Troubleshooting – Causes and Corrective Measures
Cause
Temperature warning indicator (g) flashing; measurement not possible
The measuring tool is outside the
operating temperature range of –10 °C
to +45 °C.
"Error" indication in the display
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 8 or the reception
lens 7 are misted up (e.g. due to a rapid
temperature change).
The calculated auto-sum is greater than
99999 m.
Measuring result not plausible
The target surface does not reflect
correctly (e.g. water, glass).
The laser beam outlet 8 or the reception
lens 7 are covered.
Obstruction in path of laser beam
The indication remains unchanged or the measuring tool reacts unexpectedly
after pressing a button
Software error
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.

(accessory)
Wipe the laser beam outlet 8 and/or the
reception lens 7 dry using a soft cloth
Divide calculation into intermediate steps
Cover off the target surface
Make sure that the laser beam outlet 8 or
the reception lens 7 are unobstructed
Laser point must be completely on target
surface.
Remove the batteries and start the
measuring tool again after reinserting
them.
