Open apart the Lens part

My GC-200 has dust inside the lens, but didnt have any problem with anything

ive read the disassemble of this camera but i dont see anything related to opening the lens

here is a sample image i took , see the black thingy? that's the dust , it just wont go off even if i blew on it

and no its not a scratch , i can clearly see a dust from the front side of the cam
