Assembly
Inserting/Replacing the Batteries
Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
Less measurements are possible when using 1.2 V recharge-
able batteries than with 1.5 V batteries.
To open the battery compartment 22, turn the locking knob
23 to position and pull out the battery compartment.
When inserting the batteries/rechargeable batteries, pay at-
tention to the correct polarity according to the representation
on the inside of the battery compartment.
1 609 92A 1YW | (8.7.16)
When the battery symbol appears for the first time on the
display, at least 100 individual measurements are still possi-
ble. The continuous measurement mode is deactivated.
When the battery symbol flashes, the batteries/recharge-
able batteries must be replaced. Measurements are no longer
possible.
Always replace all batteries/rechargeable batteries at the
same time. Do not use different brands or types of batter-
ies/rechargeable batteries together.
 Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargea-
ble batteries can corrode and self-discharge.
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 longer periods. In case of large
variations in temperature, allow the measuring tool to ad-
just to the ambient temperature before putting it into oper-
ation.
 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", page 24) each time
before continuing to work.
Switching On and Off
 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.
For switching on the measuring tool, the following possibili-
ties are given:
– Pressing the On/Off button 16: The measuring tool is
switched on and is in length measurement mode. The laser
is not activated.
– Briefly pressing the measuring button 7: Measuring tool
and laser are switched on. The measuring tool is in length
measurement mode.
– Pressing the measuring button 7 for several seconds:
Measuring tool and laser are switched on. The measuring
tool is in continuous measurement mode.
 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.
To switch off the measuring tool, press the On/Off button 16
for a few seconds.
When no button on the measuring tool is pressed for approx.
5 minutes, the measuring tool automatically switches off to
save the batteries.
When switching off automatically, all stored values are re-
tained.
