The first step is to open our own mobile phone, and then download a cool dog player on the phone, if the download is installed, then we find the software directly on the desktop, and then open.
Then after we open the main interface to the phone's cool dog, we'll click on the main screen for more button options in the upper right corner.
After we open more items, we see some adjustment options under this option, and of course here we need to note that there is a timing option.
Then when we see this option, we click on the timing options to open, into the timing options to set the interface, the interface will appear some fixed time options and custom time options settings.
We randomly choose a try, such as our choice of one hours, after the selection, there is an interface to remind us to stop playing after 59 minutes.
We notice that one option is to stop the song playing, and there is a regular exit from the cool Dog music option, when we choose the second one, we see the regular shutdown of the cool dog music is selected, or click on the customization above, the time to determine their own, determined after the successful settings.
