How to set the voice broadcast of mobile payment

First of all, we need to open our WeChat, click on I Click Service in the lower right corner, click Pay First, and then receive the payment. This page has a QR code to receive payment. This is the QR code of our collection. People just need to turn on their mobile phones, and they don't need to add us as friends. Scan it and you can pay us. There are three points in the upper right corner of this page. When we click on it, there will be a voice reminder to open the collection and payment. When we click this switch, there will be a prompt to confirm that the media sound has been turned on. Media volume is the ringtone of our mobile phone. On the side of the mobile phone, there are volume up keys and volume down keys. We pressed the volume up button and turned the volume up to the maximum. We can also click on this small arrow, and the bell can be turned to the maximum in this box.
