AccuScreen
With AccuScreen you can upload data to AccuLink and print test results from the PC, or you can place AccuScreen in the
docking station and print directly to a label printer connected to the docking station.
1.5
Intended Use
The Type 1077 device is indicated for use in the recording and automated analysis of human physiological data (screening
auditory brainstem responses and/or otoacoustic emissions) necessary for the diagnosis of auditory and hearing-related dis-
orders.
Distortion Product Otoacoustic Emissions and Transient Evoked Otoacoustic Emissions:
The Type 1077 DPOAE module and TEOAE module can be used for patients of all ages, from children to adults, including
infants and geriatric patients. It is especially indicated for use in testing individuals for whom behavioral audiometric res-
ults are deemed unreliable, such as infants, young children, and cognitively impaired adults.
Auditory Brainstem Response:
The Type 1077 ABR module is especially intended for infants from 34 weeks (gestational age) up to 6 months of age.
When the device is used to screen infants, they should be asleep or in a quiet state at the time of screening.
The device is intended for use by audiologists, ENT's and other healthcare professionals.

Otoacoustic

measure
