are connected via Bluetooth®. Start calibration by press-
ing the on/off button on the laser receiver and the centre
line mode button on the laser receiver at the same time.
"CAL" will appear on the display of the laser receiver.
Press the centre line mode button on the laser receiver to
cancel the calibration, if required.
To perform calibration without the app:
In the menu that appears in the measuring
tool display after starting calibration, select
the existing distance between the measuring
tool and the laser receiver. To do this, press
the buttons ▲ (4) or ▼ (3). Confirm your se-
lection with by pressing the slope but-
ton (14).
To confirm the selected measuring distance
( ), including the corresponding levelling
accuracy, on the display which appears,
press the slope button (14). To go back to
selecting the measuring distance (
the line operation button (5).
Align the height of the laser receiver so that the variable
laser beam (8) on the laser receiver is indicated as
"centred" (see operating instructions for the laser receiver).
Secure the laser receiver at this height.
Check whether the measuring tool and laser
receiver are aligned with each other, as illus-
trated on the display (the "+" side of the X-
axis is aligned to the laser receiver). Start
calibration of the X-axis with
the slope button (14).
If this step appears on the display, rotate the
measuring tool 180° so that the "–" side of
the X‑axis is directed at the laser receiver.
For each rotation, take care not to change
the height and position of the measuring
tool. Confirm the rotation with
ing the slope button (14). Calibration of the
X-axis continues.
This symbol will appear on the measuring
tool display if the X-axis has been success-
fully calibrated. "XOK" will appear on the dis-
play of the laser receiver.
Continue calibration with by pressing the slope but-
ton (14).
To calibrate the Y-axis, rotate the measuring
tool 90° in the direction of the arrow so that
the "+" side of the Y‑axis is directed at the
laser receiver. Confirm the rotation with
by pressing the slope button (14).
If this step appears on the display, rotate the
measuring tool 180° so that the "–" side of
the Y‑axis is directed at the laser receiver.
Confirm the rotation with
1 609 92A 55C | (05.11.2019)
Finish the calibration of the Y-axis with
slope button (14).
If the calibration has been completed successfully, the
measuring tool then automatically switches itself off.
), press
Cancel the calibration with
operation (5).
Make sure that the measuring tool and the laser receiver are
aligned correctly (see description above). Restart the calib-
ration.
If calibration fails again, have the measuring tool checked by
a Bosch customer service agent.

Z-axis calibration

A free measuring distance on firm ground in front of a 10 m
wall is required for the calibration. Fix a plumb line to the
wall.
by press-
Position the measuring tool on a firm, level surface. Switch
the measuring tool on and allow it to level in. Align the meas-
uring tool so that the laser beam is perpendicular to the wall
and cuts through the plumb line. Switch the measuring tool
off.
To start calibration mode, press and hold the slope but-
ton (14) and then also briefly press the on/off button (11).
The measuring tool is switched on. Allow the measuring tool
to level in.
by pressing the
slope button (14). Calibration of the Y-axis
continues.
This symbol will appear on the measuring
tool display if the Y-axis has been success-
fully calibrated. "YOK" will appear on the dis-
play of the laser receiver.
by pressing the
This symbol confirms that the X-axis and the
Y-axis have been successfully calibrated with
the levelling accuracy selected at the begin-
ning. End the calibration with
the slope button (14).
The relevant error message will ap-
pear in the measuring tool display if
calibration of the X‑axis or the Y‑axis
has not been successful. "ERR" will
appear on the display of the laser
receiver.
