Directions for use Chapter 6 Reference 53
Monitor radio specifications (2.4 GHz)
ECG specifications
The ECG channel meets all the requirements for Cardiac Monitors Heart Rate Meters and
Alarms specified ANSI/AAMI EC13-1992, except for Impulse response at the monitor
(section 3.2.9.8 part (c)), and Standardizing Voltage at the monitor and at Acuity (section
3.2.9.9). The channel also meets the American National Standard, Safe Current Limits for
Electromedical Apparatus (ANSI/AAMI ES1-1993).
