Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Changing the batteries/rechargeable battery
(see figure A)
To replace the batteries/rechargeable battery, move the
locking mechanism (2) of the battery compartment cover
into position and open the battery compartment
cover (1).
Insert either a charged rechargeable battery (25) or the bat-
tery adapter (23) with fitted batteries into the battery com-
partment until you feel it click into place.
To remove the rechargeable battery (25) or battery ad-
apter (23), press the release button (24) and pull the re-
chargeable battery or battery adapter out of the battery
compartment. Do not use force to do this.
Close the battery compartment cover (1) and move the lock-
ing mechanism (2) into position .

Battery Charge Indicator

The battery charge indicator (d) will indicate the state of
charge of the batteries/rechargeable batteries on the dis-
play:
Indicator Capacity
60 − 100%
30 − 60%
5 − 30%
0 − 5%
If the batteries or rechargeable battery are
empty, a warning message will appear for a
few seconds and the status indicator (12)
will flash red quickly. The measuring tool will
then switch itself off.

Remote control power supply

Using alkali-manganese batteries is recommended to oper-
ate the remote control.
Turn the locking mechanism (38) of the battery compart-
ment cover into position (e.g. using a coin). Open the
battery compartment cover (40) and insert the batteries.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.
Close the battery compartment cover (40) and turn the lock-
ing mechanism (38) of the battery compartment cover into
position .
Remove the batteries from the remote control when
u
not using it for longer periods. The batteries can cor-
rode and self-discharge during prolonged storage in the
remote control.
Note: The Bluetooth® function remains active as long as bat-
teries are fitted in the remote control. The batteries can be

removed in order to prevent energy consumption by this
function.

Operation

Protect the measuring tool and remote control against
u
moisture and direct sunlight.
Do not expose the measuring tool or remote control to
u
any extreme temperatures or variations in temperat-
ure. 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 remote control to adjust
to the ambient temperature before putting them into op-
eration. Before continuing work with the measuring tool,
always perform an accuracy check (see "Accuracy Check
of the Measuring Tool", page 44).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
Avoid substantial knocks to the measuring tool and
u
avoid dropping it. Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page 44).

Starting Operation of the remote control

The remote control will only work if it is fitted with batteries
that are sufficiently charged.
After pressing a button on the remote control, the signal
transmission indicator (33) will light up, indicating that a sig-
nal has been sent out.
The indicators on the remote control only light up if a setting
has been adjusted via the remote control.
It is not possible to switch the measuring tool on/off with the
remote control.

Starting Operation of the rotary laser

Setting up the measuring tool

Horizontal position
Vertical position
Position the measuring tool on a stable surface in the hori-
zontal or vertical position, mount it on the tripod (44) or on
the wall mount (45) with the alignment unit.
Due to its high levelling accuracy, the measuring tool is very
sensitive to knocks and vibrations and changes in position.
