The monitor stores trace data, including annotations, for a minimum of 3.5 hours with the software
revision J.3, and for a minimum of 7 hours with the new main board hardware revision A 00.18, in its
internal backup memory. This allows the monitor to recover trace data that would otherwise be lost
under certain circumstances. In the event of the paper running out, this trace recovery data can be
automatically retrieved and printed, or automatically transmitted to an OB TraceVue/IntelliSpace
Perinatal system (LAN connection only), allowing continuity of data.
The fetal trace printed from the trace recovery data contains all data from the real-time trace.
Note that the data in the memory is cleared when a software upgrade is performed.
Only use Philips paper. Using paper other than Philips paper may result in the failure to recover traces.
Recovering Traces on Paper
The monitor is able to recover traces by printing them out at a high speed from the monitor's backup
memory. If the monitor runs out of paper, or if the paper drawer is open, the exact time when this
happens is stored in the backup memory. If the
paper is loaded and the recorder is started, a trace recovery printout of the data recovered from the
backup memory is automatically printed out at high speed (up to 20 mm/s), starting from the time
noted in the backup memory. This ensures that no data is lost. A minimum of one hour of trace
recovery data is available for printing out from the backup memory. When the trace recovery printout
has finished, the recorder automatically switches back to continue recording the current trace at the

stops, and the next recording following a recorder restart will be a normal, real-time trace.
After switching the monitor off and then back on again, or following a power failure, the time of
the backup memory is no longer available to print. The next recording made following a restart of
the recorder is a normal, real-time trace.
The change back to a real-time recording from a trace recovery printout prompts the recording to
