Keycap Change for Eos 3.X on Ion Classic Consoles
With the introduction of Eos 3.0.0 software, one of the keycaps on your console will need to be changed.
Instead of the "Scroll Lock" key, Eos 3.0.0 uses a "Stage" key.
For Ion and Element (not Element 2) consoles, the part number for the keycap replacement kit is 4310K1025. The kit includes the keycap, a key puller, and instructions. If you only need the keycap the part number is 4310A2008.
