User defined on-grade level:
An arbitrary level within -10 and +40mm around the Centre notch
can be used as on-grade level. The user defined on-grade level is
set by pressing the accuracy button for two seconds while the de-
vice 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 is pressed for two sec-
onds 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.
