Problem Possible Cause/Criteria Action
The O
2
sensor or connection cord is faulty. Replace the faulty O
2
sensor or
connection cord with a new one.
The MP2 board is faulty if the FiO
2
cannot be
measured but the T1 temperature can be measured at
all the multi-parameter sockets or the FiO
2
can be
measured at one of the multi-parameter sockets.
Replace the faulty board with a new
one.
The MP3 board, MP2 board or motherboard is faulty
if the FiO
2
cannot be measured at the No. 3 multi-
parameter socket only.
Replace the MP3 board, MP2 board
or ECG input block with a new
one*.
FiO
2
cannot be
measured.
The MP1 board or MP2 board is faulty if the FiO
2
cannot be measured at the No. 1 and No. 2 multi-
parameter sockets.
Replace the faulty board with a new
one.
The O
2
sensor is faulty. Replace the faulty probe with a new
one.
FiO
2
data on the
screen is wrong.
The MP2 board is faulty if the FiO
2
is wrong but T2
temperature data is not wrong at any multi-parameter
sockets.
Replace the faulty board with a new
one.
The CO
2
sensor or CO
2
adapter is faulty. Replace the faulty CO
2
sensor or
adapter with a new one.
The MP2 board is faulty if the CO
2
cannot be
measured at any multi-parameter sockets or can be
measured at one of them.
Replace the faulty board with a new
one.
The MP3 board, MP2 board or motherboard is faulty
if the CO
2
cannot be measured at the No. 3 multi-
parameter socket only.
Replace the MP3 board, MP2 board
or ECG input block with a new
one*.
CO
2
cannot be
measured.
The MP1 board or MP2 board is faulty if the CO
2
cannot be measured at the No. 1 and No. 2 multi-
parameter sockets.
Replace the faulty board with a new
one.
The CO
2
sensor is faulty. Replace the faulty sensor with a
new one.
CO
2
data on the
screen is wrong.
The CO
2
adapter is faulty. Replace the faulty adapter with a
new one.
The catheter, bath probe, inline sensor or connection
cord is faulty.
Replace the faulty catheter, bath
probe, inline sensor or connection
cord with a new one.
The MP2 board is faulty if the Ti or Tb cannot be
measured at any multi-parameter sockets or the CO
curve does not appear even when any multi-parameter
socket is used.
Replace the faulty board with a new
one.
The MP3 board, MP2 board or motherboard is faulty
if the Ti or Tb cannot be measured at the No. 3 multi-
parameter socket only or the CO curve does not
appear with the No. 3 socket.
Replace the MP3 board, MP2 board
or ECG input block with a new
one*.
CO cannot be
measured. (Injectate
temperature Ti or
blood temperature
Tb cannot be
measured or CO
curve does not
appear.)
The MP1 board or MP2 board is faulty if the Ti or Tb
cannot be measured at the No. 1 and No. 2 multi-
parameter sockets or the CO curve does not appear
with the No. 1 and No. 2 sockets.
Replace the faulty board with a new
one.
The catheter, bath probe or inline sensor is faulty. Replace the faulty catheter, bath
probe or inline sensor with a new
one.
CO data on the
screen is wrong. (Ti
or Tb temperature
data on the screen is
wrong.)
The MP2 board is faulty if the Ti data is wrong but
FiO
2
data can be measured at all the multi-parameter
sockets or Tb data is wrong but thermistor method
respiration can be measured at all the multi-parameter
sockets.
Replace the faulty board with a new
one.
* ECG input block repair kit is required when one of the ECG RESP1 board, ECG RESP2 board, ECG RESP3 board
and motherboard has a failure. Refer to “Board Compatibility” in Section10 “Internal Switch Setting and Board
Compatibility”.
