Battery Charging
– Clean soiled charger contacts using a dry cloth.
– Plug the charge connector 51 into the socket provided on
the charger 49.
The measuring tool can be recharged independently of the la-
ser receiver, however the laser receiver can only be re-
charged together with the measuring tool.
Measuring tool (seefigureA):
– Open the cover 11 of the charge socket 14.
– Plug the power plug 52 of the power supply into the socket
outlet and the charge connector 50 into the charge socket
14.
Laser Receiver (seefigureB):
– Slide the laser receiver into the charging/storage station 6.
– Open the cover 11 of the charge socket 14.
– Plug the power plug 52 of the power supply into the socket
outlet and the charge connector 50 into the charge socket
14.
The measuring tool and the laser receiver will switch off after
charging.
Disconnect the battery charger from the mains supply when
not using it for longer periods.
Protect the battery charger against moisture!
Recommendations for Optimal Handling of the Battery
Store the measuring tool and the laser receiver only within the
permitted temperature range, see “Technical Data”. As an ex-
ample, do not leave them in the car in summer.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Operation
Initial Operation
Keep the measuring tool and the laser receiver dry and
protect them from direct sunlight.
Do not expose the measuring tool and the laser receiv-
er to extreme temperatures or variations in tempera-
ture. For example, do not leave them in a car for extended
periods of time. In case of large variations in temperature,
allow the measuring tool and the laser receiver to adjust to
the ambient temperature before putting them into opera-
tion. The precision of the measuring tool and the laser re-
ceiver may be compromised if exposed to extreme temper-
atures or variations in temperature.
Avoid heavy impact to or falling down of the measuring
tool. After severe exterior effects to the measuring tool, it
is recommended to carry out an accuracy check (see “Ac-
curacy Check of the Measuring Tool”, page43) each time
before continuing to work.
Setting Up the Measuring Tool
– Position the measuring tool on a stable surface in the hori-
zontal or vertical position, mount it to a tripod or to the wall
mount 59 with alignment unit.
Due to the high levelling accuracy, the measuring tool reacts
sensitively to ground vibrations and position changes. There-
fore, pay attention that the position of the measuring tool is
stable in order to avoid operational interruptions due to re-
levelling.
Operating the Measuring Tool (see figure C)
The measuring tool is operated using the buttons on the laser
receiver. Operation can be carried out either directly at the
measuring tool (laser receiver docked in charging/storage
station 6) or via RF communication (laser receiver acts as a re-
mote control).
Operating States
The system consisting of measuring tool and laser receiver
knows 3 operating states:
– Operating
All functions of the measuring tool and laser receiver are
activated.
See “Switching On”, page38.
– Sleep mode
To save energy, most of the functions of the measuring tool
are deactivated for 2 h maximum.
The theft alarm system and the anti-drift system are still ac-
tivated.
All settings (audio signal/volume, measuring accuracy,
slope, etc.) are saved.
See “Sleep Mode”, page38.
– Switched off
All functions of the measuring tool and laser receiver are
deactivated.
See “Switching Off”, page38, and “Automatic Shutdown”,
page38.
Switching On and Off
Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from
a large distance.
Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
Note: Before using the measuring tool, you should always
perform an accuracy check (see “Accuracy Check of the
Measuring Tool”, page43).
