Laser receiver too high: If the laser beam
r
uns through the lower half of the reception
area 6, the direction indicator 22 on the dis-
play will light up and offset display segments
20/21 will also light up depending on the se-
lected unit of measurement. If the audio sig-
nal is switched on, laser receiver shows fast
beeping sound. Move the laser receiver down-
wards in the arrow direction.
If the laser beam is more than 30mm (1.18
inches) below the center mark of the receiver,
only the direction indicator 22 on the display
will light up. If the audio signal is switched
on, laser receiver shows fast beeping sound.
Move the laser receiver downwards in the ar-
row direction. If the laser reception is inter-
rupted due to a physical obstruction, the di-
rection indicator 22 will flash for 3 seconds
to indicate the last position of the laser beam.
Laser receiver in center position: When the
laser beam runs through the reception area 6
at the center mark 13, the center indicator 23
on the display will light up and offset display
segments 20/21 will also light up depending
on the selected unit of measurement. If the
audio signal is switched on, laser receiver
shows continuous sound. If the laser recep-
tion is interrupted due to a physical obstruc-
tion, the center indicator 23 will flash for 3
seconds to indicate the last position of the
laser beam.
Strobe Detection
If strobe light (e.g. LED lights) is present,
avoid the strobe light from reaching the laser
receiver.
In case of strobe light disturbance an error
will be indicated by:
-flashing of the selected measurement unit
-No offset value will be displayed on the front
7 and rear display 12.
Audio Signal for Indication
of the Laser Beam
The position of the laser beam on the recep-
tion area 6 can be indicated via an audio sig-
nal.
The volume level can be adjusted or switched
off.
To change the volume level or switch the
audio signal off, push the acoustic signal
button 4 until the desired volume level is in-
dicated on the display. At low volume level,
the audio signal indicator 18 appears on the
display with no bar ; at high volume level,
the indicator appears with one curve bar .
When the audio signal is set to off, the indica-
tor goes out. Independent of the audio signal
setting, a short beep sounds at low volume
level each time a button is pressed on the
laser receiver.
Display Back-light
The back-light of the display is switched on
when the laser receiver is switched on. If no
laser beam is detected and no buttons are
pressed for 2 minutes, the back-light switches
off automatically.
The back-light also switches off automatically
if there is continuous laser detection and no
buttons are pressed for 2 minutes. The back-
light can be switched off manually by pressing
the display back-light button 5.
Working Advice
Marking
When the laser beam runs through the cen-
ter of the reception area 6, its height can be
marked at the center mark 13 right and left of
the laser receiver.
When marking, make sure to align the laser
receiver both vertically and horizontally. If this
is not done the laser marks will be offset from
the laser beam.
Attaching with the Magnet
(see figure B)
When a mounting bracket is not absolutely
required, the magnets 8 on top of the laser
receiver can be used to attach the receiver to
steel parts.
