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.

CERTIFIED ELECTRICAL CONTRACTOR STATEMENT All electrical installations that are preliminary to positioning of the equipment at the site prepared for the equipment shall be performed by licensed electrical contractors. In addition, electrical feeds into the Power Distribution Unit shall be performed by licensed electrical contractors. Other connections between pieces of electrical equipment, calibrations, and testing shall be performed by qualified GE Medical personnel. The products involved (and the accompanying electrical installations) are highly sophisticated, and special engineering competence is required. In performing all electrical work on these products, GE will use its own specially trained field engineers. All of GE’s electrical work on these products will comply with the requirements of the applicable electrical codes. The purchaser of GE equipment shall only utilize qualified personnel (i.e., GE’s field engineers, personnel of third-party service companies with equivalent training, or licensed electricians) to perform electrical servicing on the equipment.
DAMAGE IN TRANSPORTATION All packages should be closely examined at time of delivery. If damage is apparent, have notation “damage in shipment” written on all copies of the freight or express bill before delivery is accepted or “signed for” by a General Electric representative or a 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 (414) 827−3449 / 8*285−3449 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. Complete instructions regarding claim procedure are found in Section “S” of the Policy & Procedure Bulletins.

General The AMX−4+ contains operating safeguards providing maximum safety. Before servicing, be certain proper operating procedures are being used. Refer to Direction 2166911−100, AMX−4+ Operation, or Direction 2166913−100, AMX−4+ International Operation, for proper operating procedures. Satisfactory equipment performance requires the use of service personnel specially trained on x−ray apparatus. GE Medical Systems, is responsible for the effects on safety, reliability, and performance only if the following conditions are met:
CAUTION
The electrical wiring of the relevant rooms complies with all national and local codes.
All assembly operations, extensions, re−adjustments, modifications, or repairs are carried out by GE Medical Systems, authorized service representatives.
The equipment is used in accordance with the instructions for use. Refer to Direction 2166911−100, AMX−4+ Operation, or Direction 2166913−100, AMX−4+ International Operation, for proper operating procedures. Only trained and qualified personnel should be permitted access to the internal parts of this equipment.

Component Identification See Illustration 1−2. The Cassette Storage Drawer must be opened to change the Service switch to its calibration position. X−ray exposures are made with the X−ray Hand Switch. When making x−ray exposures, move the X−ray Tube and Collimator to the bottom of the Tube Support Column. Take adequate precautions to prevent the possibility of any persons carelessly, unwisely, or unknowingly exposing themselves or others to radiation. Entering calibration commands and selecting procedures is done at the Operator’s Panel.

See Illustration 1−3. Calibration menu selections, prompts, and error codes appear on the Message Display. Values appear on the kVp and mAs Display. Four switches control calibration:
Pressing kVp
(kVp up) displays next menu item, or increases a value.
Pressing kVp
(kVp down) displays previous menu item, or decreases a value.
Pressing mAs (mAs up) exits selection, or continues after display of a prompt for installation or removal of test equipment. It also continues after display of an error condition.
Pressing mAs
(mAs down) executes selection, or saves a value.

Power−up Sequence See Illustration 1−4. Power−up sequence starts either when power is applied, or the microprocessor reset switch is pressed. The service program starts when the service switch is closed before power up. With the service switch closed, the power−up program stops only when an error is found that prevents the calibration program from operating properly. Normally it completes testing, then activates the service program bypassing application programs.

SECTION 2 ENTERING CALIBRATION 2-1
Start Service Program The service program must be entered before calibration can be used. The service program starts when the service switch is closed before power up. Start the service program by: 1. See Illustration 2−1. Set the service switch down to the service position. 2. Reset the AMX−4+ using one of the following methods.
If power is off, turn the Key Switch to the on position.
If power is on and the top cover is installed, turn the power key off and back on.
If power is on and the top cover is removed, providing access to the processor board, press the processor reset switch (AMX1 A2 A1−S183).
When the service program is ready, menu selection END SERVC MODE appears on the Message Display. ILLUSTRATION 2−1 SERVICE SWITCH LOCATION
