Operation
Initial Operation
 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.
Setting Up the Measuring Tool (see figure A)
Set up the measuring tool at least 5 m away from the line laser. Switch on the pulse
function of the line laser. Select an operating mode on the line laser where either only
one horizontal or vertical laser plane is generated.
Note: Do not select an operating mode with both horizontal and vertical laser plane
(cross-line operation), as otherwise faulty height indications of the laser beam may
occur.
Position the measuring tool in such a manner that the laser beam can reach the recep-
tion area 5. Align the measuring tool in such a manner that the laser beam runs later-
ally 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 persons when switching
on. The loud audio signal can cause hearing defects.
To switch on the measuring tool, press the On/Off button 3. All display indicators as
well as all LEDs light up briefly and an audio signal sounds.
After switching on the measuring tool, a medium volume and the "fine" accuracy are
always set.
To switch off the measuring tool, press the On/Off button 3 again. All LEDs and all
display indicators light up briefly before the tool switches off, and an audio signal
sounds.
If no button on the measuring tool is pressed for approx. 20 min and no laser beam
reaches the reception area for 5 20 min, then the measuring tool switches off auto-
matically to save the battery. The switching off is indicated by all LEDs and all display
indicators lighting up briefly, and an audio signal sounds.
