Basic settings
Switching the display illumination on/off
Briefly press the Illumination key (9) to switch the display
illumination on/off.
Switching the acoustic signal on/off
Press the Signal tone on/off key for a long time to switch the
acoustic signal on/off.
Aborting the measurement and deleting the display
Briefly press the Delete button (8) to abort the current
measurement or to delete the displayed measured values.
Setting the reference value
The device always measures the total distance beginning with the
reference point. This means that if the rear end of the device is
set as reference point, the length of the device will be part of the
measurement. By default the reference point is set to the rear of
the device. You can, however, also relocate the reference point to
the front part of the device. Proceed as follows:
• Press the Reference key (9) for a long time to relocate the
reference point to the front end of the device.
=> An acoustic signal can be perceived, whenever the
reference point is relocated. Additionally, the indication
Reference value front (26) appears.
When switching the device off and then on again, the reference
value will automatically be relocated to the rear end of the device.
Changing the units
• Press the Unit key (10) for a long time to switch between the
units for the measured values. Available units are ft, in.
and m.
• Briefly press the Unit key (10) to switch between the area

units (ft , m ) and the volume units (ft
Displaying the inclination
• Press the Inclination key (7) for a long time.
– The inclination of the device will be indicated in the
Inclination display (21).
Calling up a measured value in the device history
The device automatically saves the last 10 measured values. The
saved measured values can be called up as follows:
1. Press the Save button (6) for a long time to call up the history.
2. Briefly press the Minus key (6) or the Plus key (11) to
navigate through the history and call up the saved measured
values.
3. You can return to the normal measuring menu by briefly
pressing the Delete button (8) or the Measurement button (5).

Risk from laser radiation!
Class 2 laser radiation.
Lasers of class 2 only radiate in the visible range and
during continuous wave operation (lasting beam) no more
than 1 milliwatt (mW) of output will be emitted. Looking
directly into the laser beam for a longer period of time
(more than 0.25 seconds) can cause damage to the
retina.
Avoid looking directly into the laser beam. Never look into
the laser beam using optical aides. Do not suppress the
winking reflex when looking into the laser beam
unintentionally. Never point the laser beam at people or
animals.
