Acquisition PCB symptoms
Symptoms relative to patient signal acquisition such as missing
parameter text and waveform(s) may be associated with acquisition PCB
failure. It is important that you are able to distinguish the difference
between the general format of the display, which is generated by the
processor PCB, versus the patient signals and data that is associated
with these patient signals, a function of data acquisition, which is
generated by the acquisition PCB.
Processor PCB symptoms
Symptoms with battery operation, network communications,
asynchronous communications, NBP control, PCMCIA communications,
analog output, audio/sound generation, and video signals as well as other
display-related problems all may be associated with processor PCB
failure. All of these are functions controlled by microcontroller or
graphics processing circuitry located on the Processor/Power
Management PCB.
Network connector
No network connection when a
network cable is connected to the
patient monitor’s Network Connector.
 The Dash patient monitor is
connected to a Dash Port 2 docking
station. The patient monitor’s
Network Connector is inactive when
it is connected to the docking
station.
 Network is disabled in boot code.
 Connect the network cable to the docking station’s
internet connector.
 Enable network in boot code.
 The Dash patient monitor does not
have the optional CARESCAPE
Network option enabled.
 Purchase and enable the CARESCAPE Network
option.
Remote control
The remote control does not activate
the display.
 Cable or Autoport to Mport adapter
connections may be loose.
 Restore the connection.
 Remote control needs to be reset.  Disconnect and securely reconnect the remote
control from the patient monitor.
 Remote control is defective.  Replace the remote control with a known good one.
Masimo SET or Nellcor SPO2
Probe or module malfunction
 Five or more consecutive hardware
failures have occurred.
 Review the input error log for Masimo or Nellcor
failure codes.
