c240 Battery Removal

I’ll probably have it figured out before I read a response, but… my daughter’s c240 froze up while charging.  My first instinct is to remove the battery and replace it back, but I’m having trouble getting the battery cover off.  Is there a recommended method and is there an easy way to do it?

before you remove the battery, try performing a soft reset on the player.  just press and hold the menu button(power button) until the player turns off.  if that does not work, slide the back of the player away from the head phone jack.  **little trick on gripping stuff, wrap a rubber band around your thumb a couple of times, and push the case down, sounds stupid, but works like a charm**
