CHAPTER
1
Safety Recommendations
The Trimble GX™ 3D scanners version comply with the performance
requirements of US FDA 21 CFR §1040.10 as a Class 2 laser product, and
are therefore labeled as follows in accordance with the requirements of this
standard.
The Trimble GX™ 3D scanners version also comply with the performance
requirements of IEC 60825-1 as a Class 3R laser product and are therefore
labeled as follows in accordance with the requirements of this standard.
Introduction - 1
Warning: Direct intra-beam viewing is potentially hazardous.
Caution: Under normal operating conditions, the laser beam represents a
minimal hazard to the eye. The presence of a laser safety officer is not
required. Eye-protection is not required. Do not look directly into the beam.
Do not look into the beam with an optical instrument (e.g. binoculars). Failure
to comply with this warning may lead to prolonged exposure of the retina to
the beam and therefore injury.
Warning: Do not attempt to use the instrument for applications other than
those for which it is intended.
Caution: Please ensure that you are aware of any national laws and
regulations applicable in the country of operation, concerning laser safety
precautions and any other occupational safety and health issues that may be
encountered. All national laws and regulations take precedent over foreign or
international standards.
Trimble GX™ 3D Scanner User Guide - 3
1 - Introduction
Caution: The covers and other housing materials of this instrument are
designed and built to provide worker protection from laser radiation hazards.
However, misuse of the instrument or unauthorized access into the
instrument may result in worker exposure to such hazards. Please read and
ensure that you understand all of the warnings and precautions in this User
Manual before operating the instrument. Failure to do so may result in
personal injury and/o damage to the instrument and ancillary items.
Caution: Do not remove covers, panels or any other parts of the instrument
housing. Only approved Trimble Service Centers are authorized to carry out
such operations. Failure to comply with this precaution may lead to exposure
to potentially hazardous conditions, and may imply a requirement to
recalibrate the instrument.
Caution: Unauthorized removal of covers, panels or any constituent part of
the instrument housing will void all warranties.
Caution: Do not tamper with nor open the laser diode housing or any other
constituent part of the instrument. Do not operate the instrument when
covers, panels or any other part of the instrument housing are removed. Only
trained, authorized and suitably protected personnel at Trimble Service
centres may carry out operations in these conditions. Failure to comply with
this precaution may lead to exposure to potentially hazardous conditions, and
implies a requirement to recalibrate the instrument.
Caution: Unauthorized operations on, or removal/replacement of constituent
parts of the instrument will void all warranties.

Use Recommendations
Read this manual thoroughly. Do not attempt to use the instrument for
applications other that those for which it is intended. If, to the best of your
knowledge, there are no national laws, regulations or guidelines concerning
laser safety, you may consider implementing any of the following:
Ensure that persons do not look directly into the beam.
Do not look into the beam with an optical instrument.
Keep out of the scanning zone (remain behind the 3D scanner).
Keep other people present behind the 3D scanner and away from
the scanning zone.
Do not look at the 3D scanner window during scanning.
Work preferably under normal lightning so that the eye pupil is kept
small (2 mm typically), thereby minimizing the laser power that can
reach the retina.
The laser beam should be terminated at the end of its useful beam
path. Scanner pilot software may include settings to limit beam
distance.
The laser beam should be located well above or below the eye
wherever practicable.
Precautions should be taken to ensure that the laser beam is not
aimed unintentionally at mirror like surfaces.
When not in use the laser instrument should be stored in a location
where unauthorized personnel can not gain access.
These recommendations do not replace those safety precautions which may
be the subject of national laws and/or regulations in the country of operation.
Prohibited uses include, but are not limited to:
Use of this instrument without proper training by the manufacturer or
its representatives.
Use of this instrument outside the range conditions specified inside
this user manual.
Unauthorized modification of the instrument and/or its components.

Inspection, Care and Maintenance - 2
Inspecting the Instrument Case
First, open the shipping box and then remove the four top foam paddings and
the instrument case from it. Do not throw the shipping box with the foam
paddings (eight at all); you may need it later for transporting the Trimble GX™
3D scanner inside its case.
Inspect the instrument case. If the instrument case arrives in poor condition,
examine the items inside for visible damage. If damage is found, immediately
notify the carrier and your Trimble sales representative. Keep the shipping
box and the instrument case as well as the packing material for the carrier to
inspect.
Caution: Never attempt to lift the instrument case full of items without using
appropriate means. Do not use human effort to perform this operation. Back
injuries can be caused if the following recommendations are not respected.
Unpacking the Instrument Case
When unpacking the instrument case, check that the items listed below are
inside. If you notice that anything is missing or damaged, please contact the
manufacturer or your retailer immediately. Below is an example of where all
items can be placed in the instrument case.

Operating Instructions
The Trimble GX™ 3D scanner, classified IP53 according to international
standard IEC 60529, is a night and day scanner being able to scan in:
Wet or dry weather (humidity range from 0 to 80%),
Hot or cold conditions (temperature range from 0 to +40° Celsius).
Transportation Instructions
The Trimble GX™ 3D scanner has been tested for resistance to shock and
vibration according to the international standard IEC 60721 and is classified
2M2 (instrument alone) and 2M3 (instrument in its case).
Trimble GX™ 3D Scanner User Guide - 11
2 - Inspection, Care and Maintenance
Recommendations:
Use the instrument case to carry your Trimble GX™ 3D scanner. It is
designed to protect it against shock and vibration.
Fix the following warning label to your instrument (or shipping) case:
HANDLE WITH CARE.
Ensure that no custom documents and issues are missing to avoid
having delivery problems.
Always transport the Trimble GX™ 3D scanner inside the instrument
case inside the original shipping box (including all original foam
paddings).
Caution: Insure your Trimble GX™ 3D scanner against unforeseen damage
if you decide to use a carrier's services.
Cautions:
Ensure that the instrument case is completely closed before moving or
carrying it.
In the event of using the Trimble backpack as a luggage, take care not to
bang your Trimble GX™ 3D scanner against any heavy objects.
Storage Instructions
The Trimble GX™ 3D scanner can be stored inside its box at temperatures
ranging from -20 to +50°C.
Servicing Instructions
Never spill liquid of any kind on the Trimble GX™ 3D scanner.
Unplug the instrument from the power supply unit and from the notebook PC
(or from the Trimble Recon™ controller) before cleaning or polishing it. Do
not use liquid cleaners or aerosol cleaners. Use a cloth lightly dampened with
water for cleaning the exterior of the instrument.
The air outlets at the right and left sides of the instrument are provided for
necessary ventilation. To ensure reliable operation of the instrument, and to
protect it from overheating, these air outlets must ever be blocked or covered,
except in very cold conditions

Instrument Principle
The Trimble GX™ 3D scanner is composed of a time-of-flight range finder
and optical encoders as measurement instruments. A time-of-flight range
finder has a laser that emits a pulsed beam (or a wave) towards an object.
The pulse is reflected by the scanned object's surface and part of the light
returns to the receiver. The pulse level is compared to a threshold. When it
reaches the threshold, a logical start or stop signal is generated. The time
needed for the laser pulse to travel from the 3D scanner to the scanned
object and back again is measured. The distance of the object from the 3D
scanner can then be calculated using the known speed of light.
Figure 9 - Instrument principle 1
The Trimble GX™ 3D scanner calculates 3D coordinates of a scanned point
by measuring (as shown in the illustration below):
The distance r, which is calculated by the time-of-flight range finder,
The elevation Θ and azimuth Φ, which are measured by optical
encoders.
