Operation
Initial Operation
Protect the measuring tool against direct sunlight.
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do not
leave it in vehicles for long time. In case of large variations in
temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. In case of
extreme temperatures or variations in temperature, the
accuracy of the measuring tool can be impaired.
Position the laser receiver in such a manner that the laser beam
can reach the reception area 35. If the rotational laser has sev-
eral rotational speeds, set the speed to 600 min
Switching On and Off
A loud audio signal sounds when switching on the meas-
uring tool. "At a distance of 0.2 m, the A-weighted sound
pressure level of the audio signal can be up to 99 dB(A)."
Do not hold the measuring tool close to your ear! The loud
audio signal can cause hearing defects.
To switch on the measuring tool, press the On/Off button 42.
An audio signal sounds and all display indicators light up briefly.
To switch off the measuring tool, press the On/Off button 42
again. This is confirmed by a double beep.
When no pushbutton on the measuring tool is pressed for ap-
prox. 7 minutes and when no laser beam is impinged upon the
reception area 35 for 7 minutes, the measuring tool switches
off automatically to save the batteries.
Selecting the Setting of the Centre Indicator
With button 33, you can specify the accuracy with which the
position of the laser beam is indicated as centred on the recep-
tion area:
– "Fine" adjustment, (indication a on the display),
– "Medium" adjustment, (indication b on the display),
– "Coarse" adjustment, (indication c on the display).
When changing the accuracy setting, a single, two or three
beeps sound, depending on the selected setting.
The accuracy setting is stored when switching off the measuring
tool.
Direction Indicators
The position of the laser beam on the reception area 35 is indi-
cated:
– via the direction indicators "move downward" d, "move up-
ward" f or the centre indicator e on the display 36 on the
front and back side of the measuring tool,
– via the LEDs "move downward" 38, "move upward" 41 or the
centre-indication LED 39 on the front side of the measuring
tool,
– optionally via the audio signal (see "Audio Signal for Indica-
tion of the Laser Beam", page 36).
Measuring tool too low: When the laser beam runs through the
top half of the reception area 35, direction indicator f on the
display and the corresponding red LED 41 light up.
When the audio signal is switched on, a slow-beat signal sounds.
Move the measuring tool upward in the direction of the arrow.
When approaching the centre mark, two or three bars are indi-
cated in direction indicator f.
36 | English
Measuring tool too high: When the laser beam runs through
the bottom half of the reception area 35, direction indicator d
on the display and the corresponding red LED 38 light up.
When the audio signal is switched on, a fast-beat signal sounds.
Move the measuring tool downward in the direction of the ar-
row. When approaching the centre mark, two or three bars are
indicated in direction indicator d.
Measuring tool in the centre position: When the laser beam
runs through the reception area 35 at the centre mark 40, the
centre indicator e on the display and the corresponding blue
LED 39 light up. When the audio signal is switched on, a contin-
uous signal sounds.
When the measuring tool is moved such that the laser beam
leaves the reception area 35 again, then the last displayed di-

.
rection indicator f or d on the display as well as the correspond-
ing LED 41 or 38 flash for approx. 5 seconds.
The direction indicator LEDs can be switched off to save the
batteries. To switch the LEDs on or off, press and hold the but-
ton for adjustment of the measuring accuracy 33 and briefly
press the On/Off button 42. This is confirmed by brief flashing
of all LEDs. When the LEDs were switched on, they additionally
light up for 1 s.
Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 35 can be
indicated via an audio signal.
The following audio signal settings are possible:
– An audio signal with high frequency and two available
volume levels,
– Audio signals in three lower frequencies and one available
volume level each,
– An audio signal for indication of the laser beam being
switched off.
To change the volume level or switch off the audio signal, push
the acoustic signal button 34 until the requested volume level is
indicated on the display. At low volume level, the audio signal in-
dicator h appears on the display with one bar; at high volume
level, the indicator appears with three bars (only available for
the highest frequency). When the audio signal is set to off, the
indicator goes out. When pressing the audio signal button, a
short audio signal sounds first for confirmation, then a second
short audio signal sounds in the selected volume level.
Independent of the selected audio signal setting, a short beep
for confirmation sounds at low volume level and the set frequen-
cy each time a button is pressed on the measuring tool.
To change the frequency, press and hold the audio signal button
34 and briefly press the On/Off button 42. A brief audio signal in
the selected frequency sounds each time for confirmation.
The signal tone setting is maintained after switching the meas-
uring tool off and on again.
Working Advice
Strobe shield
The measuring tool is equipped with an electronic filter for
bright sunlight. The filter prevents, e.g., interference from the
warning lights of construction machines. Effective operation of
the filter is possible only when sensor 37 is not obstructed and
clean.
