User defined on-grade level
An arbitrary level within-10 and +10 mm around the Marking notch [6]can be used as on-grade level.
§ Hold the Accuracy/Arrow down button [17]for two seconds while the device is in laser beam.
§ The device beeps one time, and an asymmetric symbol arrow[20]&[21]appears on LCD display[10].
This means the user defined on-grade level succeeds.
§ When the laser beam is outside of allowed area (10 and +10 mm), you hear one beep sound and text
‘E30’ appears on Numeric digits/text display[19]. This means user defined on-grade level fails.
§ Reset user defined on-grade level to default
