All packages should be closely examined at time of delivery. If damage is apparent, write “Damage In Shipment” on
ALL copies of the freight or express bill BEFORE delivery is accepted or “signed for” by a GE representative or
hospital receiving agent. Whether noted or concealed, damage MUST be reported to the carrier immediately upon
discovery, or in any event, within 14 days after receipt, and the contents and containers held for inspection by the
carrier.
A transportation company will not pay a claim for damage if an inspection is not requested within this 14 day
period. Call Traffic and Transportation, Milwaukee, WI [phone] or 8*320 1163, or E-mail @MED Claims-
Traffic, immediately after damage is found. At this time be ready to supply name of carrier, delivery date,
consignee name, freight or express bill number, item damaged and extent of damage.

1. Preface
1.1. Publication Conventions
Standardized conventions for representing information is a uniform way of communicating information to a reader
in a consistent manner. Conventions are used so that the reader can easily recognize the actions or decisions that
must be made. There are a number of character and paragraph styles used in this publication to accomplish this task.
Please become familiar with them before proceeding forward.
It’s important that you read and understand hazard statements, and not just ignore them.
1.2. Safety & Hazard Information
Proper product safety labeling allows a person to safely use or service a product. The format and style for safety
communications reflected in this publication represents the harmonization of IEC/ISO 3864 and ANSI Z535
standards.
Within this publication, different paragraph and character styles are used to indicate potential hazards. Paragraph
prefixes, such as hazard, caution, danger and warning, are used to identify important safety information. Text
(Hazard) styles are applied to the paragraph contents that are applicable to each specific safety statement.

1.3. Hazard Messages
Any action that will, could or potentially cause personal injury will be preceded by the safety alert symbol and an
appropriate signal word. The safety alert symbol is the triangle with an exclamation mark within it. It’s always used
next to the signal word to indicate the severity of the hazard. Together, they are used to indicate a hazard exists.
Signal words describe the severity of possible human injures that may be encountered. The alert symbol and signal
word are placed immediately before any paragraph they affect. Safety information includes:
1.) Signal Word - The seriousness level of the hazard.
2.) Symbol or Pictorial - The consequence of interaction with the hazard.
3.) Word Message:
a.) The nature of the hazard (i.e. the type of hazard)
b.) How to avoid the hazard.
The safety alert symbol is not used when an action can only cause equipment damage.
1.4. Text Format of Signal Words
DANGER - INDICATES AN IMMINENTLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED,
WILL RESULT IN DEATH OR SERIOUS INJURY. THIS SIGNAL WORD IS LIMITED TO THE
MOST EXTREME SITUATIONS.
WARNING - INDICATES A POTENTIALLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED,
COULD RESULT IN DEATH OR SERIOUS INJURY.
CAUTION - Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. It may also be used to alert against unsafe practices.
NOTICE - Indicates information or a company policy that relates directly or indirectly to the safety of
personnel or protection of property. This signal word is associated directly with a hazard or hazardous
situation and is used in place of 'DANGER,' 'WARNING,' or 'CAUTION.'
It can include:
•Destruction of a disk drive
•Potential for internal mechanical damage, such as to a X-ray tube

1.5. Symbols and Pictorials Used
The following Symbols and Pictorials are be used in this publication. These graphical icons (symbols) may be used
to make you aware of specific types of hazards that could possibly cause harm.

