Accessories are intact and properly connected.
•
You have selected desired parameters to be displayed in the digit and waveform fields.
ECG and impedance respiration
•
After connecting ECG cable, check that the message 'Leads off' display in waveform field .
NIBP
•
After connecting NIBP hose, check that the message ‘Adult/Pediatric’ or ‘Neonatal’ will
display in NIBP digital field for several seconds.

Safety checks for software
The GE Healthcare software design controls include performance of a risk analysis using
methods consistent with ISO 14971 Medical devices - Application of risk management to
medical devices.
The monitor software employs watchdog timers, self-monitoring activities (memory,
communication and sensor checks and so on), and power-on self-diagnostics (for example,
memory checksums).
