10 Trouble shooting
If you should find that your instrument is no longer working properly during
a test run, please check the following points:
10.1 Instrument does not turn on
Verify that the USB cable is connected securely into both the USB box of the
MB 11 hardware as well as the computer USB port.
Verify that the USB port on the PC meets the specifications described in
Section 4.
Verify that the PC is powered on.
10.2 Poor impedance at one or more electrode sites.
Check the contact of the electrode on the skin.
Check that the electrode lead wire is properly and securely connected to the
electrode.
Remove the electrode and prepare the skin again with a skin preparation
product such as Nuprep or an electrode skin prep pad at the site, wipe it off
and then re-apply the electrode to the site.
10.3 High artifact (poor signal quality) during the screening
Check the state of the baby. A quiet, sleeping baby is most conducive to a
high quality screening. Calm the baby with a pacifier if appropriate.
Position the baby so he/she is comfortable and in a way to release any
tension in the neck. A rolled up blanket tucked to support the baby’s back
and in the curve of the next can help to release tension in this area.
Check that the electrodes remain in contact with the skin. If any electrode
has become detached or loosened from contact, press it back into place or
replace it.
Click on the “EEG” checkbox on the measurement window and view the
EEG at the top of the screen. If there is high amplitude noise or cyclical noise
evident in the EEG then there may be electromagnetic interference in the
test environment. You can unplug the PC and any peripherals that are
plugged into a wall outlet (e.g. printer) and run the test on PC battery only
to see if this cleans and quiets the EEG. If this does not resolve the problem,
try moving the system to a different location in the room or into another
room. Try a different electrical outlet.
10.4 Screening result is not progressing
Screening result is not progressing upward toward the Pass criteria/High
refer rate.
