Why Can't the Other Party Hear Sound on Car Phone?

[SanLondon]

There are multiple reasons why the other party cannot hear sound on a car phone. Here is a detailed explanation: 1. Reasons: The call volume on the phone is not turned on. You can try dialing a phone number and pressing the volume up button on the side of the phone during dialing or a call to increase the volume; The volume on the car navigation system is not turned on, simply turn it on; The car Bluetooth is not paired or connected to the phone at all. 2. Functions of Car Phone: The car phone has a voice-controlled hands-free function, avoiding the danger caused by using a mobile phone while driving. It has a DPS digital system that can filter out noise, making the voice clearer and preventing the driver's attention from declining, thereby avoiding the risk of collision. The antenna of the car phone is placed outside the car, and there is no electronic signal radiation inside the car. Since there is no electronic radiation signal inside the car, it will not interfere with the car's precision instruments, such as the ABS system and airbags.
