Troubleshooting – Causes and Corrective Measures
The measuring tool monitors the proper function for each measurement. When a de-
fect is detected, all indicators on the display flash. In this case, or when the corrective
measures listed above cannot correct the error, have your dealer forward the meas-
uring tool to an authorised Bosch after-sales service.

The measuring tool is outside the
operating temperature range of –10 °C
to +45 °C.
Wait until the measuring tool has
reached the operating temperature

The target surface reflects too intensely
(e.g. a mirror) or insufficiently (e.g. black
fabric), or the ambient light is too bright.
Work with the laser target plate 13 (ac-
cessory)
The laser beam outlet 12 or the reception
lens 11 are misted up (e.g. due to a rapid
temperature change).
Wipe the laser beam outlet 12 and/or
the reception lens 11 dry using a soft
cloth
Measuring result not plausible
The target surface does not reflect
correctly (e.g. water, glass).
Cover off the target surface
The laser beam outlet 12 or the reception
lens 11 are covered.
Make sure that the laser beam outlet 12
or the reception lens 11 are unobstruct-
ed
Obstruction in path of laser beam Laser point must be completely on tar-
get surface.
