cept for deviations pursuant to Laser Notice No. 50,
dated June 24, 2007. This can lead to persons being
blinded.
DO NOT stare directly at the laser beam or project
the laser beam directly into the eyes of others. Seri-
ous eye injury could result.
DO NOT place the laser measure in a position that
may cause anyone to stare into the laser beam inten-
tionally or unintentionally. Serious eye injury could
result.
DO NOT operate the laser measure around children
or allow children to operate the laser measure. Seri-
ous eye injury could result.
ALWAYS: Make sure that any bystanders in the vicin-
ity of use are made aware of the dangers of looking
directly into the laser measure.
Never aim the beam at a workpiece with a reflective
surface. Bright shiny reflective sheet steel or similar
reflective surfaces are not recommended for laser
use. Reflective surfaces could direct the beam back
towards the operator.
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
DO NOT use any optical tools such as, but not limited
to, telescopes or transits to view the laser beam. Se-
rious eye injury could result.
DO NOT leave the laser measure “ON” unattended in
any operation mode. ALWAYS turn the laser measure
“OFF” when not in use. Leaving the laser measure
“ON” increases the risk of someone inadvertently star-
ing into the laser beam.
DO NOT operate the laser measure in combustible
areas such as in the presence of flammable liquids,
gases or dust.
Do not use the laser viewing glasses as safety gog-
gles. The laser viewing glasses are used for improved
visualization of the laser beam, but they do not protect
against laser radiation.

Do not use the laser viewing glasses as sun glasses
or in traffic. The laser viewing glasses do not afford
complete UV protection and reduce color perception.
ALWAYS position the laser measure securely. Dam-
age to the laser measure and/or serious injury to the
user could result if the laser measure falls.
Take care to recognize the accuracy and range of the
laser measure. Measurement may not be accurate if
used beyond the rated range of the laser measure.
DO NOT remove or deface any warning or caution
labels. Removing labels increases the risk of exposure
to laser radiation.
Electrical safety
Batteries can explode or leak, cause injury or fire. To
reduce this risk, always follow all instructions and
warnings on the battery label and package.
DO NOT short any battery terminals.
DO NOT charge alkaline batteries.

AFor measurements from the rear measuring tool edge, weak
backlighting and 25 ºC operating temperature are applicable for
high reflectivity of the target (e.g. a white-painted wall). In ad-
dition, a deviation influence of ±0.05 mm/m must be taken into
account.
BIn favorable conditions, a deviation influence of ±3/500 in/ft
(±0.05 mm/m) must be taken into account. In unfavorable con-
ditions, e.g., with extreme illumination, badly reflecting surface
or the room temperature deviating heavily from 77 °F (25 °C),
the maximum deviation can be up to ±3/25 in (±3.0 mm). Addi-
tionally, a deviation influence of ±9/500 in/ft (0.15 mm/m) must
be taken into account.
C Digital bubble level is intended for indication of device angle. It is
not for digital measuring or to be used to adjust the laser line.
DIn the real time measuring function, the maximum operating
temperature is 104 °F (40 °C).
EShut-off after approximately 5 minutes in the real time measur-
ing function.
FBattery compartment not included.
The laser measure can be clearly identified with the
serial number 11 on the type plate.
Intended Use
The laser measure is intended for measuring distanc-
es, lengths, heights and clearances. The laser measure
is suitable for measuring indoors.

Assembly
Inserting/Replacing the Batteries
Using alkali-manganese or rechargeable batteries is
recommended for operation of the measuring tool.
With 1.2V rechargeable batteries fewer measurements
could be possible than with 1.5V batteries.
To open the battery lid 9, press the latch 10 and re-
move the battery lid. Insert the batteries. When insert-
ing, pay attention to the correct polarity according to
the representation on the inside of the battery com-
partment.
When the empty battery symbol first appears on the
display, then approximately 100 measurements are
still possible. When the battery symbol is empty and
red flashing, measurements are no longer possible.
Replace the batteries.
Always replace all batteries at the same time. Only
use batteries from one brand and with identical ca-
pacity.
Remove the batteries from the laser measure when
not using it for extended periods. When storing for
extended periods, the batteries can corrode and dis-
charge themselves.

Operation
Do not leave the switched-on laser
measure unattended and switch
the laser measure off after use. Other persons could
be blinded by the laser beam.
Protect the laser measure against moisture and di-
rect sun light.
Do not subject the laser measure to extreme temper-
atures or variations in temperature. As an example,
do not leave it in vehicles for a long time. In case of
large variations in temperature, allow the laser mea-
sure to adjust to the ambient temperature before put-
ting it into operation. In case of extreme temperatures
or variations in temperature, the accuracy of the laser
measure can be impaired.
Avoid heavy impact to or falling down of the laser
measure. After severe exterior effects to the laser
measure, it is recommended to carry out an accuracy
check (see “Accuracy Check of the Distance Measure-
ment”, page 25) each time before continuing to work.
Switching On and Off
– To switch on the laser measure and the laser, press
the measure button 2[ ] or clear/ on/off button
5[ ].
– To switch off the laser measure press and hold
clear/ on/off button 5[ ].
The values in the memory and the device settings are
retained when you switch the laser measure off.
Do not point the laser beam at
persons or animals and do not
look into the laser beam yourself, not even from a
long distance.
Measuring Procedure
Once switched on, the laser measure is in the real
time measuring function. The laser is automatically
activated and the laser measure is measuring. You can
set other measuring functions by pressing the function

button 7[Func] and using the plus button 3[ ] and
minus button 8[ ] to scroll through the measuring
functions. (see Measuring Functions, page 17)
After switching on, the rear edge of the laser measure
is preset as the reference point for the measurement.
To change the reference point (see Selecting the Ref-
erence Point, below).
Place the laser measure against the desired starting
point of the measurement (e.g. wall) and aim at the
surface you wish to measure to.
Note: The measured value typically appears within 0.5
seconds and no more than 4.25 seconds. The dura-
tion of the measurement depends on the distance, the
lighting conditions and the reflective properties of the
target surface.
Selecting the Reference Point
(see figure A on page 4)
For the measurement, you can select between three
different reference points:
- The rear edge of the laser measure (when the rear
edge of the laser measure is up against the wall
and you want to take a measurement from the wall
to another object)
- The front edge of the laser measure (when the la-
ser measure is resting on a table and you want to
measure from the edge of table to another object)
- The tripod thread of the laser measure (when at-
tached to a tripod)
To select between the three reference points, press
the measuring reference button 4. Cycle through the
desired reference measuring point options by press-
ing plus button 3[ ] or minus button 8[ ]. Press the
measure button 2[ ] to make your selection. If the
laser measure is turned off and then turned back on,
the reference point will reset to the rear edge of the
laser measure.

Indirect Measurement
Indirect Height
For indirect measurement, three mea-
suring modes are available. Each mea-
suring mode can be used for determin-
ing distances.
The indirect measurement is used
to measure distances that cannot be
measured directly because an obstacle
is obstructing the laser beam or no tar-
get surface is available as a reflector.
Note: Indirect measurement is always less accurate
than length measurement or real time measurement.
Depending on the application, greater measuring er-
rors are possible than with length measurement or real
time measurement. To improve the measuring accura-
cy, we recommend using a tripod (accessory).
