i have a worn out mzn-505 and the key pad is all screwed up- next means back and so on- all this is fine and i understand but sometimes when i push a button, the "mk on" comes on and it makes a new track right in the middle of the song- not a big deal but it bugs me- anyway is there a way to erase the track mark so it would be one complete song again- thanks for any help
