about BIS module
initialization.
2. If the problem persists, replace the
BIS module.
3. If the problem persists, check the
connection cable between the
backplane and the display.
4. If the problem persists, replace the
module rack (refer to 11.1.14).
5. If the problem persists, replace the
cable between the backplane and
display.
BIS Comm Abnormal High
No waveform data
packet is received for
consecutive 2s, or no
data packet of BIS
monitored parameters is
received for consecutive
4s.
1. Re-plug the BIS module, or replace
the slot.
2. If the problem persists, replace the
BIS module.
3. If the problem persists, check the
connection cable between the
backplane and the display.
4. If the problem persists, replace the
module rack (refer to 11.1.14).
5. If the problem persists, replace the
cable between the backplane and
display.
BIS Over Range
Low
The monitored value
exceeds the
measurement range of
the module.
Replace the BIS module.
BIS L Over Range
BIS R Over Range
BIS High Imped. Low
The sensor is not
properly adhered to the
patient skin. The
impedance is too high.
1. Check the contact between the BIS
sensor and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS Sensor Off Low
The sensor falls off from
the patient.
1. Check the contact between the BIS
sensor and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS Electrode 1 High
Imped.
Low
The impedance of BIS
electrode 1 is too high.
1. Check the contact between BIS
sensor electrode 1 and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS Electrode 1 Lead
Off
Low
BIS electrode 1 falls off
from the patient.
1. Check the contact between BIS
sensor electrode 1 and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS Electrode 2 High
Imped.
Low
The impedance of BIS
electrode 2 is too high.
1. Check the contact between BIS
sensor electrode 2 and the patient skin.
2. Replace the BIS sensor.
BIS Electrode 2 Lead
Off
Low
BIS electrode 2 falls off
from the patient.
1. Check the contact between BIS
sensor electrode 2 and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS Electrode 3 High
Imped.
Low
The impedance of BIS
electrode 3 is too high.
1. Check the contact between BIS
sensor electrode 3 and the patient skin.
2. If the problem persists, replace the
