Assembly
Charging the Batteries of the Measuring Tool and
Laser Receiver (see figures A– B)
f Do not use a different battery charger. The battery
charger provided is matched to the lithium-ion battery in-
stalled in your measuring tool.
f Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the battery charger.
The measuring tool and laser receiv-
er must be charged only in dry in-
door areas. The charging cable is not permitted for charging
outdoors or in moist environments.
Note: The batteries of the measuring tool and laser receiver
are supplied partially charged. To ensure full capacity of the
batteries, completely charge the batteries before the first
use.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
Charge-control Indicator
The measuring tool must be switched on (see “Switching On”,
page 38) to display the battery charge status of the measur-
ing tool and laser receiver.
If the measuring tool is switched off and the laser receiver is in
the charging/storage station 6, the battery charge status can
be displayed as follows:
The display illumination switches off again after 5 s.
