Interacoustics Eclipse EP25 - Mounting Electrodes for ASSR; ASSR Impedance Check

9.4 Mounting electrodes
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.
9.5 Impedance check
Press the Imp. button
and turn the dial fully
clockwise.
Turn the dial slowly
counter clockwise.
The LED for each
electrode will change
from red to green as
the impedance is
found for each
electrode.
Press the Imp. button
to exit the impedance
mode before testing.
9.6 System performance / loop back (LBK15) testing
The LBK15 unit is not valid for performing a functional check of the ASSR due to the nature of the ASSR
algorithm. For functional testing (detection of false passes), a patient must be connected with electrodes, in
the absence of a stimulus (disconnected transducer).
