Although the product meets the strict regulations and standards which are in
force in this respect, Leica Geosystems cannot completely exclude the possi-
bility that other equipment may be disturbed.
▶The product is a Class A product. In a domestic environment this prod-
uct may cause radio interference in which case the user may be
required to take adequate measures.
CAUTION
Disturbances in other equipment
There is a risk that disturbances may be caused in other equipment if the
product is used with accessories from other manufacturers, for example field
computers, personal computers or other electronic equipment, non-standard
cables or external batteries.
Precautions:
▶Use only the equipment and accessories recommended by Leica Geo-
systems.
When combined with the product, they meet the strict requirements
stipulated by the guidelines and standards.
▶When using computers, two-way radios or other electronic equipment,
pay attention to the information about electromagnetic compatibility
provided by the manufacturer.
CAUTION
Disturbances caused by electromagnetic radiation can result in erro-
neous measurements.
Although the product meets the strict regulations and standards which are in
force in this respect, Leica Geosystems cannot completely exclude the possi-
bility that function of the product may be disturbed by intense electromag-
netic radiation, for example, near radio transmitters, two-way radios or diesel
generators.
Precautions:
▶Check the plausibility of results obtained under these conditions.
Safety Directions 13

CAUTION
Operating the product with connecting cables attached at only one of
their two ends
If the product is operated with connecting cables attached at only one of
their two ends, for example external supply cables, interface cables, the per-
mitted level of electromagnetic radiation may be exceeded and the correct
functioning of other products may be impaired.
Precautions:
▶While the product is in use, connecting cables, for example product to
external battery, product to computer, must be connected at both ends.
1.8 FCC Statement, Applicable in U.S.
WARNING
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environ-
ment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his
own expense.
WARNING
Changes or modifications not expressly approved by Leica Geosystems for
compliance could void the user's authority to operate the equipment.

can give an acoustical status information. For example, the following status
information is indicated by different acoustic signals:
•Laser Tracker beam locked on and ready to measure
•Measurement completed
•6DOF not available
•Laser beam broken

2.5 General Operating Principle
The T‑Scan sensor is a triangulation scanner using an optically amplified laser
line observed by a 2D imaging sensor.
The T‑Scan sensor has a working range (measurement depth) of approxi-
mately ±50 mm. The mid working distance is the distance from the housing
to the centre of the working range. This distance is also called Stand-off and
amounts approximately 150 mm. The usable scan width at stand-off is
approximately 100 mm.

a Minimum working distance
b Mid working distance

e Working range
In order to facilitate the positioning of the T‑Scan sensor, the sensor emits a
pilot beam. The pilot beam intersects the laser beam at the centre of the
working range. If the pilot beam is underneath the scan line, the distance
between sensor and measuring object is too small. If the pilot beam is above
the scan line, the distance is too large.
