Protection rating
A) Depends on the rotary laser
B) The working range may be reduced by unfavourable environ-
mental conditions (e.g. direct sunlight).
C) Dependent on the distance between the laser receiver and the
rotary laser and on the laser class and laser type of the rotary
laser
D) The reception accuracy may be reduced by unfavourable envir-
onmental conditions (e.g. direct sunlight).
E) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
F) When the audio signal and display illumination are switched off
For clear identification of your laser receiver, see the serial number
(12) on the type plate.
Assembly
Inserting/Changing the Batteries
Alkali-manganese batteries are recommended for the laser
receiver.
Bosch Power Tools
Pull the locking mechanism (14) of the battery compartment
cover outwards and lift up the battery compartment cover
(13). Insert the batteries.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.

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

are not using it for a prolonged period of time. The bat-

Do not subject the laser receiver to extreme temperat-
u
ures or variations in temperature. As an example, do
0.35 kg
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the laser receiver to ad-
158 × 80 × 34 mm
just to the ambient temperature before putting it into op-
eration. In case of extreme temperatures or variations in
IP 66
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)
Place the laser receiver at least 0.5 m away from the rotary
laser. For rotary lasers with multiple operating modes, select
the horizontal or vertical operation with the highest rota-
tional speed.
Position the laser receiver so that the laser beam can reach
the reception area (11). Align it so that the laser beam runs
straight through the reception area (as shown in the figure).
Switching On/Off
A loud audio signal sounds when switching on the
u
laser receiver. Therefore, keep the laser receiver
