A) The working range increases 
depending on how well the laser
light is reflected from the surface
of the target (scattered, not
reflective) and with increased
brightness of the laser point to the 
ambient light intensity (interior 
spaces, twilight). In...

INITIAL OPERATION
  Protect the rangefinder against    moisture and direct sun  
  irradiation.
  Do not expose the rangefinder    to extreme temperatures or 
  variations in temperature. 
Switching On and Off
To  switch on the rangefinder,
briefly press the On/Off button  14
or measuring button  10. When
switching on the rangefinder, the  laser beam is not switched  
on yet. 
To 
switch off the rangefinder, 
press and hold the On/Off/clear  
button  14for a few seconds.
To save the batteries, the...

When switching on the
rangefinder again,  “M”is
indicated in the display. 
Measuring Procedure
The rangefinder offers a variety 
of different measuring modes that
can be selected by pushing the 
corresponding mode button (see 
“Measuring Mode”). After
switching on, the rangefinder is in
the “length measurement mode”. 
Also, it is possible to select any of 
the four different reference points
for the measurement by pushing
the reference point button  1(see
“Selecting the Reference Point”).
After...

To select the reference point, 
push button 1repeatedly until the
required reference point is 
indicated in the display. Each
time after switching on, the rear
edge of the rangefinder is preset
as the reference point.
Changing the Unit of Measure
The unit of measure can be
changed any time for display of
the measured values, even for 
already measured or calculated 
values. 
For display of the current length 
measurement values, the units of 
measure shown above are 
available.

Area Measurement
For area measurements, push 
button  5until the indicator for
area measurement
appears in the display. 
Afterwards, measure the length 
and the width, one after another,
in the same manner as a length
measurement. The laser beam
remains switched on between
both measurements. 
After taking the second  
measurement, the area is
automatically calculated and 
displayed. The last individual 
measured value is indicated at 
the bottom in the display, while
the final result is shown at...

To start the measurement, briefly 
push the measuring button 10.
Move the laser back and forth
over the requested target (e.g.,
the room ceiling for determining
the plumb line) in such a manner
that the reference point of the
measurement (e.g., the tip of the
extension pin  15) always 
remains at the same location. 
During the measurement, the 
current length measurement
value is indicated at the bottom of
the display.
The minimum value is indicated
at the top right in the display. It is

target surface is available as a 
reflector. Correct results are
achieved only when the laser
beam and the sought distance
form an exact right angle (90°)
(Pythagorean Theorem). 
In the illustrated example, the 
length Bis to be determined. For
this purpose,  Aand  Cmust be
measured.  Aand  Bmust form a
right angle. 
For indirect length  
measurements, push button  11
until the indicator for indirect
length measurement       appears
in the display.
Measure the distance  Aas for a
length measurement....

at the bottom in the display, while 
the surface is indicated at the top.
The laser remains switched on. 
Now, measure length B
2 of the
second wall. The individual  
measuring value indicated at the
bottom of the display is added to
length  B
1 and the sum of both
lengths is multiplied with the
stored length  A. The total surface
value is indicated at the top in 
the display.
In this manner, you can measure
any number of further lengthsB X, which are added and 
multiplied with length  A.

all measuring functions. Pushing 
the button repeatedly deletes the
individual measured values in
reverse order. 
In the multi-surface area 
measurement mode, pushing
button 14the first time deletes
the last individually measured
value; pushing the button a
second time deletes all 
lengths  B
X.
Memory Modes
When switching off the 
Rangefinder, the value in the
memory is retained. 
In the multi-surface area measur- 
ement mode, the total surface
value can be stored; in the
minimum and maximum...

Displaying the Stored Value 
Push the memory retrieve button 2in order to display the value
stored in the memory.  “M=”is 
indicated in the display. When the
memory contents  “M=”is 
indicated in the display, it can be
doubled by pushing the memory
add button  3or set to zero by
pushing the memory subtract
button  12.
The memorized values can only
be displayed in decimal feet 
or meters. Deleting the Memory
To delete the memory contents,
first push the memory retrieve
button  2, so that  “M=”is...
