Assembly
Power Supply
The measuring tool can be used either with commercially avail-
able batteries/rechargeable batteries, which are inserted in
battery compartment
16 , or with the CST/berger battery pack
18 .
Operation with Batteries/Rechargeable Batteries
Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
– To insert the batteries/rechargeable batteries, loosen nut 19
and remove the battery compartment 16 .
When inserting the batteries/rechargeable batteries, pay atten-
tion to the correct polarity according to the representation on
the inside of the battery compartment.
Always replace all batteries/rechargeable batteries at the same
time. Do not use different brands or types of batteries/re-
chargeable batteries together.
– Mount the battery compartment 16 again. Pay attention that
the nose of the battery compartment engages in the corre-
sponding recess in the housing (see illustration on the graph-
ic pages). Firmly tighten the battery compartment with nut
19 .

Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargeable
batteries can corrode and self-discharge.
Operation with Battery Pack
Charge the battery pack 18 before using for the first time. The
battery pack can only be charged with the battery charger 31 in-
tended for it.
– Insert the charge plug 32 of the battery charger into the
socket connector 17 of the battery pack. Connect the bat-
tery charger to the mains supply. Charging the empty battery
pack takes approx. 14 h.
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 charg-
ing/discharging cycles.
Do not charge the battery pack 18 each time after using, other-
wise its capacity will be reduced. Charge the battery pack only
when the charge-control indicator
6 flashes or lights up contin-
uously.
A considerably reduced operating period after charging indi-
cates that the battery pack is used up and must be replaced.
– To replace the battery pack 18 , loosen nut 19 and remove
the battery pack 18 .
– Mount a new battery pack 18 . Pay attention that the nose of
the battery pack engages in the corresponding recess in the
housing (see illustration on the graphic pages). Firmly tight-
en the battery pack with nut
19 .

Remove the battery pack from the measuring tool when
not using it for longer periods.
When storing for longer pe-
riods, the rechargeable batteries can corrode and self-dis-
charge.
Charge-control Indicator
When the charge-control indicator 6 flashes red for the first
time, the measuring tool can still be operated for approx. 2 h.
When using commercially available batteries/rechargeable bat-
teries, the remaining operating duration may differ.
When the charge-control indicator 6 lights up red continuously,
measurements are no longer possible. The measuring tool
switches off automatically after 1 minute.
Operation
Initial Operation

Protect the measuring tool against moisture and direct
sun light.

Do not subject the measuring tool to extreme tempera-
tures or variations in temperature.
As an example, do not
leave it in vehicles for a long time. In case of large variations
in temperature, allow the measuring tool to adjust to the am-
bient temperature before putting it into operation. In case of
extreme temperatures or variations in temperature, the ac-
curacy of the measuring tool can be impaired.

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 “Accura-
cy Check of the Measuring Tool”, page 32) 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
28 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 sta-
ble in order to avoid operational interruptions due to re-level-
ling.
Switching On and Off
To save energy, only switch the measuring tool on when you are
using it.
– To switch on the measuring tool, press the On/Off button 2 .
This is confirmed by brief flashing of all indicators.
RL25H: Immediately after switching on, the measuring tool
sends out the variable laser beam
14 .
RL25HV: Immediately after switching on, the measuring tool
sends out the variable laser beam
14 and the plumb beam
15 .

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.
