Prepare the equipment
The ideal test environment is a quiet room where lights and other electronic equipment are turned off.
Prepare the baby
The baby should be sleeping or in a quiet and relaxed state. Sucking, blinking, crying or movement may affect testing.
If the baby’s skin is oily or covered in vernix, the electrode placement sites should be cleaned prior to placing the electrodes.
Place surface electrodes using the specified test montage for the selected protocol (mastoid or nape).
Connect the cables from the preamplifier to the respective surface electrodes.
Place the probe or inset earphones in the baby’s ear/s or place the EarCups around the baby’s ears.
Press the Test button
An impedance check will begin. Impedances are indicated by the green/amber dots on the montage picture as well as in numerical format on the screen.
When a dot is amber, it means the impedance is poor (> 40kΩ) for the indicated electrode. Check that the surface electrode and cables are connected correctly. It may be necessary to re-clean the skin or use a conductive gel with the surface electrodes to achieve an acceptable impedance. Testing cannot begin until impedance indictors are green (< 40kΩ).
|PASS result||REFER result||
|When the pass criteria for the test is reached, a is displayed in green above the measurement, indicating the test has PASSED.||
When the pass criteria for the test is not reached within the measurement time, is displayed in amber above the measurement, indicating the test is a REFER.
|If the test is stopped before a PASS or REFER is generated by the system, is displayed above the measurement indicating that the test is INCOMPLETE.|
