Indicator Capacity
0 − 2%
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Take the batteries out of the laser receiver when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the laser receiver.
Rotary Laser Battery Charge Indicator
The battery charge indicator (a) shows the state of charge of
the battery pack/batteries of the rotary laser, provided that
the rotary laser is switched on and a Bluetooth® connection
has been established between the laser receiver and the
rotary laser.

Operation
Starting operation
Protect the laser receiver against moisture and direct
u
sunlight.
Do not subject the laser receiver to extreme temperat-
u
ures or variations in temperature. As an example, do
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the laser receiver to ad-
just to the ambient temperature before putting it into op-
eration. In case of extreme temperatures or variations in
temperature, the accuracy of the laser receiver can be im-
paired.
Keep the work area free from obstacles that could re-
u
flect or obstruct the laser beam. For example, cover
any reflective or shiny surfaces. Do not measure
through panes of glass or similar materials. The meas-
urements may be distorted by a reflected 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 operation with the highest rotational
speed.
Bosch Power Tools
Switching On/Off
A loud audio signal sounds when switching on the
u
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 of the setting for the display
lighting, all settings are saved when the laser receiver is
switched 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 laser receiver will automatically switch it-
self off to preserve battery life.
Connection to the Rotary Laser
In the default factory setting, the rotary laser and the sup-
plied laser receiver are already connected via Bluetooth®.
For the existing connection, the Bluetooth® connection
indicator (b) appears in the display of the laser receiver.
To reconnect the laser receiver or to connect an additional
laser receiver with the rotary laser, press and hold the
Bluetooth® button on the rotary laser until the symbol for es-
tablishing a connection to the remote control/laser receiver
appears in the display of the rotary laser. Then press and
hold the X‑axis button (16) and Y‑axis button (15) on the
laser receiver 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. POK will appear on the text indicator (e) of the laser
receiver.
If the connection between the rotary laser and the laser re-
ceiver 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 instruc-
tions for the rotary laser.
Direction indicators
The position of the laser beam in the reception area (1) is in-
dicated as follows:
– On the display (5) on the front and rear of the laser re-
ceiver by means of the "laser beam below centre line" dir-
ection indicator (f), the "laser beam above centre line"
direction indicator (j) and the centre line indicator (h)
– Optionally, by means of the red "laser beam below centre
line" LED direction indicator (4), the blue "laser beam
above centre line" LED direction indicator (2) and the
green centre 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 always sounds and the red
"laser beam below centre line" LED direction indicator (4)
and the blue "laser beam above centre line" LED direction
