Initial Operation
• Protect the laser receiver against moisture
and direct sunlight.
• Do not subject the laser receiver to extreme
temperatures or variations in temperature.
As an example do not leave it in vehicles for
a long time. In case of large variations in tem-
perature, allow the laser receiver to adjust to
the ambient temperature before putting it into
operation. In case of extreme temperatures or
variations in temperature, the accuracy of the
laser receiver can be impaired.
Setting up the Laser receiver
(see figure I)
Position the laser receiver at least 20 inches
away from the rotational laser.
Position the laser receiver in such a manner
that the laser beam can reach the reception
area 5b. Align the laser receiver in such a man-
ner that the laser beam runs laterally through
the reception area (as shown on the figure).
Switching On and Off
• A loud audio signal sounds when switching
on the tool. Therefore, keep the tool away
from your ear or other people when switch-
ing on. The loud audio signal can cause hear-
ing defects.
To switch the laser receiver On, press the On/
Off button 3b. All display indicators as well as
all LEDs light up briefly and an audio signal
sounds.
Every time when the laser receiver is switched
on, both volume and accuracy settings are
stored from the last setting before the receiv-
er was switched off.
To switch the laser receiver Off, press the On/
Off button 3b again. All LEDs and all display
indicators light up briefly before the receiver
switches off, and an audio signal sounds.
If no buttons on the laser receiver are pressed
and no laser beam reaches the reception area
5b, for approx. 10 mins, the laser receiver
switches off automatically to save energy. The
switching off is indicated by all LEDs and all
display indicators lighting up briefly, and an
audio signal sounding.

LR10 Operation
Selecting the Accuracy setting
With button 2b, you can specify with which
accuracy the position of the laser beam is in-
dicated on the reception area:
– "Fine" adjustment (indication 27b on the
display),
– "Coarse" adjustment (indication 26b on
the display).
Every time when the laser receiver is
switched on, the accuracy setting is stored
from before the receiver was switched off.
The position of the laser beam on the recep-
tion area 5b is indicated:
– by the direction indicators "move down-
ward" 23b, "move upward" 25b or center
24b on the display 6b on the front of the
laser receiver,
– by the LEDs "move downward" 10b, "move
upward" 12b or center 9b on the back of
the laser receiver,
– optionally by the audio signal (see "Audio
Signal for Indication of the Laser Beam")
Laser receiver too low: If the laser beam runs
through the upper half of the reception area
5b, the direction indicator 25b on the display
and the corresponding LED 12b light up. If the
audio signal is switched on, a signal sounds
at high frequency. Move the laser receiver up-
ward in the arrow direction.
Laser receiver too high: If the laser beam
runs through the lower half of the reception
area 5b, the direction indicator 23b on the
display and the corresponding LED 10b light
up. If the audio signal is switched on, a signal
sounds at low frequency. Move the laser re-
ceiver downward in the arrow direction.
Laser receiver in center position: When the
laser beam runs through the reception area
5b at the center mark 11b, the center indica-
tor 24b on the display and the corresponding
center-indicator LED 9b light up. When the au-
dio signal is switched on, a continuous signal
sounds.
