IMPORTANT! . . . X-RAY PROTECTION
X-ray equipment if not properly
used may cause injury.
Accordingly, the instructions
herein contained should be
thoroughly read and understood
by everyone who will use the
equipment before you attempt to
place this equipment in
operation. The General Electric
Company, Medical Systems
Group, will be glad to assist and
cooperate in placing this
equipment in use.
Although this apparatus
incorporates a high degree of
protection against x-radiation other
than the useful beam, no practical
design of equipment can provide
complete protection. Nor can any
practical design compel the
operator to take adequate
precautions to prevent the
possibility of any persons
carelessly exposing themselves or
others to radiation.
It is important that everyone having
anything to do with x-radiation be
properly trained and fully
acquainted with the
recommendations of the National
Council on Radiation Protection
and Measurements as published in
NCRP Reports available from
NCRP Publications, 7910
Woodmont Avenue, Room 1016,
Bethesda, Maryland 20814, and of
the International Commission on
Radiation Protection, and take
adequate steps to protect against
injury.
The equipment is sold with the
understanding that the General
Electric Company, Medical
Systems Group, its agents, and
representatives have no
responsibility for injury or damage
which may result from improper use
of the equipment.
Various protective material and
devices are available. It is urged
that such materials or devices be
used.
CAUTION: United States Federal
law restricts this device to use by or
on the order of a physician.

Your AMX−4+ is designed for ease of operation and years of reliable service. Each
time you push a button, you can depend on the same consistent radiographic quality −
quality comparable to radiographs made in a full scale x−ray room.
ILLUSTRATION 1−1
Since the AMX−4+ is battery operated, there’s no need to plug in your mobile x−ray
unit before taking exposures. Battery operation makes the AMX−4+ easily adapted
to operating, intensive care, and emergency room applications.
Because of a dual−motor drive, driving and positioning the AMX−4+ requires a
minimum of effort. And the control panel’s cut−away design permits optimum visibil-
ity for steering down crowded corridors.

The self−stopping bumper, one of many built−in safety devices, helps prevent un-
wanted mobility − the motors stop and the brakes activate upon impact with another
object.
Operator controls are microprocessor based, combining the latest technology with
simplicity of design.
The control panel includes three illuminated displays: a kVp and mAs display to re-
flect the technique selected, a battery display for at−a−glance battery status, and a
message display to provide helpful information on the operating status of the
AMX−4+ .

1−2 How to Use This Book
Most sections of your operator manual (see Contents) are organized using two head-
ings:
DOverview, and
DSteps
Overview
Overview, as the name implies, presents general information on a particular operation.
Introductory in nature, the overview is intended to help give you an overall under-
standing of a procedure or capability, quickly and easily.
The word overview is flagged in bold text, like this ...
Overview
and appears in the left margin of the page.
Steps
For specific, detailed information in step−by−step sequence, you’ll refer to the actual
procedure. In this manual, we refer to procedures as steps.
The word steps is flagged in bold text, like this ...
Steps
and also appears in the left margin of the page.
Steps are listed numerically. Any supplemental information (that is, additional infor-
mation you should know, but information that isn’t really necessary to perform the
procedure) is listed under the step in a bulleted Dformat.
Dsupplemental information is placed next to a bullet

We think you’ll find the AMX−4+ portable design performs so easily that it seems to
nearly run itself.
To promote optimum operation of this or any radiographic equipment, however, be
sure to read your operator’s manual carefully.
And, when not in use, store your manual in the cassette tray so that all new users can
easily refer to it when needed.

SECTION 2
SAFETY FIRST
This equipment is to be used by authorized medical personnel only.
Your AMX−4+ is engineered for years of reliable service. To promote optimum
safety, be sure to read this manual carefully, before operating the unit.
Keep the manual with the equipment at all times. When not in use, store it in the
AMX−4+ cassette tray.
Always be alert to safety when you operate this equipment. You must be
familiar enough with the equipment to recognize any malfunctions that can
be a hazard. If a malfunction occurs or a safety problem is known to exist,
isolate the unit to avoid unauthorized operation, and do not use this
equipment until qualified personnel correct the problem.
THIS X−RAY UNIT MAY BE DANGEROUS TO PATIENT AND
OPERATOR UNLESS CORRECT EXPOSURE FACTORS AND
OPERATING INSTRUCTIONS ARE OBSERVED.
ALWAYS PROVIDE NECESSARY RADIATION PROTECTION FOR
YOUR PATIENT AND YOURSELF WHEN OPERATING ANY X−RAY
SYSTEM.
2−1 Good Operating Practices
DWear a lead apron while performing an x−ray exam.
DStep back at least 6 feet (1.8 meters) from the tube or to the full extension of the
handswitch cord before making an exposure.
DAlways use the proper field sizes and technic factors for each procedure to mini-
mize x−ray exposure and produce the best diagnostic results.
DCheck the digital display carefully before making an exposure: verify that the se-
lected technique is the intended technique. Pay particular attention to the place-
ment of the decimal point in the mAs setting to insure that whole numbers are
not mistaken for an intended mAs fractional number.
DWhen x−raying bed patients, move them as far as possible from nearby patients.
DAsk visitors to step outside the room during an exposure.
DUse gonadal shields for patients whenever possible.
DBe sure to read and follow the maintenance schedule outlined in the Maintenance
and Service section of this manual.

DUnder most conditions, cumulative radiation dose to the operator will not ex-
ceed recommended maximum permissible levels. However, as with all radia-
tion−producing devices, a qualified radiation expert should evaluate situations
involving frequent exposures using high kVp and mAs technics to determine if
extra protective devices are necessary.
While driving the AMX−4+, keep the film bin closed. A loaded bin may close
without warning possibly causing injury.
