Cannot access Music and Voice menus

The root folder may be the culprit on this one. My advice is to add tracks like so Artist>>Album>>SONG.mp4 root folders can only accept x files

Download the special firmware of your daughter's device , after that you shouldn't forget to restart it . The special firmware could be found on the manufacturer website .

cant get setup disc to load

to delete files there are 2 ways to do this.(1) first is with the on and facing you. on top the is the black menu switch. (2)hold down until it reads play music,and release (3) cycle either way until it reads delete.(4) cycle the switch until it reads del / push switch in (5) cycle to voice (6) push switch in to delete files. (cycle to exit and push switch again it should go to your music.

Second way is to plug it into a computer with plug and play.with the Trio MP3 on, the computer should open up a menu, chose open files (2) the screen should have music, voice and other files on the display. chose the voice file and click it open. use the mouse to delete files / or point and use the key board delete key to delete files. IF PLUG and Play does not open up goto MY Computer and openit up. drop down to the removeable disk and click open. you should be where you can delete the voice file. good luck and have fun.

This is quite simple. Just go to Music Library and way at the bottom "Recordings" now highlight the ones you need to delete and hold either the "Play/Pause" button or the "Back" button (sorry mines been broken havent used it in a while i cant remember) and scroll down to reset. Hope this helped...

Do this procedure for "voice" mode to delete voice recordings:

Delete file (stop submenu) - Delete corresponding files and save files in Music mode, Voice mode or FM mode.
1. In stop interface (FM without stop interface)
2. Short press "MODE" to enter stop submenu
3. Click "NEXT" or "PREV" to choose "single" or "all" files
4. Short press "MODE" to enter the Delete interface
5. Click "NEXT" to change "no" into "yes"
6. Short press MODE to confirm the delete prompt
"Delete all" will delete all related files stored in the selected folder. For example, if in music mode "Delete all" will delete all the music files, while other recorded files (e.g. voice recordings or FM recordings) will not be deleted.
Likewise, if "Delete all" is used when in the "Replay" menu, this will delete all recorded files but leave music files intact.
FM is much simpler – "Delete" or "Delete all" will delete the station(s) saved before.

ok...here goes...

go to "My Computer"

Right-Click the "Removable Disk" icon, and scroll down to "Properties"

click "Properties" and another window will appear. There are Tabs at the top of the window. click the "Tools" tab.

select the "Check Now" function located next to the "Error-Checking" option. ANOTHER window will appear.

select "Automatically fix file system errors" and click "Start".

This takes around 15 seconds and usually fixes the problem. you will then be able to add/delete files in the MP4 player.

Go into my computer, and plug in your mp3 player into the computer. You should see a new button for the mp3 plyr (drive e, i think) click it. U can delete the files form there.
