OEC 9900 Elite Operator Manual

Overview This update provides additional information about your OEC 9900 Elite Workstation and C-Arm. The information in this update is provided in addition to the information found in your Operator Manuals and is provided to help you better understand the operation of the system. This update covers a variety of items related to upgrades made to the hardware and software of the Workstation and C-Arm. The information is organized as follows. • Workstation Uninterruptible Power Supply (UPS) • Starting, Shutting Down, and Restarting the System • Startup, Shutdown, Transport Checklists • Updated Workstation Screens and Functions • Workstation Notes, Cautions, and Warnings • C-Arm Notes, Cautions, and Warnings • Workstation and C-Arm Messages • Labels and Icons • Ordering Disposable and Accessory Items Refer to the table of contents for a complete list.

System Compliance The OEC 9900 Elite Workstation Operator Manual and the 9900 Elite C-Arm Operator Manual incorrectly refer to regulation IEC 60601-2-43. The correct regulation is 21 CFR 1020.30 in all instances.

Updated Safety Information Electromagnetic Compatibility Statement This equipment may generate and use radio frequency energy. The equipment must be installed and used according to the manufacturer’s instructions in order to avoid radio frequency interference. If this equipment generates or receives interference do the following to correct the problem: • Verify that the equipment is the cause by turning the system on and off. • In the event of unintended motor actuation, immediately remove power to the equipment. • In the event of unintended X-ray actuation, immediately remove power to the equipment. • Reorient the equipment until the interference stops. • Relocate the equipment with respect to other equipment in the room. • Plug the equipment into a different outlet so that the equipment and the receiver are on different branch circuits. • Use only input/output (I/O) cables supplied by GE OEC Medical Systems, Inc.

Update • Mobile imaging equipment has the potential to emit electromagnetic radiation that may

interfere with the safe operation of other medical equipment. Conversely, other medical equipment, including RF communications equipment, may emit electromagnetic radiation that interferes with the mobile imaging system.

Essential Performance Criteria The system is designed to perform its intended function during normal operation. In the presence of electromagnetic interference some degradation of displayed live video may occur but the system will return to normal operation when the interference is eliminated. Any loss of function will be readily apparent to the operator and will not cause a safety hazard. Electromagnetic interference will not cause permanent damage to the system.

Workstation Uninterruptible Power Supply (UPS) The OEC 9900 Elite Workstation now contains an Uninterruptible Power Supply (UPS). The UPS provides emergency backup power to the Workstation in the event of an unexpected power loss. If power is unexpectedly lost, the UPS allows the system time to save current images and to shutdown normally.

Changes in Workstation Operation The UPS does not change normal operation of the Workstation.

First Time Workstation Setup The first time the Workstation is set up or after an extended time in storage, the batteries in the UPS need several hours to charge before the UPS can be completely effective in case of an unexpected power loss. Charging of the UPS batteries begins automatically when the Workstation is plugged in and does not affect operation of the Workstation. If the Workstation is connected to a compatible C-Arm, the C-Arm could require several hours to charge its batteries after the system is plugged in initially or after an extended period in storage. Note: For more information on C-Arm charging times and requirements, refer to “C-Arm Battery Charging Guidelines” in this update and to the information on powering on and battery charging in the C-Arm Operator Manual.
