Most of the keys have two functions according to whether the sample
changer is in the normal state or in edit mode.
The uppermost row contains the (<CONFIG>, <PARAM>, <USER
METHOD>) keys which make the menus accessible. Here with the help of
the keys on the left side of the keyboard, you can navigate and change pa-
rameters. For the latter, the numerical keypad on the right half of the key-
board is available. Except for the menu “User Method” the entries under
these selection menus can be altered while a method is in process and for
the most part, have an immediate effect on the procedure which is running.
The lowermost row of keys (<HOLD>, <STOP>, <START>) are used
for the direct control of method processing.
