====== Inside an Ergodex DX1 ======

I decided to throw caution to the wind tonight and cracked open my DX1, blatently ignoring the warning sticker on the back of the DX1 that reads **"Under no circumstances should this label be removed. ... Tampering with or removing this label will nullify all product warranties and will likely cause your DX1 Input System to malfunction"**.  I'm happy to report that my DX1 is still functionaing perfectly after this procedure.  The label itself is metal backed so probably does serve some purpose, personally I cut a slit into my label around the center hole (under which is a screw that needs to be removed before the unit can be opened) so that I could fold the label back down again.
