User defined on-grade level:
An arbitrary level within -10 and +40mm around the
marking notch can be used as on-grade level. The user
defined on-grade level is set by pressing the accuracy
button [17] for two seconds while the device is in the
laser beam. If successful, you will hear a confirmation
beep and an asymmetric arrow symbol is shown on the
display. Outside the allowed area you will hear an error
beep and error code E30 is shown.
When the accuracy button [17] is pressed for two
seconds while out of beam, the on-grade level is reset
to default. If the device is switched off, the on-grade
level is automatically reset to default. If you want to
save the user defined on-grade level permanently, you
can choose this option in the menu (see Menu Entries -
.OFS).
