Help with my SDMX1-Stuck on Key Hold

Ok I dont know how this happened, but my MP3 player is stuck on Key Hold.  When I turn it on (press play)- “KEY HOLD” appears on the screen with a lock in a circle with a slash through it appears next to the text.

How do I fix this??? I have tried all kinds of stuff.

Any Ideas???

 at the side of the player, theres a switch and below it you will see “HOLD” and beside it and arrow.  just switch it to the opposite direction of the arrow to disable the lock.
