The bed is discharged. Admit the patient.
The bed is set to temporary discharge. Resume monitoring.
The bedside monitor or the multiple
patient receiver is turned off.
Turn on the bedside monitor or the
multiple patient receiver.
The currently measured lead/label is
different from the lead/label to be
displayed on the screen.
Confirm the setting so that the currently
measured lead/label matches the
lead/label to be displayed on the screen.
The waveform is not selected as the
displayed waveform.
Set the waveform to the displayed
waveform.
The bed is not registered as a
monitored bed.
Register the bed to the monitored bed.
Network is disconnected. Confirm the network connection.
Waveform is not displayed.
The bedside monitor is an 8000 series
bed connected to the network via the
CNS-9301/9302 central monitor.
Several types of waveforms cannot be
displayed on 8000 series bedside
monitors.
The parameter of the numeric data is
not selected as the displayed
parameter.
Set the parameter of the numeric data to
the displayed parameter.
The label of the currently measured
numericdataisdifferentfromthe
label to be displayed.
Confirm the setting so that the label of
the currently measured numeric data
matches the label to be displayed.
Numeric data is not displayed.
A vital alarm occurred in a parameter
that is not set to a displayed
parameter and its numeric data took
the place of a numeric data that is set
to the displayed parameter.
The numeric data of a parameter whose
vital alarm is currently occurring has a
higher priority to be displayed.
Measure the waveform or numeric data.
Confirm the setting so that the currently
measured lead/label matches the
lead/label to be displayed on the screen.
The desired waveform or
numeric data cannot be selected.
The waveform or numeric data is not
measured.
Register the desired parameter on the
Parameters window of the System
Setup. A parameter registered at the
Parameters window of the System Setup
is displayed on setting keys even when
it is not currently measured.
Some waveforms are not
displayed.
Some of the patient waveforms
cannot be displayed on this central
monitor while another central monitor
that is connected to a multiple patient
receiver or a signal exchanger
displays the individual bed screen of
the patient.
Display the All Beds screen at the
central monitor where the patient’s data
is saved.
The desired parameter cannot be
displayed.
The parameter is a parameter that
cannot be displayed.
Refer to Section 15 “Parameter Priority”
for the list of parameters that can be
displayed on the central monitor.
Cannot find a key to freeze a
waveform or relearn ECG.
Those functions are not assigned to
function keys.
Assign these functions to function keys.
