Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
Aim the laser beam at the target surface. Briefly
press the measuring button 7 again to initate
the measurement.
When the laser beam is switched on perma-
nently, the measurement already starts after the
first actuation of the measuring button 7. In con-
tinuous measurement mode, the measurement
starts immediately upon switching on.
Typically, the measured value appears after
0.5 and latest after 4 seconds. The duration of
the measurement depends on the distance, the
light conditions and the reflection properties of
the target surface. The end of the measurement
is indicated by a signal tone. The laser beam is
switched off automatically upon completion of
the measurement.
When no measurement has taken place approx.
20 seconds after sighting, the laser beam is
switched off automatically to save the batteries.
Selecting the Reference Level
(see figures A – E)
For measuring, you can select between four
different reference planes:
– The rear edge of the measuring tool or the
front edge of the laterally folded-out posi-
tioning pin 18 (e.g. when measuring onward
from outer corners),
– The tip of the folded-out positioning pin 18
(e.g. when measuring from a corner),
– The front measuring-tool edge (e.g. when
measuring onward from a table edge),
– The thread 21 (e.g. for tripod measurements).
To select the reference level, press button 8
until the requested reference level is indicated
on the display. Each time after switching on the
measuring tool, the rear end of the measuring
tool is preset as the reference level.
Subsequent changing of the reference level for
measurements that have already been carried
out (e.g. when indicating measuring values in
the measured-value list) is not possible.
Bosch Power Tools
Continuous Laser Beam
If required, the measuring tool can also be
switched to the continuous laser beam mode.
For this, push the button for continuous laser
beam 2. "LASER" lights up continuously in the
display.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
In this setting, the laser beam also remains
switched on between measurements; for meas-
uring, it is only required to press the measuring
button 7 once.
To switch off the continuous laser beam, press
button 2 again or switch the measuring tool off.
Switching off the continuous laser beam during
a measurement automatically ends the measure-
ment.
Display Illumination
The display illumination is switched on and off
by pressing button 11. When no button is
pressed 10 s after switching on the display illu-
mination, it is switched off to save the batteries.
Audio Signal
To switch the audio signal on
and off, press the function-
mode button 3 until the "au-
dio-signal adjustment" indica-
tion appears on the display.
Select the required setting by
pressing the plus button 6 or
the minus button 12.
The selected audio-signal adjustment is retained
when switching the measuring tool off and on.
