Safety instructions
All instructions must be read and observed in order for
the measuring tool to function safely. The safeguards in-
tegrated into the measuring tool may be compromised if
the measuring tool is not used in accordance with these
instructions. Never make warning signs on the measur-
ing tool unrecognisable. SAVE THESE INSTRUCTIONS FOR FUTURE REF-
ERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN
TRANSFERRING IT TO A THIRD PARTY.
uWarning! If operating or adjustment devices other than those spe-
cified here are used or other procedures are carried out, this can lead
to dangerous exposure to radiation.
The measuring tool is delivered with a warning sign (marked in the illustra-
tion of the measuring tool on the graphics page with number (6)).

Laser Radiation
Do not stare into beam
Class 2 laser product
uIf the text on the warning label is not in your native language, cover it
with the label supplied, which is in your language, before initial com-
missioning.
Do not direct the laser beam at persons or animals and
do not look directly into the laser beam or at its reflec-
tion. Doing so could lead to blindless, or could cause acci-
dents or damage to the eyes.
uIf laser radiation hits your eye, you must close your eyes and immedi-
ately turn your head away from the beam.
uDo not use the laser goggles as protective goggles. The laser goggles
make the laser beam easier to see; they do not protect you against laser
radiation.
uDo not use the laser goggles as sunglasses or while driving. The laser
goggles do not provide full UV protection and impair your ability to see
colours.
uHave the measuring tool serviced only by a qualified specialist using
only original replacement parts. This will ensure that the safety of the
measuring tool is maintained.
uDo not let children use the laser measuring tool unsupervised. They
could accidentally dazzle someone.
uDo not use the measuring tool in explosive atmospheres which con-
tain flammable liquids, gases or dust. Sparks may be produced inside
the measuring tool, which can ignite dust or fumes.
uDo not make any modifications to the laser equipment.

A) The working range increases depending on how well the laser light is reflected
from the surface of the target (scattered, not reflective) and how bright the laser
point is relative to the ambient light intensity (interior spaces, twilight). In unfa-
vourable conditions, e.g. with extremely bright interior lighting or a poorly reflect-
ing surface, the measuring range may be reduced.
B) In unfavourable conditions, e.g. with extremely bright interior lighting, a poorly re-
flecting surface, or a room temperature that deviates significantly from 25 °C, the
maximum deviation can be up to ± 7 mm at 15 m. In favourable conditions, a devi-
ation influence of ± 0.05 mm/m needs to be taken into account.
C) non-conductive soiling only, whereby occasional temporary conductivity caused
by condensation is expected
The serial number (5) on the type plate is used to clearly identify your measuring tool.
Fitting
Inserting/Changing the Batteries
It is recommended that you use alkaline manganese batteries to operate the
measuring tool.
Push the locking mechanism (4) in the direction of the arrow to open the
battery compartment cover (3) and remove the battery compartment cover.
Insert the batteries. When inserting, pay attention to the correct polarity ac-
cording to the representation on the inside of the battery compartment.
When the battery symbol first appears on the display, measurements can
be made for approx. another 15 minutes. When the battery symbol flashes,
you have to replace the batteries because measurements are no longer pos-
sible.
Always replace all the batteries at the same time. Only use batteries from the
same manufacturer and which have the same capacity.
uTake the batteries out of the measuring tool when you are not using it
for a prolonged period of time. The batteries can corrode and self-dis-
charge during prolonged storage.

Operation
Start-Up
uNever leave the measuring tool unattended when switched on, and
ensure the measuring tool is switched off after use. Others may be
dazzled by the laser beam.
uProtect the measuring tool from moisture and direct sunlight.
uDo not expose the measuring tool to any extreme temperatures or
variations in temperature. For example, do not leave it in a car for ex-
tended periods of time. In case of large variations in temperature, allow
the measuring tool to adjust to the ambient temperature before putting it
into operation. The precision of the measuring tool may be compromised
if exposed to extreme temperatures or variations in temperature.
uAvoid subjecting the measuring tool to violent jolts and falls. Always
check the measuring tool before continuing work if it has been subjected
to severe external influences (see "Checking the Measuring Tool",
page14).
Switching On/Off
To switch on the measuring tool, press the on/off button (1). When the
measuring tool is switched on, the laser beam is switched on. The laser sym-
bol flashes on the display.
To switch off the measuring tool, press and hold the on/off button (1) for at
least three seconds.
If no button on the measuring tool is pressed for approx. 5 mins, the measur-
ing tool will automatically switch itself off to preserve battery life.
Measuring Process
A continuous measurement is performed after the measuring tool has been
switched on. Aim the laser beam at the target surface. The current measured
value (g) is shown on the bottom line of the display (see figure A). During
continuous measurement, the measuring tool can be moved relative to the
target and the current measured value (g) will be updated approx. every 0.5
seconds on the bottom line of the display (see figure B). You can, for ex-
ample, move a desired distance away from a wall while reading off the cur-
rent distance at all times. The laser symbol flashes on the display.
