How to Fix Continuously Playing Car Audio?

Here are the solutions for continuously playing car audio: 1. Turn the volume potentiometer to the lowest level. If there is a humming sound, it may be caused by the altered or insufficient capacity of the electrolytic capacitor in the amplifier's filter circuit. If there is a loud humming sound when the volume is increased, it is likely due to poor shielding of the amplifier's audio input. Check and fix the shielding issue. 2. Ensure that all component casings are properly grounded, and use shielded cables for audio input lines with good grounding. 3. If there is a hissing sound from the speakers, it is mostly due to poor overall shielding or inadequate isolation between the primary and secondary windings of the power transformer. Try reversing the power plug or connecting two 4700p capacitors with a working voltage of 250V in series at the power input, with the center tap grounded, to reduce noise.

How long should you wait to drive after smelling burning from brake pads?

If the brake pads are overheating and emitting a burning smell, it's best not to continue driving, especially at high speeds. You should drive the vehicle to a safe location, park it, and check for the cause or visit the nearest repair shop for inspection and maintenance. Below is relevant information about brake pads: 1. The working principle of brakes mainly relies on friction. By utilizing the friction between brake pads and brake discs (drums), as well as between tires and the road surface, the kinetic energy of the moving vehicle is converted into thermal energy through friction to bring the car to a stop. Therefore, any abnormal conditions with the brake pads must be addressed immediately. 2. Under normal driving conditions, the brake pads should be inspected every 5,000 kilometers. Not only should the remaining thickness be checked, but also the wear condition of the pads, whether both sides are wearing evenly, and whether they retract properly. Any abnormalities must be dealt with immediately.

When is the warranty period for car brake discs?

Brake discs are covered by warranty, typically for 12 months or 60,000 kilometers. Of course, the warranty period varies among different car brands. Here is some extended information: 1. Brake pads are wear-and-tear parts and generally not covered by warranty. The warranty time and mileage for various car components can be found in the vehicle's user manual. 2. The warranty time and mileage for different car components also vary by brand, as there is no unified national regulation. 3. Regarding whether the warranty is based on time or mileage, the general standard is whichever comes first. There are no specific national laws on this matter, and this is the current industry practice, not a deliberate evasion by 4S stores.

Is it mandatory to purchase vehicle and vessel tax and compulsory traffic insurance?

Yes, it is mandatory. The vehicle and vessel tax is included in the cost when purchasing compulsory traffic insurance, which is a mandatory insurance required by the state. Without purchasing it, you are not allowed to drive on the road. Otherwise, according to the "Road Traffic Safety Law," you may receive a warning or a fine ranging from 20 to 200 yuan. Article 95 stipulates: If a motor vehicle driven on the road does not display an inspection qualification mark or insurance mark, or if the driver does not carry the vehicle registration certificate or driving license, the traffic management department of the public security organ shall detain the vehicle and notify the party to provide the corresponding license, mark, or complete the necessary procedures. Compulsory Traffic Insurance: The full name of compulsory traffic insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates for personal injuries, deaths, and property losses of victims (excluding vehicle occupants and the insured) caused by road traffic accidents within the liability limit. The premium is based on the nationally unified standard. However, the price of compulsory traffic insurance varies for different vehicle types, mainly influenced by the number of car seats. Compared to the more than 20 exemption clauses in commercial third-party insurance, compulsory traffic insurance covers a much broader range, including losses caused by intentional acts of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses caused by accidents. Moreover, regardless of whether the insured vehicle is at fault in the accident, compulsory traffic insurance will compensate within the liability limit, with no deductible or exemption. Vehicle and Vessel Tax: Vehicle and vessel tax refers to a tax that owners or managers of vehicles and vessels within the territory of the People's Republic of China must pay according to the "Vehicle and Vessel Tax Law of the People's Republic of China." Starting from July 1, 2007, vehicle owners are required to pay the vehicle and vessel tax when purchasing compulsory traffic insurance. Introduction to Electronic Insurance Policies: An electronic insurance policy refers to a digital policy issued by an insurance company with an electronic signature, using digital signature software and enterprise digital certificates that comply with the PKI system. An insurance policy, abbreviated as a policy, is the official written proof of an insurance contract between the insurer and the insured. The insurance policy must fully record the rights, obligations, and responsibilities of both parties to the contract. The content recorded in the insurance policy serves as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks; Saves time and is convenient, unrestricted by time or location, with information accessible online anytime, quickly and easily; Allows for reissuance or resending, eliminating concerns about losing it. If a paper version is needed offline, it can also be printed or mailed; Facilitates management, as electronic unification makes it easier for insurance companies and traffic police departments to manage the insurance information of various vehicles.

Can only one ETC be applied for per car?

Only one ETC can be processed per vehicle. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Expressways" issued by the Ministry of Transport, the ETC application is related to the vehicle's driving license. If there are multiple vehicles under one's name, different driving licenses can be used to apply for ETC. Documents required for ETC application: The original valid ID card of the vehicle owner, the original and a copy of the vehicle's driving license (the page with the most recent annual inspection stamp must be provided). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a debit or credit card from the corresponding bank must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding ETC with a debit card. The vehicle insurance policy for the current year is also needed. For corporate applications, the agent's ID (or driver's license), the company's organization code certificate (or business license), and the company seal are required. ETC deduction principle: There will be one or more ETC lanes on expressways. Through microwave-specific short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, and using computer networking technology for background settlement with the bank, the vehicle can pay the toll without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and environmentally friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can improve vehicle passing efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles using ETC will be significantly increased." It also set a target in the "13th Five-Year" comprehensive transportation development indicators that "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the usage rate of ETC passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a stationary vehicle ahead, to prevent the ETC device failure or absence of an ETC device in the vehicle ahead, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle ahead. The speed for ETC lane recognition is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, leading to deduction failure. Unauthorized disassembly or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was processed or the highway service office for testing. Non-human-induced loosening or detachment only requires reactivation. When using a debit card bound to ETC, insufficient balance will also cause deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Poor sensing due to overly thick car windshields. Special attention is needed for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.
