Starting Operation - Bosch LR40G Operating/Safety Instructions Manual

Starting operation

u Protect the laser receiver against mois-
ture and direct sunlight.
u Do not subject the laser receiver to ex-
treme temperatures or variations in tem-
perature. As an example, do not leave it in
vehicles for longer periods. In case of large
variations in temperature, allow the laser
receiver to adjust to the ambient tempera-
ture before putting it into operation. In case
of extreme temperatures or variations in
temperature, the accuracy of the laser re-
ceiver can be impaired.
u Keep the work area free from obstacles
that could reflect or obstruct the laser
beam. For example, cover any reflective or
shiny surfaces. Do not measure through
panes of glass or similar materials. The
measurements may be distorted by a re-
flected or obstructed laser beam.
Setting up the laser receiver (see figure A)
Position the laser receiver so that the laser
beam can reach the reception area (1). Align
it so that the laser beam runs straight through
the reception area (as shown in the figure).
For rotary lasers with multiple operating
modes, select the horizontal or vertical opera-
tion with the highest rotational speed.
Switching On/Off
u A loud audio signal sounds when switch-
ing on the laser receiver. Therefore, keep
the laser receiver away from your ear or
other persons when switching it on. The
loud sound can damage hearing.
To switch on the laser receiver, press the
on/off button (19). All display indicators and
all LEDs light up briefly and an audio signal
sounds.
To switch off the laser receiver, press and
hold the on/off button (19) until all LEDs
briefly light up and the display goes out. With
the exception for the setting of the display
lighting, all settings are saved upon switching
off.
If no button on the laser receiver is pressed
for approx. 10 min and no laser beam reaches
the reception area (1) for 10 min, then the la-
ser receiver will automatically switch itself off
to preserve battery life.
Operation
Connection to the rotary laser
In the default factory setting, the rotary laser
and the supplied laser receiver are already
connected via Bluetooth®. For the existing
connection, the Bluetooth® connection indi-
cator (b) appears in the display of the laser
receiver.
In order to reconnect the laser receiver or
connect an additional laser receiver with the
rotary laser, press and hold the Bluetooth®
button on the rotary laser until the symbol for
establishing a connection to the remote con-
trol/laser receiver appears in the display of
the rotary laser. Then press the X-axis button
(16) and the Y-axis button (15) on the laser
receiver at the same time until P-- appears
in the text display (e). Confirmation as to
whether a connection has successfully been
established will be shown on the display of
the rotary laser.
Confirmation as to whether a connection has
successfully been established will be shown
on the display of the rotary laser. POK will
appear on the text indicator (e) of the laser
receiver.
If the connection between the rotary laser and
the laser receiver cannot be established, PNK
will appear in the text display (e) of the laser
receiver and the error message for a failed
connection will be shown in the display of the
rotary laser. For troubleshooting, consult the
operating instructions for the rotary laser.
Direction indicators
The position of the laser beam in the recep-
tion area (1) is indicated as follows:
– On the display (5) on the front and rear of
the laser receiver by means of the "laser
beam below center line" direction indica-
tor (f), the "laser beam above center line"
direction indicator (j) and the center line
indicator (h)
– Optionally, by means of the red "laser beam
below center line" LED direction indicator
(4), the blue "laser beam above center line"
LED direction indicator (2) and the green
center line LED (3) on the front of the laser
receiver
– By an audio signal (optional).
On the first pass of the laser beam through
the reception area (1) a short audio signal al-
ways sounds and the red "laser beam below
