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 9. 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 2. An audio signal will
sound and all LEDs will light up briefly.
To switch off the measuring tool, press the On/Off button 2 again. An audio signal
sounds three times and all LEDs light up briefly before the tool switches off. The pow-
er indicator 3 extinguishes.
When no pushbutton on the measuring tool is pressed for approx. 20 minutes and
when no laser beam is impinged upon the reception area 9 for 20 minutes, the meas-
uring tool switches off automatically to save the batteries.
Selecting the Setting of the Centre Indicator
With button 1, you can specify the accuracy with which the position of the laser beam
is indicated as centred on the reception area:
– "Coarse" adjustment (the direction LEDs 8 and 6 flash).
– "Fine adjustment" (the centre-indication LED 7 flashes),
After switching on the measuring tool, the "fine" accuracy is always set.
