Alkali-manganesebatteriesarerecommended for the
measuringtool.
Toopen the battery lid , pressonthelatch andfoldthe
batterylidup. Insert thebatteries.Wheninserting, payat-
tentiontothecorrect polarityaccordingtotherepresen-
tationontheinsideof thebattery compartment.
Whenthebattery indication flashes, thebatteriesare
weak. Whenthebattery indicationflashesfor the first
time, themeasuringtool can still be operatedfor approx.
2 h.
Whenthe battery indication lightsup constantly, mea-
suringis no longer possible. The measuringtool automat-
icallyswitchesoff after ashort time.
Alwaysreplaceall batteriesat thesametime. Only use
batteriesfromone brand and with theidentical capacity.
Whenstor-
ingfor extended periods, thebatteriescancorrode

When theOn/Off button ispressed asecondtime, the
measuringtool switchesover from3-lineoperation to
2-lineoperation: Onlythe0°and the90°laser lines are

Toactivate the automatic switch-off, switchthe measur-
ingtool off and switchit onagainby pressingbrieflythe
On/Off button . Aftertheswitchingon, thelaser linesdo
not flash.
The ambient temperature has the greatest influence. Es-
peciallytemperaturedifferencesoccurringfromthe
groundupward can divert thelaser beam.
Therefore, positionthemeasuringtoolasnear aspossible
totheworksurfaceandfixit with theundersideasparallel
aspossibleto theworksurface.
In additiontoexternal influences, device-specificinflu-
ences(e.g. fallsor heavy impacts) canalsolead todevia-
tions. For thisreason, check the levellingaccuracyeach
