Error Message
The measuring tool monitors correct operation in
every measurement. If a defect is detected, the
display will indicate only the symbol shown op-
posite. In this case, or if you are unable to rectify
an error using the corrective measures above,
send the measuring tool to the Bosch after-sales service via
your dealer.
Troubleshooting
Temperature warning
Temperature warning flashes, measurement not possible
Cause: Measuring tool is outside the operating temperature of
–10 °C to +45 °C (in the continuous measurement function up
to +40 °C)
Corrective measure: Wait until the measuring tool reaches the
operating temperature
Battery indicator
Battery indicator dwindling
Cause: Battery voltage is dropping (measurement still pos-
sible)
Corrective measure: Change the batteries.
Battery indicator empty, measurement not possible
Cause: Battery voltage too low
Corrective measure: Change the batteries.
"ERROR" in the Display
"ERROR" indicator in the display
Cause: Addition/subtraction of measured values with different
units of measurement
Corrective measure: Add/subtract only measured values with
the same units of measurement
Cause: Angle between laser beam and target is too sharp
Corrective measure: Increase the angle between the laser
beam and target
Cause: Target surface is reflecting too strongly (e.g. mirror) or
too weakly (e.g. black material), or ambient light is too strong
Corrective measure: Use a laser target plate (accessory)
Cause: Calculated value is larger than 1 999 999 or smaller
than -999 999 m/m²/m³
Corrective measure: Split the calculation into intermediate
steps
Cause: The laser beam output (19) and/or the reception
lens (18) and/or the camera (20) are fogged up (e.g. due to a
rapid temperature change)
1 609 92A 7P4 | (22.07.2022)
Corrective measure: Rub the laser beam output (19) and/or
the reception lens (18) and/or the camera (20) dry with a soft
cloth
Measurement Result
Measurement result implausible
Cause: Target surface is not reflecting clearly (e.g. water,
glass)
Corrective measure: Cover the target surface
Cause: The laser beam output (19) and/or the reception
lens (18) and/or the camera (20) are concealed
Corrective measure: Always keep the laser beam output (19),
the reception lens (18) and the camera (20) clear
Cause: Obstacle in the course of the laser beam
Corrective measure: Ensure that the laser point is fully on the
target surface
Cause: Incorrect reference level set
Corrective measure: Select the reference level appropriate to
the measurement
Bluetooth®
Bluetooth® cannot be activated
Cause: Non-rechargeable batteries or rechargeable batteries
are too weak
Corrective measure: Change the non-rechargeable batteries
or rechargeable batteries
No Bluetooth® connection
Cause: Disruption of the Bluetooth® connection
Corrective measure:
– Check whether Bluetooth® is activated (both on the measur-
ing tool and on your mobile device)
– Switch Bluetooth® off and on again (both on the measuring
tool and on your mobile device)
– Check the application on your mobile device
– Check your mobile device for overload
– Decrease the distance between the measuring tool and your
mobile device
– Avoid obstacles (e.g. reinforced concrete, metal doors)
between the measuring tool and your mobile device; keep
your distance from electromagnetic sources of interference
(e.g. Wi-Fi transmitters)
Display Unchanged
The display remains unchanged or the measuring tool
reacts unexpectedly to pressing the measuring button/
buttons
Cause: Software error
Corrective measure: Remove the non-rechargeable batteries/
rechargeable batteries and restart the measuring tool after re-
insertion
