Welcome to the site!
This belongs in the audio forum so 1st Mp3 can help you out, but you are new so we'll cut you some slack
This is how I answered it for another fellow forum member.
See if it works for you too.
Re: clock
Okay, I'm no guru on this matter but I did get mine to display and change things around all the time....
Here are he steps (I'm sure there are other ways but this worked for me)
1. Menu (hold down)
2. Scroll to DISPLAY TYPE with AM FM buttons
3. Hold down Back track button until inside Display type Menu
4. Select Display Type B
5. Menu (hold down)
This will make your display very simple (no flashy stuff) and allow you to select what you display beyond pictures and eq's. Go back into the Menu
1. Menu (hold down)
2. Select DISPAY MODE (different than DISPLAY TYPE and only comes up as an option when in type B)
3. Hold down Back Track button to enter DISPLAY MODE
4. Should be options by pressing AM,FM, and Track Back/Forward buttons.
5. You want the options to display clock....It may show DNPS + Clock + Name or whatever you like, but to have the Clock it must be one of these in the list
6. Once you have clock selected as a display mode you can hold down menu and return to the regular screen to see if it appears
7. Once that is complete you should have a clock display and can go back and chose any DISPLAY TYPE you want. i.e. A, B, or C but the clock can always be shown if you press the pause button or are between tracks.
I leave mine to show the EQ and all I do when I want the clock is press the pause button or wait between tracks. If the settings are to off the Clock will show on mine.
Just play around with what I listed. If it doesn't work let me know and I will try to help you more. This probably isn't the only way but it worked for me.
Let me know if it works out!
