Audio Signal for Indication
of the Laser Beam
The position of the laser beam on the recep-
tion area 5b can be indicated via an audio
signal.
The volume level can be increased or
switched off.
To change the volume level or switch the au-
dio signal off, push the acoustic signal but-
ton 4b until the desired volume level is in-
dicated on the display. At low volume level,
the audio signal indicator 28b appears on the
display with one bar; at high volume level,
the indicator appears with three bars. When
the audio signal is set to off, the indicator
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.
Every time when the laser receiver is
switched on, the volume setting is stored
from before the receiver was switched off.
Backlight
The back light of the display is switched on
at full strength when the laser receiver is
switched on. If no laser beam is detected and
no buttons are pressed for 1 minute, the back
light switches off automatically.
The backlight 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 accuracy setting button 2b and the audio
signal button 4b simultaneously
Working Advice
Marking
When the laser beam runs through the cen-
ter of the reception area 5b, its height can be
marked at the center mark 11b 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 J)
When a positive-lock attachment is not abso-
lutely required, the magnets 7b on top of the
laser receiver can be used to attach the re-
ceiver to steel parts.
Keep the laser receiver clean at all times.
Do not immerse the laser receiver into
water or other fluids.
Wipe off debris using a moist and soft
cloth. Do not use any cleaning agents or
solvents.
If the laser receiver should fail despite the
care taken in manufacturing and testing
procedures, repair should be carried out by
an authorized after-sales service center for
Bosch power tools.
In all correspondence and spare parts
orders, please always include the 10-digit
article number given on the type plate of
the tool.
ENVIRONMENT PROTECTION
Recycle raw materials & batteries
instead of disposing of waste.
The unit, accessories, packag-
ing & used batteries should
be sorted for environmentally
friendly recycling in accordance with the lat-
est regulations.
