Battery Charging

– Clean soiled charger contacts using a dry cloth.
– Plug the charge connector 51 into the socket provided on
The measuring tool can be recharged independently of the la-
ser receiver, but the laser receiver can only be recharged to-
gether with the measuring tool. The measuring tool and the la-
ser receiver cannot be used during the charging process.
Measuring tool (see figure A):
– Open the cover 11 of the charge socket 14.
– Plug the power plug 52 of the power supply into the socket
Laser Receiver (see figure B):
– 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

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.

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.

is recommended to carry out an accuracy check (see "Ac-
curacy Check of the Measuring Tool", page 43) each time
before continuing to work.

Setting Up the Measuring Tool

Horizontal mode
(GRL 500 H/
GRL 500 HV)
Vertical mode
(GRL 500 HV)
– 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", page 38.
– 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", page 38.
– Switched off
All functions of the measuring tool and laser receiver are
deactivated.
See "Switching Off", page 38, and "Automatic Shutdown",
page 38.

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", page 43).
