Operation
Initial Operation
 Do not leave the switched-on measuring tool unattended and switch the mea-
suring tool off after use. Other persons could be blinded by the laser beam.
 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures 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 measuring tool to adjust to the ambient
temperature before putting it into operation. In case of extreme temperatures or
variations in temperature, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact to or falling down of the measuring tool. After severe exte-
rior effects to the measuring tool, it is recommended to carry out an accuracy
check (see "Accuracy Check of the Measuring Tool", page 33) each time before
continuing to work.
Switching On and Off
To switch on the measuring tool, briefly press the On/Off button 1 or the measuring
button 4. When switching on the measuring tool, the laser beam is not switched on.
To switch off the measuring tool, press the On/Off button 1 for a few seconds.
If none of the measuring tool buttons are pressed for approx. 5 minutes, the measur-
ing tool switches off automatically in order to extend the service life of the battery.
Measuring Procedure
Once switched on, the measuring tool is in the length measure-
ment function. You can set other measuring functions by re-
peatedly pressing the button 2 (see "Measuring Functions",
page 27).
After confirming the measurement function with the measuring
button 4, the laser beam is switched on.
After switching on, the rear edge of the measuring tool is preset as the reference level
for the measurement. To change the reference level, see "Selecting the Reference
Level", page 27.
With the reference level selected, place the measuring tool against the desired meas-
uring line (e.g. a wall).
To initiate the measurement, briefly press the measuring button 4. Then the laser
beam is switched off. To switch the laser beam on again, briefly press the measuring
button 4. To initiate a further measurement, briefly press the measuring button 4.
