The method to set the horn sound when locking the Atz is as follows: 1. Turn on the horn sound when locking: You can use the remote key to turn on the horn sound when locking, which is to press the unlock and lock buttons simultaneously for 3 seconds. The light will flash once, and then only the light will flash without the horn sound. 2. Restore the horn sound: To restore, press the lock and unlock buttons simultaneously for 3 seconds again, and the light will flash once. 3. Turn off the horn sound when locking: Settings - Sound - Screen lock sound - Play sound when locking and unlocking the screen. The following is an introduction to other horn sounds: 1. Electromagnetic vibration to produce sound: The electromagnetic coil attracts the moving contact switch of the relay to close, and the current will flow to the horn. The current makes the electromagnet inside the horn work, thus causing the diaphragm to vibrate and produce sound. 2. Air horn: The air horn is mainly used in heavy-duty trucks with air brake systems. The electric horn has the characteristics of simple structure, small size, light weight, pleasant sound, and easy maintenance, so it is widely used in small and medium-sized vehicles.
