What does the scan button on a car mean?

[VonDaniela]

The electronic screen in the car displays SCAN, which means scanning, i.e., searching for radio stations and then stopping to listen to the current station. Here are the specific details: 1. The original meaning of SCAN is 'to examine carefully, to scrutinize,' etc. In the car, it represents scanning and searching for radio stations, meaning it searches for stations and then stops. 2. SCAN: When pressed in CD playback mode, the display shows the word SCAN, and the music will start from the next track of the currently playing music, scanning through each track for a few seconds before moving to the next track in a loop. When the user hears a track they like, pressing this button again will make the player start playing from that track. In other words, pressing SCAN makes the car scan and search for all receivable radio broadcasts. The radio will switch to a station, stop there for a few seconds, and then jump to the next station. Pressing the SCAN (search) arrow will stop the search and allow you to listen to the current station.
