3 Basic Operation
48
When disconnected from AC power, the monitor retains the date and time setting for at least two
months. If the monitor is off longer than two months, and the operating system detects that the date
and time settings are invalid, the monitor initiates a "cold" start and sets the date to 1 Jan 1997 and the
time to 00:00.
Checking Your Monitor Revision

2 From the Monitor Revision menu, select the monitor component for which you need revision
information.
Preparing to Monitor
Confirm fetal life before you begin fetal monitoring. Familiarize yourself with the basic operation
principles before you start to monitor.
CAUTION
Check the fetal monitors housing for damage before you start to monitor as part of your safety
precautions.
After you switch on the monitor:
1 Check that you have the correct patient cables and transducers plugged in for the measurement
you want to monitor.
2 If you use an Avalon CL or Avalon CTS system, check if the cableless transducers are ready and
charged (apparent by either a lit up green or yellow LED indicator).
3 Admit your patient to the monitor (see “Admitting a Patient” on page 147).
4 Check that the alarm limits, alarm and fetal heart rate volumes, patient category, and so forth, are
appropriate for your patient. Change the settings if necessary.
5 Refer to the appropriate measurement section for details of how to perform the measurements
you require.
6 Start recording.
