Initial Operation

Protect the measuring tool against moisture.
Do not subject the measuring tool to extreme temperatures or
variations in temperature. As an example, do not leave it in ve-
hicles for longer periods. In case of large variations in tempera-
ture, allow the measuring tool to adjust to the ambient temper-
ature before putting it into operation. In case of extreme
temperatures or variations in temperature, the accuracy of the
measuring tool can be impaired.
Setting Up the Measuring Tool (see figure A)
Position the measuring tool at least 5 m away from the cross-line
laser. Switch on the pulsating function on the cross-line laser, and
select horizontal or vertical operation.
Note: Do not select cross-line operation, as otherwise faulty indi-
cations on the height of the laser beam can occur.
Position the measuring tool in such a manner that the laser beam
can reach the reception area 6. Align the measuring tool in such a
manner that the laser beam runs laterally through the reception
area (as shown in the figure).
Switching On and Off
A loud audio signal sounds when switching on the measuring
tool. Therefore, keep the measuring tool away from your ear
or other person when switching on. The loud audio signal can
cause hearing defects.
To switch on the measuring tool, press the On/Off button 2. All dis-
play indicators as well as all LEDs light up briefly and an audio sig-
nal sounds.
