Introduction: Safety Messages
General
The intended use of this device is to record ECG signals from surface ECG electrodes. This device can analyze, record, and store electrocardiographic information from adult and pediatric populations. This data can then be computer analyzed with various algorithms such as interpretive ECG and signal averaging for presentation to the user.
This device is intended for use under the direct supervision of a licensed health care practitioner.
Failure on the part of the responsible individual, hospital, or institution using this equipment to implement a satisfactory maintenance schedule may cause undue equipment failure and possible health hazards.
To ensure patient safety, use only parts and accessories manufactured or recommended by GE Healthcare.
Contact GE Healthcare for information before connecting any devices to this equipment that are not recommended in this manual.
If the installation of this equipment, in the USA, will use 240 V rather than 120 V, the source must be a center-tapped, 240 V, single-phase circuit.
Parts and accessories used must meet the requirements of the applicable IEC 60601 series safety standards, and/or the system configuration must meet the requirements of the IEC 60601-1-1 medical electrical systems standard.
The use of ACCESSORY equipment not complying with the equivalent safety requirements of this equipment may lead to a reduced level of safety of the resulting system. Consideration relating to the choice shall include:
use of the accessory in the PATIENT VICINITY; and
evidence that the safety certification of the ACCESSORY has been performed in accordance to the appropriate IEC 60601-1 and/or IEC 60601-1-1 harmonized national standard.

Theory of Operation
Overview / Block Diagram
The MAC 3500 CPU board contains all of the circuitry for the MAC™ 3500 resting ECG analysis system except for the line power supply, acquisition module, keyboard and display. Although the MAC 3500 runs software derived from products based on the Max-1 architecture (running on the C-Exec operating system), it has almost nothing in common with that hardware family. Components listed in this section refer to the 801212-007 CPU board assembly.
The CPU board contains the following:
64 MB SDRAM (holds both code and data)
32 MB SDRAM acts as video frame memory
32 MB NAND Flash (holds FPGA configuration and system code)
32 MB NAND Flash for ECG Record storage
128 KB Boot Data Flash (holds primary boot image)
CRT video DACs
External 12 Volt Power Switch
Acquisition Module Transceiver / Power Switch
Printhead Power Switches and Pixel Test Circuit
Daughter Board Interface which support LAN and modem
