What to do if the Bluetooth column is not displayed?

Question

Bluetooth

I bought a phone for my father for his birthday and they gave me a cheap bluetooth speaker as a gift, and it turns on, but bluetooth is not displayed anywhere. I tried 2 phones and a computer, and the column is not displayed anywhere.
1. There is no bluetooth connection button, it starts looking immediately after it is turned on.
2. the speaker is charged
3. there is not even a word about the combination of keys that reset the speaker settings

Answer 1

Are you sure that when you turn on the column automatically turns on the search? give a photo of the buttons
