1 Introduction
1.1 Brief description
Thank you for purchasing the AccuScreen handheld Otoacoustic Emissions and Automated ABR
Screener.
We also recommend that you take particular note of the cleaning and maintenance instructions.
Failure to use and maintain AccuScreen correctly may void your warranty.
AccuScreen is a fast, reliable, easy to use, and lightweight hearing screener, optimised for
neonatal screening.
AccuScreen provides for easy navigation using its touch screen function.
1 Introduction
Note• This manual is your guide to the use and maintenance of AccuScreen. We strongly
recommend that you read it carefully before using AccuScreen for the first time.
1.2 The docking station
AccuScreen is supplied with a docking station, which provides for:
• easy recharging of the battery
• transferring data between AccuScreen and PC
• printing from a label printer
1.3 The AccuLink software program
AccuLink is a software program providing data management handling with result review and configuration capabilities in a
single PC application.
From AccuLink you can create, edit, view and print data relating to patients and tests, users, sites and connected locations
and facilities.
From AccuLink you can configure AccuScreen to suit your purposes. This includes defining mandatory fields in patient handling, defining which screens are to be shown in AccuScreen, and uploading and downloading data.
AccuScreen is operated independently of AccuLink, although additional features and configuration value are provided by
AccuLink’s user interface.

1 Introduction
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 disorders.
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 results 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.
1.6
Important • Natus Medical Denmark A/S does not guarantee the accuracy of the test results or the tests themselves, if
accessor-ies other than those supplied by Natus Medical Denmark A/S are used for this device (i.e. eartips, electrodes, ear
couplers, etc.).
Physical operating principle
AccuScreen uses TEOAE (Transiently Evoked Otoacoustic Emissions) and DPOAE (Distortion Product Otoacoustic Emissions)
technologies, which are highly effective for neonatal hearing screening. Otoacoustic Emissions measure cochlear mechanics and indicate whether the cochlea is functioning correctly or not.Children's emissions are typically strong, which
makes them easy and fast to detect. Emission strength usually decreases with age or hearing impairment.
Automated ABR (Auditory Brainstem Response) is available in AccuScreen. This technology measures responses to sound
in the auditory pathways. It provides a valuable supplement to TEOAE and DPOAE screening, and is an essential tool for
screening infants with a risk of hearing loss.
The simple yet reliable technology ensures that hearing loss can be detected and that intervention can be implemented
at an early age. With early intervention, hearing-impaired children are given the possibility of developing normal speech
and language skills.

4.1 Preparing AccuScreen
• Follow the instructions in Getting Started with AccuScreen ► 20.
• You can download patient data in advance from the AccuLink database (see the AccuLink User Manual).
• See Testing with AccuScreen ► 36 on how to proceed with the specific tests.
4.2 Preparing the equipment
Every day before you start testing on patients, we recommend that you perform whichever quality tests that may be necessary to make sure that probe, electrode cable and ear coupler cable function correctly. See Quality Tests ► 65.
Caution • Insert only disinfected probe tips in the test cavity. See Cleaning and disinfecting the built-in test cavity ►
85.
4.2.1 Preparing the probe for testing
Inspect the probe for deterioration (colour changes, surface changes) of the reusable probe parts before every usage. If
deterioration occurs, contact your distributor.
4.2.2 Connecting the probe
1. Place AccuScreen face down.
The probe plug sleeve and the colouring around the probe socket are blue.
2. Align the ridges on the plug with the notches in the blue-bordered socket on the top end of AccuScreen.
3. Gently insert the probe plug into the probe socket. The plug does not require force to be inserted properly.

Disconnecting the probe
Caution • Do not pull the plug by the cable when you disconnect the probe. Instead, pull the sleeve of the grey con-
nector.
When disconnecting the plug, do not twist it. Instead, hold the sleeve of the plug and release it by pulling it straight out of
the socket.
The probe will not be released if you pull anywhere else than on the sleeve of the plug.
4.2.3 Connecting the electrode cable for ABR testing
4 Preparing for testing
1. Place AccuScreen face down.
The electrode cable plug sleeve and the colouring around the electrode plug socket on AccuScreen are green.
2. Align the ridge on the electrode cable plug with the notch in the green-bordered socket on the top end of
AccuScreen.
3. Gently insert the electrode cable plug into the electrode cable socket. The plug does not require force to be inserted
properly.
Disconnecting the electrode cable
Caution • Do not pull the plug by the cable when you disconnect the electrode cable. Instead, pull the sleeve of the
grey connector.
When disconnecting the plug, do not twist it. Instead, hold the sleeve of the plug and release it by pulling it straight out of
the socket.
The cable will not be released if you pull anywhere else than on the sleeve of the plug.
4.2.4 Connecting the ear coupler cable for ABR testing
For ABR-measurements you can use either the ear probe or the ear coupler cable with ear couplers. A major advantage in
using the ear coupler cable is that once the test starts, both ears can be tested simultaneously or consecutively. For ABR

measurement, use the ear coupler cable. The main advantage of the ear coupler cable is that you can test both ears at the
same time or in sequence after starting the test.
1. Place AccuScreen face down.
The sleeve on the plug of the ear coupler cable and the colouring around the ear coupler socket are blue.
2. Align the ridges on the plug with the notches in the blue-bordered socket on the top end of AccuScreen.
3. Gently insert the plug into the probe socket. The plug does not require force to be inserted properly.
Disconnecting the cable
Caution • Do not pull the plug by the cable when you disconnect the ear coupler cable. Instead, pull the sleeve of the
grey connector.
When disconnecting the plug, do not twist it. Instead, hold the sleeve of the plug and release it by pulling it straight out of
the socket.
The cable will not be released if you pull anywhere else than on the sleeve of the plug.
4.3 Preparing the test environment
Physical environment
• Make sure that the test environment is as quiet as possible. The quieter the room is, the more accurate and quick
your testing will be.
• Check that testing is not being done under an air conditioner or in front of a fan or ventilator.
• Check that there are no mobile phones in the vicinity, people talking etc.
Hygienic precautions
• Be sure to follow any established infection control procedures for the setting in which you are working.
• Clean probe body, probe cable and probe plug before each patient or if surface is visibly contaminated.
• Clean ABR electrode cable and electrode cable plug before each patient or if surface is visibly contaminated.
• Use a sterile alcohol wipe to clean the surfaces and wait until the probe body, probe cable and probe plug are completely dry.
