2. If the problem persists, replace the
BIS sensor.
BIS Electrode RE
Lead Off
Low
BIS electrode RE falls
off from the patient.
1. Check the contact between BIS
sensor electrode RE and the patient
skin.
2. If the problem persists, replace the
BIS sensor.
BIS Electrode RT
High Imped.
Low
The impedance of BIS
electrode RT is too high.
1. Check the contact between BIS
sensor electrode RT and the patient
skin.
2. If the problem persists, replace the
BIS sensor.
BIS Electrode RT
Lead Off
Low
BIS electrode RT falls
off from the patient.
1. Check the contact between BIS
sensor electrode RT and the patient
skin.
2. If the problem persists, replace the
BIS sensor.
BIS DSC Error Low
A BIS DSC
communication error
occurs.
Replace the BIS module.
BIS DSC Malf Low
BIS DSC malfunctions
and turns off
automatically.
Replace the BIS module.
BIS No Cable Low
The BIS cable is not
connected.
1. Check the BIS cable.
2. If the problem persists, replace the
BIS cable.
BIS No Sensor Low
The BIS sensor is not
connected.
1. Check the BIS sensor.
2. Reinstall the BIS sensor.
BIS Sensor Too Many
Uses
Low
The BIS sensor is
overused.
1. Check if the use times of the BIS
sensor exceed the restricted times (100
times).
2. If the problem persists, replace the
BIS sensor.
BIS SQI<50% Low SQI is low.
1. Check the contact between the BIS
sensor and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS SQI<15% Low
SQI is very low,
prompting the user that
the BIS value is not
reliable.
1. Check the contact between the BIS
sensor and the patient skin.
2. If the problem persists, replace the
BIS sensor.
BIS SQI L<15% Low
SQI L is very low,
prompting the user that
the BIS value is not
reliable.
1. Check the contact between the BIS
sensor and the patient skin.
2. If the problem persists, replace the
BIS sensor.
