Warnings, Precautions for Use, and Relevant Contraindications:

The MAC 3 ECG System is intended for use by trained healthcare professionals for the acquisition and analysis of ECG signals in clinical environments. Prior to use, ensure all electrodes are placed correctly according to standard clinical practice, the device is properly powered, and the acquisition settings are configured to the patient’s clinical needs. Continuous inspection of lead integrity and signal quality is essential for accurate diagnostic results.

Do not use the system in the presence of flammable anesthetic agents or in high-interference environments that may compromise signal accuracy. Interpretation of ECG results should only be performed by qualified clinicians in conjunction with other clinical findings. Always adhere to institutional protocols and manufacturer guidelines to ensure patient safety and optimal device performance.
