The soft key functions are pre-assigned to default values in four groups, as indicated below.

These groups can be accessed by pressing the “NEXT” soft key. The “NEXT” key is assigned to

the bottom, or #7, soft key.

The soft keys may be re-assigned functions as per the requirements of the operator, thus allowing
