Assembly

Inserting/Replacing the Battery

Use only alkali-manganese batteries.
To open the battery lid 10, press the latch of the
battery lid 9 in the direction of the arrow and re-
move the battery lid. Insert the supplied batter-
ies. When inserting, pay attention to the correct
polarity according to the representation on the
inside of the battery compartment.
When the battery indication 3 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.
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

Protect the measuring tool against mois-
ture and direct sun irradiation.
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.
Avoid heavy impact or falling of the measur-
ing tool. After heavy exterior impact on the
measuring tool, an accuracy check should al-
ways be carried out before continuing to
work (see "Levelling Accuracy").
Switch the measuring tool off during trans-
port or when carrying it by the carrying
strap 17. When switching off, the levelling
unit, which can be damaged in case of in-
tense movement, is locked.
