Assembly
Inserting/Replacing the Batteries
Use only alkali-manganese batteries.
To open the battery lid
8
, press the latch of the battery lid
11
in the direction of the arrow and remove the battery lid. Insert
the supplied batteries. When inserting, pay attention to the
correct polarity according to the representation on the inside
of the battery compartment.
When the battery indication
5
flashes red, the batteries must
be replaced.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
Remove the batteries from the measuring tool when
not using it for extended periods.
When storing for ex-
tended periods, the batteries can corrode and self-dis-
charge.
Operation
Initial Operation
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature.
As an example, do
not leave it in vehicles for a long time. In case of large vari-
ations 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 tempera-
ture, the accuracy of the measuring tool can be impaired.
Avoid heavy impact or falling of the measuring tool.
Af-
ter heavy exterior impact on the measuring tool, an accura-
cy check should always be carried out before continuing to
work (see “Levelling Accuracy”).
Switch the measuring tool off during transport.
When
switching off, the levelling unit, which can be damaged in
case of intense movement, is locked.
Switching On and Off
To
switch on
the measuring tool, slide the On/Off switch
7
to
the
“
on”
position (when working without automatic level-
ling) or to the
“
on”
position (when working with automat-
ic levelling). Immediately after switching on, the measuring
tool sends laser beams out of the exit openings
1
.
Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from
a large distance.
To
switch off
the measuring tool, slide the On/Off switch
7
to
the
“off”
position. When switching off, the levelling unit is
locked.
Deactivating the Automatic Shut-off
The measuring tool switches off automatically after an operat-
ing duration of 30 minutes. To deactivate the automatic
switch-off, keep the operating mode button
4
pressed for 3 s
while switching on the measuring tool. When the automatic
switch-off is deactivated, the laser lines briefly flash after 3 s.
Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use.
Other
persons could be blinded by the laser beam.
To activate the automatic shut-off, switch the measuring tool
off and then on again (without the operating mode button
4
pushed).
