Preparing for Testing Echo-Screen III Pro Instructions for Use
4 Press gently and firmly to adhere the hydrogel surface to the skin, and hold in place for a
few seconds to create a good adhesion to the patient's skin.
Note: To help reduce interference during testing, make sure that the ATA cable
does not touch the electrodes during testing.
IMPORTANT: Always handle the electrodes only by the non-adhesive tab. The adhesive
surface is conductive and may become unusable with excessive or improper handling.
Apply disposable earphones if using ATA cable for ABR screenings:
1 Open the earphone pouch by tearing the notch in the corner. Leaving the earphones on the
liner, attach the earphones to the earphone connectors on the transducer housings.
IMPORTANT: Flexicoupler earphones are designed for single-patient use. Do not reuse.
Note: Flexicoupler earphones are designed only for use with newborn patients.
Note: Flexicoupler earphones are intended only for use with the ATA cable. Do
not attempt to use Flexicoupler earphones with the OAE cable.
2 One at a time, remove an earphone from the liner and place it over the patient's ear:
Blue transducer — left ear Red transducer — right ear
Position the earphone tab at the back of the ear with the cable emerging either toward the
top of the head or toward the patient's body. Roll the earphone from the back of the ear to
the front as you attach it to the patient.
WARNING Any use of the earphones or the earphone cable other than described here may
result in screening at unknown and uncontrolled decibel levels.
Never apply pressure to the ear canal or compress the tragus (the prominence in
front of the external opening of the ear).
Never insert the acoustic transducers directly into an ear.
