteristic of heavy-duty trucks.

Can a Beginner Pick Up a Car Alone?

Of course you can. There is no legal requirement for how many people should pick up the car together, but it is recommended to have an experienced driver accompany you. Beginners may have many things they don't understand, and an experienced driver can help offer advice. The first thing to check when picking up the car is the exterior. First, take a general look at the car body to see if there are any obvious external damages. Then carefully inspect the paint surface for scratches. Pay special attention to the four corners of the car and the bumpers, as any scratches or similar issues will definitely leave marks on these areas. There are four numbers on the tire. The first two digits represent the production week, i.e., the week of the year it was produced, and the last two digits represent the year. For example, if it's 2017, the last two digits will be 17. If it reads 2417, it means the tire was produced in the 24th week of 2017. Then check if the tire shows signs of wear and whether the tread is clear. If the tire has been used for a long time, it will be obvious at a glance. Ensure all documents and materials are complete. These will be needed for future procedures like license plate registration and insurance purchase. These include the warranty card for the main three-guarantee service, the car purchase invoice (usually in triplicate), the vehicle certificate, the vehicle user manual, etc. Finally, make sure the numbers on the documents match the engine number and chassis number on the car.

How to Use an ETC Card?

Insert the stored-value card into the electronic tag to enjoy toll payment without stopping. Below are specific details about ETC: 1. Composition: ETC, translated into Chinese as electronic toll collection, is an automatic toll system for highways or bridges. It uses dedicated short-range communication between the vehicle's electronic tag and the microwave antenna in the ETC lane at toll stations, combined with computer networking technology for backend settlement with banks, allowing vehicles to pass through highway or bridge toll stations without stopping to pay fees. 2. Current Status: ETC is an electronic automatic toll collection system being actively developed and promoted internationally for roads, bridges, and tunnels. This technology has a long development history abroad, with electronic toll systems in the U.S., Europe, and many other countries and regions already partially networked and gradually achieving economies of scale. In China, the highway toll collection system, which primarily relies on manual toll collection using IC cards and magnetic cards as media, is undoubtedly influenced by this trend.
