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.

|
2028451-183 |
|
General fault isolation
Power-up self-test
See the MAC 1600 Operator’s Manual, Chapter 2, “Equipment Overview” to verify operation.
On power-up, the system automatically runs an internal self-test. If all tests pass, you will see the start-up screen.
The next screen that appears after the start-up screen depends on the Power up mode selected in System Configuration. The Resting ECG mode is the default Power up mode.
If the equipment is not working properly, ask yourself the following questions.
Is the unit turned on?
Have there been any changes in the use, location, or environment of the equipment that could cause the failure?
Has the equipment hardware or software been modified since last use?
Is operator error the cause of the problem?
Try to repeat the scenario exactly and compare that to the proper operation of the equipment described in the manual.
Is the battery installed?
When connected to the AC wall outlet, does the green AC power light glow?

Troubleshooting: General fault isolation
Poor quality ECGs
Poor quality ECGs can be caused by factors in the environment, inadequate patient preparation, hardware failures related to the acquisition module, lead wires, cables, or problems in the unit.
Visual inspection
A thorough visual inspection of the equipment can save time. Small things— disconnected cables, foreign debris on circuit boards, missing hardware, loose components—can frequently cause symptoms and equipment failures that may appear to be unrelated and difficult to track.
NOTE
|
Take the time to make all the recommended visual checks before starting any |
|
detailed troubleshooting procedures. |

Troubleshooting: Event logging
8.Enable or disable event logging:
Check the Key Event Logging check box to enable writing to the Event Log, or
clear the Key Event Logging check box to disable writing to the Event Log.
9.Select a level of severity to log from the Log Level list:
Select Error to log only errors to the Event Log.
Select Warning to log errors and warnings to the Event Log.
Select Information to log errors, warnings, and information messages to the
Event Log.
10.Press F6 to select Save.
Exporting the event log
1.Repeat steps 1-7 in “Setting Up event logging”.
2.Insert an SD card in SD card slot in back panel as shown in the following figure (with gold contacts up).
3.Press F1 to select Export Log Files.
The current Event Log file, log_0.log, is copied to a log directory on the SD card.
NOTE
The log file can be accessed by inserting the SD card in an SD card reader that is connected to a computer with a Windows operating system and a text editor like Notepad or WordPad. If the Event Log is requested by
GE Service for troubleshooting an issue, the file can be sent as an email attachment.
