Keycap Change for Eos 3.X on Ion Xe and Ion Xe20 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 Xe, Ion Xe20, Gio @5, and some Gio, Eos Ti, and programming wings the part number for the keycap replacement kit is 4240K1025. The kit includes the keycap, a key puller, and instructions. If you only need the keycap the part number is 4240A2037.
For older Gio and Eos Ti consoles and programming wings, the kit is 4240K1026 and the keycap itself is 4240A2036.
To know which is correct for your Gio or Eos Ti console, open the control panel and look at the bottom of the circuit board for the keyboard. If the circuit board is white, you need the 4240K1026 / 4240A2036. If it's dark blue you need the 4240K1025 / 4240A1025.
