Assembly

Charging the Batteries of the Measuring Tool and
Laser Receiver (see figures A– B)
Do not use a different battery charger. The battery
charger provided is matched to the lithium-ion battery in-
stalled in your measuring tool.
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 batter-
ies, 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",
page38) 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:
– Press the sleep mode button 21 until the audio
signal sounds.
The battery charge-control indicators 29 and 30
are displayed.
The display illumination switches off again after 5 s.
