2 Safety Summary
Introduction
This chapter lists and describes the safety issues applicable to the
standard configurations of the RTR-4. The summaries listed here
apply at all times and shall be strictly followed by all operators,
technicians, and observers.
Follow all warnings and instructions
The equipment and the procedures in this manual have warning
and caution labels and their relevant hazard type symbols.
Observe all warnings, cautions, and instructions marked on the
equipment and included in this manual and in all supporting
manufacturer documentation at all times.
Qualified and Trained personnel only
The RTR-4 should only be operated by technically qualified and
trained personnel. It is the responsibility of the RTR-4 user to
ensure only trained personnel are permitted to configure, operate,
and maintain RTR-4 equipment. It is the responsibility of the user
to verify that all regulations have been met before operating this
equipment.
Symbols
In procedural steps, specific warnings and cautions are placed
immediately prior to the step(s) to which they apply. Specific
warnings and cautions have three parts:
• The specific hazard is stated.
• The correct action to be followed or performed is given.
• The consequences if the correct action is not followed are
stated.
The following warning symbols and the caution symbol are used
in this manual when warnings and cautions are placed into
procedural steps.

Safety Summary RTR-4 Operator’s Manual
2-2 SAIC Proprietary 120300 Rev. D
Safety Procedures
The X-ray source used with the RTR-4 system generates x-rays
that can be harmful to personnel. It is the responsibility of the
operator to ensure that the RTR-4 is properly used by trained
personnel who follow recommended operating procedures and
SYMBOL DEFINITION OF USE
The generic Warning symbol precedes a procedural
step or process which could lead to personnel injury
if not followed correctly. This symbol is used when
multiple hazard conditions may be present or one of
the symbols below does not specifically apply.
The Electrical, High Voltage, or High Current
hazard warning symbol is used where the potential
for electrical shock may exist while performing a
specific task.
The X-Ray Radiation hazard warning symbol is
used whenever emitted x-ray radiation may exceed
background levels during a specific procedure or
process.
The Microwave Radiation hazard warning
symbol is used whenever emitted microwave/rf
radiation is present during a specific procedure or
process.
The generic Caution symbol precedes a procedural
step or process which could lead to equipment
damage if not followed correctly.
The ESD caution symbol precedes a procedural
step or process requiring use of standard approved
ESD damage control procedures to avoid harming
electronic components and circuit card assemblies.
The Note symbol indicates where additional or
clarifying information, commentary, sidelights, or
points of interest have been added to a procedure
either before or after the step to which it applies.

applicable regulations, and the X-ray Source supplier guidelines,
such as the Golden Engineering XR200 X-Ray Source Operator’s
Manual.
General Safety Procedures
The following are general safety precautions for using X-ray
generating devices:
• As Low As Reasonably Achievable (ALARA) principles of
radiation exposure are applicable whenever the RTR-4 system
is being used. Personnel exposure to X-rays shall be kept to the
absolute minimum possible.
• Users shall establish appropriate exclusion zones to limit
access to the radiation field. This information can be found in
the Users’s Manual for the applicable X-ray source or on the
manufacturer’s webpage. When two or more exclusion zones
apply, such as using the RTR-4 in the presence (or suspected
presence) of explosives, the larger exclusion zone perimeter
shall apply.
• Operating personnel shall review and follow applicable
regulations.
• In order to meet the FCC RF safety regulations when using the
wireless configuration, personnel shall maintain a distance of
at least 20cm (8in) from the WiFi antennas when the system
is operational.
• Personnel in the vicinity when the RTR-4 system is being
operated may be required to wear an approved X-ray radiation
monitoring device in accordance with local regulations or
administrative procedures.
• Personnel shall remain at a safe distance from the X-ray
source, and always remain outside the direct beam during
image acquisition if possible.
• Personnel shall remain at a distance of at least 20cm (7.9in)
from the antennas whenever the RTR-4 wireless option is
being used.
• When using the optional Notebook Safety Lock, the controller
key shall be turned to the OFF position when not acquiring
images. The X-ray source cannot fire when its controller key is
in the OFF position.
• The power key for the X-ray source should be turned to the
OFF position when the system is not acquiring images. The
X-ray Source cannot fire when its key is in the OFF position.

Safety Summary RTR-4 Operator’s Manual
2-4 SAIC Proprietary 120300 Rev. D
• The system operator shall remove the controller key and X-ray
Source keys when not operating the system, to ensure that the
system is not accidentally or improperly operated.
• All reasonable efforts shall be made to reduce doses to ALARA
levels.
Safe Operating Environment
The following environmental conditions affect the safe operating
conditions of the RTR-4:
• Maximum external voltage fluctuation of ± 10%.
• Maximum altitude 2000m (6562ft).
• Operating temperature range 5°C (41°F) to 40°C (104°F).
• Maximum relative humidity of 80%.
Outdoor Use
All parts of the RTR-4 system are intended for the outdoor use
except for the external ac power adapters. If external power
adapters must be used outdoors, ensure they are protected from
adverse weather conditions such as rain or moisture. Failure to
use adequate precautions may result in equipment damage or
personnel hazard.

12Vdc and 24Vdc such as vehicle power.
Image Target Area
The active image area is indicated on the face of the imager. This
is the area that will be displayed on the controller PC.
Orientation Indicator
A triangle in one corner of the image target area is shown as a ball
in a circle on the controller PC image and indicates the lower edge
of the image. This ball is free floating and will always indicate the
downward edge of the image as the imager is positioned on its
sides or other orientations. Rubber feet and standard threaded
tripod mounting holes are provided on three sides to permit
placement of the imager in different orientations.
