STATUS M ESSAGES
VF8 DELTA/DELTA XL/KAPPA 25-9
— Replace the sensor, if it continues to fail.
*** - if an electrode is not making contact (off) or if an electrode's impedance
value is high or clipping. In this case, press on the electrode to improve
contact and make sure its impedance value is within limits.
Status Messages
NOTE: The fourth electrode's impedance value and status are blank if a sensor with
three electrodes (for example, a pediatric sensor) is used.
Message Possible Cause Suggested Action
BIS: Pod Initializing The BISx pod is initializing
and performing a self-test.
Wait until the initialization is completed.
BIS: Sensor
impedance check in
progress
The BISx pod is performing a
sensor impedance check.
• Wait until the impedance check is
completed.
• Cancel and retry.
BIS: Sensor check
failed
• The BISx pod failed the
sensor impedance check.
• Defective sensor cable.
• Retry the impedance check.
• Re-prep the electrodes and retry the
impedance check.
• Replace the sensor, if necessary, and
perform a manual impedance check.
• Replace the sensor cable.
BIS > UL
BIS < LL
The BIS parameter value is
above higher/below lower
alarm limit.
• Check the patient and treat, if
necessary.
• Change the alarm limits as
appropriate.
BIS: EMG Out of
Range (High)
The EMG parameter value is
out of range high.
• Check the sensor.
• Isolate the patient from auxiliary
equipment, if necessary.
• Isolate the patient from extraneous
movement or vibration.
• Check the patient and treat, if
necessary.
BIS: PWR Out of
Range (High/Low)
The PWR parameter value is
out of range high/low.
BIS: BCT Out of
Range (High)
BCT parameter value out of
range high/low.
BIS: Signal quality
poor, SQI < 50%
• Artifact caused by motion or
eye blinks.
• Interference from electro-
surgical unit.
• Electrode loosened from
patient.
• Check the sensor.
• Isolate the patient from extraneous
movement or vibration.
• Isolate the patient from auxiliary
equipment, if necessary.
• Re-prep the patient.
BIS: SQI too low,
(SQI value < 15%)
BIS: Sensor
unplugged
• Sensor malfunctioning or
disconnected.
• Defective sensor cable.
• Check the cables and connections.
• Replace the sensor, if necessary.
• Replace the sensor cable.
