  • Removing the cover for the battery may be stiff and you may need to push with your thumb on the one end to slide it open with a small degree of force. The cover slides to the side and then slightly forward to unhinge two tiny hinges that help to hold the cover in place.
  • Closing the cover for the battery may be tricky – you may need to look at where the small pins are located at the top and bottom of the cover to ensure they are lined up to click in when sliding the cover back into place.
