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 theoperator 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.

REGULATORY REQUIREMENTS
This product conforms with the requirements of Council Directive 93/42/EEC concerning med-
ical devices when it bears the following CE marking of conformity:
Note:This equipment generates, uses, and can radiate radio frequency energy. The 
equipment may cause radio frequency interference to other medical and non-medical 
devices and radio communications. To provide reasonable protection against such 
interference, the AMX4+ Mobile X-Ray Unit complies with emissions limits for a Group 
1, Class A Medical Devices as stated in EN 60601-1-2. 
 However, there is no guarantee that interference will not occur in a particular 
installation. If this equipment is found to cause interference (which may be determined 
by switching the equipment on and off), the user (or qualified service personnel) should 
attempt to correct the problem by one or more of the following measure(s):
• Reorient or relocate the affected device(s).
• Increase the separating space between the equipment and the affected device.
• Power the equipment from a source different from that of the affected device.
• Consult the point of purchase or service representative for further suggestions.
The manufacturer is not responsible for any interference caused either by the use of 
interconnect cables other than those recommended, or by unauthorized changes or 
modif ications to this equipment . Unauthorized changes or modif ications could void the users 
authority to operate the equipment .
To comply with the regulations applicable to an electromagnetic interface for a Group 1, Class 
A Medical Device, all interconnect cables to peripheral devices must be shielded and properly 
grounded. Use of cables not properly shielded and grounded may result in the equipment 
causing radio frequency interference in violation of the European Union Medical Device 
directive and FCC regulations.
Setting for Mobile AID
Under certain Electro Static Discharge (ESD) conditions, the optional Automatic Exposure Con-
trol for the AMX 4+ may self-modify its settings. The operator will need to adjust the settings 
to their original condition. If the problem cannot be corrected, please call service.
