This morning I made a backup of my parameters and noticed the backup file doesn't appear to contain any 900 option parameters. This is the method I used:

CNC Go into EDIT mode.
CNC Press ESTOP.
CNC Press the <, SERVICE, CHAPTER, PARAMETER, >, READ, ALL keys.

What do I need to do to view/punch my 900 option parameters on a 15M? On the 0T I hold down the EOB but not sure on this machine.
