  4. push both egdes of the slide area outwards, to totally remove this slide cover
  5. further more, now push both the above slide edges even more .. till bottom of (front face) cover loosens up. Whilst lifting this only a little at a time ...
  6. Gently remove /loosens only lower ends (only at this stage) of the 2 silver edge stripes... by .. lifting up (away from face of remote) ..whilst .. moving them outwards. ** i.e up, then outwards) Do not remove top edge of silver tip yet
  7. start separating left n right egdes with sharp flat point from under silver side strip, " digging" downwards towards bottom of remote
  8. At this point, the top edge of remote may be separated, but not necessary.. if you can pull insides out from bottom, PREFFERED OR .. can be done by:
  9. using flat edge - loosen/pry 1cm from corner on top tip of edge left n right digging downwards n outwards towards bottom of remote .. enough gap to use a little pressure if you must
