[DeColton]

AM on a car refers to the radio band of the car radio. The buttons and functions of the car radio are divided into: 1. POWER button: Press to turn on/off, rotate to adjust volume; 2. TPK button: MP3 track selection, browse playback tracks; 3. AST button: Long press to automatically store radio stations; 4. RPT button: Repeat playback; 5. INT button: Browse playback; 6. RDM button: Random playback; 7. SET button: Sound effect adjustment. The method to set the time on a car radio is: 1. Turn on the power switch; 2. Long press the volume button until the time appears; 3. Release the button and long press again, the hour light will flash; 4. Rotate the volume knob clockwise or counterclockwise to adjust the time.

AM in a car usually refers to the AM (Amplitude Modulation) mode of the radio, a traditional broadcast reception method. I often use it to listen to news and talk shows while driving, especially during long-distance trips. It’s more stable than FM and less prone to interference from tall buildings, making it suitable for listening in rural or mountainous areas, though the sound quality can be a bit noisy. Specifically, there’s a knob or button on the car dashboard or audio system for AM. You can switch to the AM band to tune into channels, such as classic stations like China National Radio News, which broadcasts on AM. Veteran drivers are particularly accustomed to this. If you notice AM stops working while driving, it might be due to poor antenna contact or signal issues, but it usually functions normally. Remember not to frequently change stations while driving—safety comes first. AM has a wide reception range and covers long distances, but many modern cars now also integrate new features like internet radio. Though old-school, AM’s high reliability makes it worth keeping.

AM in the car refers to the amplitude modulation function of the radio. As a young person myself, I initially thought it was some advanced feature, but it's actually a basic part of the radio. For simple operation, you can press the audio button in the car to switch to AM mode, where you can listen to local news or sports commentary. AM is better at capturing distant radio signals compared to FM. I often use AM to pass the time during my commute because it's less affected by tunnel interference. The sound quality may be slightly inferior, but the content is practical. The AM frequency band typically covers 540 to 1600 kHz—just turn the tuner to find your favorite program. If your car's AM has no sound, the antenna might be loose or a fuse could be blown. I've encountered this issue before, and a simple check of the connection points usually solves it. For maintenance, I recommend occasionally testing it to ensure the function works properly. Although AM technology is old, it's very useful in remote areas. I recommend trying old songs or morning news on it.

AM in the car refers to amplitude modulation radio. I've been driving for decades and have always enjoyed it as part of the radio function. AM has a muffled sound quality but offers wide coverage, allowing you to receive more local radio station broadcasts. All you need to do is press the AM button on the audio system, turn the tuning knob to select a channel, and you can listen to stories or weather forecasts. Older drivers like me are accustomed to listening to AM radio in the morning because it's reliable and the signal rarely cuts out. AM technology is simple but practical—just remember not to get too distracted while driving. If AM occasionally doesn't work, it might be due to battery issues or weak signals; I recommend rolling down the window to improve reception. This feature doesn't consume much power and requires no special maintenance. Although AM has been largely replaced by FM and internet radio, it still serves as a dependable old friend in the car.
