My best guess is that the screws holding the device together are beneath the black frame. It's held on with double sided sticky tape (much like the Eken M003 - go check the post from Asure in the M003 section). Maybe somegentle heat to loosen the tape and gently (GENTLY) peel back the frame. That's my best guess - haven't done it myself, but might to cure a dust bunny problem.
