3.5 Patient preparation prior to testing
Prior to testing the patient must be informed about the procedure of the test, the ear canal should be
examined, the skin must be prepared for the placement of the electrodes, and the surface electrodes must
be mounted on patient.
All sockets on the cable collector that is connected to the preamplifier must have an electrode cable plugged
in and be connected to the patient via electrodes.
If a socket is left open or a cable not connected to the patient via an electrode, rejection will occur and
testing will not be possible. Both the ipsilateral and contralateral EEG is evaluated to determine rejection.
Risk of strangulation.
Keep cables away from baby’s neck
Avoid contact between the unused electrodes and any other conductive
parts
3.5.1 Impedance check
Pre
ss the Imp. button and
turn the dial fully
clockwise.
Tu
rn the dial slowly
counter clockwise.
T
he LED for each
electrode will change
from red to green as
the impedance is found
for each electrode.
Pre
ss the Imp. button to exit
the impedance mode
before testing.
3.5.2 Transducers
Prior to testing the intended transducers for the measurement must be placed correctly on the patient.
The insert phone and headphone delay has been compensated for within the software, so time 0ms on the
time scale equals the acoustic presentation. Therefore, the waveform latencies on the test screen are the
true latencies comparable across the transducers.
Further information about test preparation can be obtained from Eclipse Additional Information Manual.
