Assembly
Inserting/Replacing the Battery
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 bat-
teries. When inserting, pay attention to the cor-
rect 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 batteries from one brand and with the
identical capacity.
f
Remove the batteries from the measuring
tool when not using it for extended periods.
When storing for extended periods, the bat-
teries can corrode and discharge themselves.
Operation
Initial Operation
f Protect the measuring tool against mois-
ture and direct sun irradiation.
f Do not subject the measuring tool to ex-
treme temperatures or variations in tem-
perature. As an example, do not leave it in
vehicles for longer periods. In case of large
variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature
before putting it into operation. In case of
extreme temperatures or variations in tem-
perature, the accuracy of the measuring tool
can be impaired.
f Avoid heavy impact or falling of the measur-
ing tool. After heavy exterior impact on the
measuring tool, an accuracy check should
always be carried out before continuing to
work (see “Levelling Accuracy”).
f Switch the measuring tool off during trans-
port. When switching off, the levelling unit,
which can be damaged in case of intense
movement, is locked.
