Cause
Battery indicator empty, measurement not possible
Battery voltage too low
"Error" and "––––" indication in display
The angle between the laser beam and
the target is too acute.
The target surface reflects too intensely
(e.g. a mirror) or insufficiently (e.g. black
fabric), or the ambient light is too bright.
The laser beam outlet 13 or the reception
lens 12 are misted up (e.g. due to a rapid
temperature change).
Calculated value is greater than 999 999
or smaller than –999 999 m/m
Unreliable measuring result
The target surface does not reflect cor-
rectly (e.g. water, glass).
The laser beam outlet 13 or the reception
lens 12 are covered.
Measuring result not plausible
Wrong reference level set
Obstruction in path of laser beam
The measuring tool monitors the correct operation in each measure-
ment. If a defect is detected, the display will show only the adjacent
symbol. In this case, or when the above mentioned corrective meas-
ures cannot correct an error, have the measuring tool checked by an
after-sales service agent for Bosch power tools.
Accuracy Check of the Measuring Tool
The accuracy of the measuring tool can be checked as follows:
– Select a permanently unchangeable measuring section with a length of approx. 3
to 10 metres; its length must be precisely known (e.g. the width of a room or a
door opening). The measuring distance must be indoors; the target surface for the
measurement must be smooth and reflect well.

Corrective Measure
Replace batteries/rechargeable batteries
Enlarge the angle between the laser beam
and the target
Work with the laser target plate 16 (ac-
cessory)
Wipe the laser beam outlet 13 and/or the
reception lens 12 dry using a soft cloth
Divide calculation into intermediate steps

/m .
Cover off the target surface
Make sure that the laser beam outlet 13
or the reception lens 12 are unobstructed
Select reference level that corresponds
to measurement
Laser point must be completely on target
surface.
