Assembly
Inserting/Replacing the Battery
Use only alkali-manganese or rechargeable batteries.
Fewer measurements are possible when using 1.2 V rechargeable batter-
ies as compared with 1.5 V batteries.
To open the battery lid
15
, press the latch of the battery lid
14
in the direc-
tion of the arrow and remove the battery lid. Insert the supplied batteries.
When inserting, pay attention to the correct polarity according to the rep-
resentation on the inside of the battery compartment.
When the
battery symbol appears in the display for the first time, then
at least 100 measurements are still possible. The batteries must be
replaced when the battery symbol flashes; taking measurements is no
longer possible.
Always replace all batteries at the same time. Only use batteries from one
brand and with the identical capacity.
f
Remove the batteries from the measuring tool when not using
it for extended periods.
When storing for extended periods, the bat-
teries can corrode and discharge themselves.
Operation
Initial Operation
f
Protect the measuring tool against moisture and direct sun
irradiation.
f
Do not expose the measuring tool to extreme temperatures or
variations in temperature.
Switching On and Off
To
switch on
the measuring tool, either press the On/Off button
12
or the
measuring button
8
. When switching on the measuring tool, the laser beam
is not switched on yet.
To
switch off
the measuring tool, press the On/Off button
12
.
To save the batteries, the measuring tool switches off automatically after
approx. 5 minutes when no measurement is carried out.
When a measured value has been stored, it is retained in automatic switch-
off mode. When switching on the measuring tool again,
“M”
is indicated in
the display.
Measuring Procedure
The measuring tool offers a variety of different measuring functions that can
be selected by pushing the corresponding function button (see “Measuring
Functions”). After switching on, the measuring tool is in the “length meas-
urement function”.
Upon selection of the measuring function, all further steps are carried out
by pushing the measuring button
8
.
All measuring values are determined from the rear edge of the measuring
tool (
e
symbol in display). Therefore, position the rear edge of the measur-
ing tool against the desired measuring line (e.g. a wall) for all measure-
ments.