2. Publication Conventions
2.1. General Paragraph and Character Styles
Prefixes are used to highlight important non-safety related information. Paragraph prefixes (such as Purpose,
Example, Comment or Note) are used to identify important but non-safety related information. Text styles are also
applied to text within each paragraph modified by the specific prefix.
EXAMPLES OF PREFIXES USED FOR GENERAL INFORMATION:
Purpose: Introduces and provides meaning as to the information contained within the chapter, section or subsection
(such as used at the beginning this chapter, for example).
Note: Conveys information that should be considered important to the reader.
Example: Used to make the reader aware that the paragraph(s) that follow are examples of information possibly
stated previously.
Comment: Represents “additional” information that may or may not be relevant to your situation.
2.2. Page Layout
Headers and footers in this publication are designed to allow you to quickly identify your location. The document
part number and revision number appears in every header on every page. The page number appears on the left-hand
side (or right-hand side) of the footer.
An exclamation point in a triangle is used to indicate important information to the user.
Paragraphs preceded by Alphanumeric characters (e.g. numbers) contain information that must be followed in a
specific order.
Paragraphs preceded by a symbol (e.g. bullets) contain information that has no specific order.
2.3. Computer Screen Output/Input Text Character Styles
Within this publication, mono-spaced character styles (fonts) are used to indicate computer text that’s either screen
input and output. Mono-spaced fonts, such courier, are used to indicate text direction. When you type at your
keyboard, you are generating computer input. Occasionally you will see the math operator “greater-than” and “less-
than” symbols used to indicate the start and finish of variable output. When reading text generated by the computer,
you are reading it as computer generated output. In addition to direction, characters are italicized (e.g. italics) to
indicate information specific to your system or site.
Example: Fixed Output
This paragraph’s font represents computer generated screen “fixed” output. Its output is fixed from the sense that it
does not vary from application to application. It’s the most commonly used style used to indicate filenames, paths
and text that do not change from system to system. The character style used is a fixed width such as courier.
Example: Variable Output
This paragraph’s font represents computer screen output that is “variable”. It’s used to represent output that varies
from application to application or system to system. Variable output is sometimes found placed between greater-
than and less-than operators for clarification.
For example: <variable_ouput> or <3.45.120.3>. In both cases, the < and > operators are not part of the actual
input.
Example: Fixed Input
This paragraph’s font represents fixed input. It’s computer input that is typed-in via the keyboard. Typed
input that does not vary from application to application or system to system. Fixed text the user is required to
supply as input. For example: cd /usr/3p

DIRECTION 5123449-100, REVISION 12
_____________________________________________________________________________________________
June 2009 Page 15 / 111
Example: Variable Input
This paragraph’s font represents computer input that can vary from application to application or system to
system. With variable text, the user is required to supply system dependent input or information. Variable input
sometimes is placed between greater-than and less-than operators.
For example: <variable_input>. In these cases, the (<>) operators would be dropped prior to input.
For example: ypcat hosts | grep <3.45.120.3> would be typed into the computer as: ypcat hosts | grep
3.45.120.3
without the greater-than and less-than operators.
2.4. Buttons, Switches and Keyboard Inputs (Hard & Soft Keys)
Different character styles are used to indicate actions requiring the reader to press either a hard or soft button, switch
or key. Physical hardware, such as buttons and switches, are called hard keys because they are hard-wired or
mechanical in nature. A keyboard or on/off switch would be a hard key. Software or computer generated buttons are
called soft keys because they are software generated. Software driven menu buttons are an example of such keys.
Soft and hard keys are represented differently in this publication.
Example: Hard Keys
A power switch ON/OFF or a keyboard key like ENTER is indicated by applying a character style
that uses both over and under-lined bold text that is bold. This is a hard key.
Example: Soft Keys
Whereas the computer MENU button that you would click with your mouse or touch with your hand
uses over and under-lined regular text. This is a soft key.

3. Introduction
3.1. Objective and Scope of Pre-Installation
This document is intended as a guide and informational resource for planning and properly preparing a location for
the installation of a Precision RXi R&F system. This document is intended to assist the customer and installer in
properly preparing a site for product installation.
3.2. Avoiding Unnecessary Expenses and Delays
To avoid unnecessary expenses and delays, use the “Pre-Installation” checklist located in “Chapter 7”to determine
if you are ready for the installation to begin. Once you believe that your room/location is ready for installation to
begin, complete the “Pre-Installation” checklist. The checklist is an important tool that helps verify that nothing has
been missed. The checklists summarizes the preparations and allows you to record a permanent record of the
activities that have taken place.
3.3. An Overview of the Pre-Installation Process
Pre-installation is a co-operative effort between the customer/purchaser and GE Medical Systems (GEMS). Figure

4.1.4. Magnetic/Electrical Field Sensitivity and Electromagnetic Emissions
All the products or components of the Precision RXi R&F system meet EMI and EMC requirements 46-319024 and
IEC 601-1-2 (International). Because X-ray equipment produces radiation, special precautions may need to be taken
or special site modifications may be required. GE Medical Systems does not make recommendations regarding
radiation protection. It is the purchasers responsibility to consult a radiation physicist for advice on radiation
protection in X-ray rooms.
4.2. Structural
4.2.1. Door Size Requirements
Note: Door widths are based on a “straight-in” approach requiring an 8 ft. (2.44 m) wide corridor.
Calculations need to be made for accommodation of equipment through narrower corridors.
Minimum door sizes also apply to hallways and elevators. See Chapter 7 - Planning Aids, for additional details.
