User's Manual

1. Push the battery into the tool.
2. Turn the catch in a clockwise direction to the
second detent (the “locked” symbol is displayed).
6.5 Removing the battery 9
1. Turn the catch in a counterclockwise direction
from the second detent back to the “open” posi-
tion (the “unlocked” symbol is displayed).
2. Pull the battery out of the tool.
6.6 Switching the tool on
Press the “On / off” button.
NOTE
After switching on, the tool begins the automatic lev-
eling process (takes max. 40 seconds). After comple-
tion of the leveling process, the laser beam switches
on and begins to rotate in the normal direction. When
leveling in the horizontal plane the laser head rotates
automatically at medium speed and, when working
in the vertical plane, a reference point is projected
downwards.
6.7 LED indicators
Please refer to section 2 “Description”.
6.8 Inserting batteries in the PRA 35 
CAUTION
Do not use damaged batteries.
DANGER
Do not mix old and new batteries. Do not mix batteries
of different makes or types.
NOTE
The PRA 35 may be powered only by batteries man-
ufactured in accordance with the applicable interna-
tional standards.
6.9 Pairing
NOTE
In the state supplied, the PR 35 rotating laser and the
PRA 35 remote control / laser receiver have not been
paired. They cannot operate together until they have
been paired.
The PR 35 rotating laser and the PRA 35 must be set
to operate as a pair before they can be used together.
Pairing the tools means that they are configured to
communicate with each other. The PR 35 rotating
laser then receives signals only from the PRA 35 with
which it has been paired. Pairing makes it possible to
work alongside other rotating lasers without risk of
settings being altered inadvertently by these tools.
1. Press the “On / off” buttons on the PR 35 rotating
laser and on the PRA 35 simultaneously (or on
the PRA 90 if this tool is being used) and keep
the buttons pressed for at least 3 seconds.
When pairing has been carried out successfully, a
signal tone is emitted by the PRA 35 and all LEDs
on the PR 35 rotating laser blink.
2. Switch off the tools that have been paired and
then switch them on again.
The “Paired” symbol appears in the display (see
“Troubleshooting” section).
7. Operation
7.1 Switching the tool on
Press the “On / off” button.
NOTE
After switching on, the tool begins to level itself
automatically.
7.2 Working with the PRA 35
The PRA 35 is a laser receiver (front) and, at the
same time, a remote control unit (rear). The remote
control makes working with the rotating laser more
convenient and is required in order to make use of
certain functions.
