between the models they are clearly described.
The appearance of the products is subject to change without
notice. The appearance of the actual product may vary slightly
from the product shown in the illustrations.
Telescope •Measuring with P modes: When measuring distances to a reflector
with Electronic Distance Measurement (EDM) mode “P”, the telescope
uses a wide visible red laser beam, which emerges coaxially from the
objective of telescope.
•Measuring with NP modes: Instruments that are equipped with a
reflectorless EDM additionally offer the EDM mode “NP”. When meas-
uring distances with this EDM mode, the telescope uses a narrow
visible red laser beam, which emerges coaxially from the objective of
telescope.
Do NOT remove the battery during operation of the instrument, or during the shutdown procedure.
This can result in a file system error and data loss!
Always switch off the instrument by pressing the On/Off key, and wait until the instrument has shutdown
completely before removing the battery.

1.6.3 Distancer, Measurements without Reflectors (NP mode)
General The EDM module built into the product produces a visible laser beam which emerges from the telescope
objective.
The laser product described in this section is classified as laser class 3R in accordance with:
• IEC 60825-1 (2007-03): "Safety of laser products"
• EN 60825-1 (2007-10): "Safety of laser products"
Direct intrabeam viewing may be hazardous (low eye hazard level), in particular for deliberate ocular expo-
sure. The beam may cause dazzle, flash-blindness and after-images, particularly under low ambient light
conditions. The risk of injury for laser class 3R products is limited because of:
a) unintentional exposure would rarely reflect worst case conditions of (e.g.) beam alignment with
the pupil, worst case accommodation,
b) inherent safety margin in the maximum permissible exposure to laser radiation (MPE)
c) natural aversion behaviour for exposure to bright light for the case of visible radiation.
CAUTION From a safety perspective, class 3R laser products should be treated as potentially hazardous.
Precautions:
1) Prevent direct eye exposure to the beam.
2) Do not direct the beam at other people.
CAUTION Potential hazards are not only related to direct beams but also to reflected beams aimed at reflecting
surfaces such as prisms, windows, mirrors, metallic surfaces, etc.
Precautions:
1) Do not aim at areas that are essentially reflective, such as a mirror, or which could emit unwanted
reflections.
2) Do not look through or beside the optical sight at prisms or reflecting objects when the laser is switched
on, in laser pointer or distance measurement mode. Aiming at prisms is only permitted when looking
through the telescope.

1 Extend the tripod legs to allow for a comfortable working posture. Position the tripod over the marked
ground point, centring it as best as possible.
2 Fasten the tribrach and instrument onto the tripod.
3 Turn on the instrument, and, if tilt correction is set on, the laser plummet activates automatically, and
the Level up screen appears. Otherwise, tap on Level/Face icon in status bar.
4 Move the tripod legs (1) and use the tribrach footscrews (6) to center the plummet (4) over the ground
point.
5 Adjust the tripod legs (5) to level the tubular level (7).
6 Use the electronic level and turn the tribrach footscrews (6) to level the instrument precisely.
7 Center the instrument precisely over the ground point by shifting the tribrach on the tripod plate (2).
8 Repeat steps 6 and 7 until the required accuracy is achieved.
When setting up the tripod pay attention to ensuring
a horizontal position of the tripod plate. Slight correc-
tions of inclination can be made with the foot screws
of the tribrach. Larger corrections must be done with
the tripod legs.
Loosen the clamping screws on the tripod legs, pull out
to the required length and tighten the clamps.
a) In order to guarantee a firm foothold sufficiently
press the tripod legs into the ground.
b) When pressing the legs into the ground note that
the force must be applied along the legs.
Careful handling of tripod.
• Check all screws and bolts for correct fit.
• During transport always use the cover supplied.
• Use the tripod only for surveying tasks.
