4. How to Use the GXA-23
4.1. GXA-23-PRINT and GXA-23-REZERO
Connect the plug of the foot switch to either jack on the
option board panel.
Connecting the plug of the PRINT foot switch enables the
switch to perform in the same way as the PRINT key.
Connecting the plug of the REZERO foot switch enables
the switch to perform in the same way as the RE-ZERO
key.
Either of the jacks can be used because the wiring
inside the plug determines the function.
The balance function setting is not used.
