– The measuring tool is reset to factory settings.

Measuring Tool Software Update

If there is a software update available for the measuring tool, a notification will appear in

theBosch Levelling Remote App. To install the update, follow the instructions in the

app.

During the update, the Bluetooth®button(2) will flash quickly. All of the other buttons

will be deactivated and the laser lines will be switched off until the update has been suc-

cessfully installed.

Accuracy Check of the Measuring Tool

Influences on Accuracy

The largest influence is exerted by the ambient temperature. In particular, temperature

differences that occur from the ground upwards can refract the laser beam.

In order to minimise thermal influences resulting from heat rising from the floor, it is re-

commended that you use the measuring tool on a tripod. In addition, position the meas-

uring tool in the centre of the work surface, wherever this is possible.

In addition to external influences, device-specific influences (e.g. falls or heavy impacts)

can also lead to deviations. For this reason, check the levelling accuracy each time be-

fore beginning work.

First check the height accuracy and levelling accuracy of the horizontal laser line, then

the levelling accuracy of the vertical laser line and the plumb accuracy.

Should the measuring tool exceed the maximum deviation during one of the tests, please

have it repaired by a Bosch after-sales service.

Checking the Height Accuracy of the Horizontal Line

For this check, you will need a free measuring distance of 5m on firm ground between

two walls (designated A andB).

– Mount the measuring tool close to wallA on a tripod, or place it on a firm, level sur-

face. Switch on the measuring tool and select cross-line operation.

– Aim the laser at the closer wall A and al-

low the measuring tool to level in. Mark

the middle of the point at which the laser

lines cross on the wall (pointI).
