DIAGNOSTICS AND TROUBLESHOOTING
Possible Causes:
No discernible EEG activity
is detected for sixty-three
seconds; SR=100.
Note: This message
notifies user of a flatline
EEG. This is a normal
condition when Sensor
Simulator or Test Sensor is
connected.
The AC power has been lost
and the monitor is running
on the battery. The battery
keeps the monitor operating
for approximately 45
minutes (when the battery is
fully charged).
There are only a few
minutes of battery life left.
Problem is detected relating
to sensor ground element.
Sensor is using too much
current.
Sensor has been connected
and disconnected too many
times.

Corrective Actions:
If unintended:
1. Check patient vital signs,
dosage, etc.
2. Check leads for proper
connection and possible
shorts.
3. Verify Sensor Check
passes.
4. Verify DSC Self Test
passes.
5. Verify PIC. Use Test
Sensor or Sensor Simulator
and Sensor Check.
1. Restore the AC power.
2. Verify power cord.
3. Replace power supply.
Restore AC power to avoid
automatic shutdown.
1. Disconnect and examine
sensor connection. Clean
any contamination present.
2. Replace sensor if necessary.
3. Replace PIC.
4. Replace BISx Bulkhead
Connector or replace BISx.
1. Disconnect and examine
sensor connection. Clean
any contamination.
2. Replace sensor if necessary.
3. Replace PIC.
4. Replace BISx.
Replace the sensor.
