The out-of-level indicator 37
flashes during automatic
leveling.
– Wait until the measuring tool is leveled in.
– Use the laser receiver to find the center
line and transfer the height “X1” of the
center line onto the wall.
– Turn the measuring tool 180° without
adjusting the height of the tripod.
– Wait until the out-of-level indicator 37
stops flashing and the measuring tool is
leveled in.
– Use the laser receiver to find the center
line and transfer the new height “X2” of
the center line onto the wall.
– Determine the exact center between the
center lines “X1” and “X2” and position
the laser receiver on it using the center
mark 16.

– Press the slope button 18
or 20 until the center line
indicator 43 lights up
continuously. If the audio
signal is switched on, a
continuous tone sounds.
– Press the calibration button
25 to save the calibration.

The symbol for completing
calibration is shown on the
display.
– Check the leveling accuracy after
calibration (see “Checking the Leveling
Accuracy in the Horizontal Position”,
page 27). If the deviation is still outside
of the maximum permitted limit of ± 1/16
in (± 1.5 mm), have the measuring tool
checked by a Bosch customer service
agent.
Y-Axis Calibration
– Mount the measuring tool in the horizontal
position on a tripod 63 (accessory).
– Place the tripod 100 ft (30 m) in front of
the wall. The Y-axis indicator imprinted
on the measuring tool must be pointing
perpendicular to the wall.
– Switch the measuring tool on.
/
/
/
/
– Simultaneously press the
calibration button 25 and
the slope button 20 for
approx. 2 s.
