10 m
battery lid 9 in the direction of the arrow and re-
move the battery lid. Insert the supplied batter-
± 0.3 mm/m
ies. When inserting, pay attention to the correct
polarity according to the representation on the
± 4°
inside of the battery compartment.
When the battery indication 3 flashes red, the
<4 s
batteries must be replaced.

Initial Operation

12 h
Protect the measuring tool against mois-
ture and direct sun irradiation.
60 min
Do not subject the measuring tool to ex-
treme temperatures or variations in tem-
0.45 kg
perature. As an example, do not leave it in
118 x 57 x 89 mm
vehicles for longer periods. In case of large
IP 54
variations in temperature, allow the measur-
(dust and splash ing tool to adjust to the ambient temperature
water protected) 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.
