Baofeng DMR DM-1706

Greetings everyone. I’m new to the forum. I’m also a new amateur radio operator. My first device is Baofeng DM-1706 . I spent a lot of time programming the device. I finally discovered that he programmed it with the CPS CH6-DMR. I loaded the frequencies I wanted to my device. But right now I can’t see the names of the channels I added on my device. CH MODE is not available on the device. I couldn’t find it though. I want to do a software update to the device but I couldn’t find it. I’m waiting for your help.
