First use
Remove any protective films where applied. Open the battery compartment and ins-
ert batteries, please taking care to observe the indicated polarity.
Turn the transportation lock (3) to the “ON” position. The pendulum levelling mecha-
nism is released, and the instrument is able to align itself on its own. Make sure that
the instrument is not on too much of a slope (within 3°). If the slope of the instrument
should exceed 3°, the lasers will flash or will go out automatically. Use the adjustable
feet
(9)
or locate the tripod so that the air-bubble is within the instrument’s levelling
range.
Important
For the Dotted Lines versions, use the projected dots only as a reference to find the
laser line. Only the projected laser line may be used to obtain a correct measurement
result.
Horizontal alignment
After disengagement of the pendulum locking system, and provided the instrument
is within its levelling range, the horizontal line is levelled. You can activate or deactiva-
te the horizontal lines using the “H”-button (10). Press the number of times this button
to get the desired number of laser lines.

It is advisable to place the horizontal line on your working height.
Attention:
∙ Cross line lasers can only be used on tripods which are adjustable in height, such as
cranked or telescopic tripods.
∙ If the workplace is very brightly lit, e.g. out of doors, it may be necessary to use the
laser receiver.
