1 Introduction to MADSEN Zodiac
MADSEN Zodiac is a compact device for immittance testing.
MADSEN Zodiac is available both as a Quick Check device and as a diagnostic testing device. Both types can be operated
either directly from the device (Stand-alone), and/or from the OTOsuite Immittance module software (PC-based).

Supported tests
Depending on the configuration, Zodiac supports the following tests and functionalities:
• Tympanometry (Quick Check, Diagnostic, Clinical)
• Reflex Screening (Quick Check, Diagnostic, Clinical)
• Reflex Threshold (Diagnostic, Clinical)
• Reflex Decay (Diagnostic, Clinical)
• ETF-I (Eustachian Tube Function - Intact) (Diagnostic, Clinical)
• ETF-P (Eustachian Tube Function - Perforated) (Clinical)
• Admittance Recording (multiple uses, e.g. patulous Eustachian Tube evaluation, acoustic reflexes with external stim-
ulus) (Diagnostic, Clinical)
• Manual Tympanometry (Diagnostic, Clinical)
• Viewing tympanogram history (Diagnostic, Clinical)
Operating MADSEN Zodiac
•Stand-alone Zodiac
You can operate Zodiac as a stand-alone unit using the built-in keypad and display, or, if you are using the OTOsuite
Otometrics - MADSEN Zodiac 9

Immittance software module, you can operate Zodiac using the PC’s keyboard and mouse with the OTOsuite Immit-
tance module acting as the display.If you are controlling Zodiacfrom OTOsuite, see theMADSEN ZodiacDiagnostic &
ClinicalPC-basedUser Guide.
•PC-based Zodiac
You can operate the PC-based version of Zodiac using the PC’s keyboard and mouse with the OTOsuite Immittance
module acting as the display.
Probes
Depending on the configuration, MADSEN Zodiac supports the following probes:
• The hand-held Quick Check probe: MADSEN ZodiacQuick Check, as well as MADSEN ZodiacDiagnostic and Clinical
• The two diagnostic probe types, Classic and Comfort: MADSEN ZodiacDiagnostic and MADSEN ZodiacClinical
• A contralateral insert phone or TDH-39 supra-aural phone: MADSEN ZodiacDiagnostic and MADSEN ZodiacClinical
MADSEN Zodiac - OTOsuite interfacing
MADSEN Zodiac is designed to operate with the OTOsuite Immittance module. From the OTOsuite Immittance module,
which is NOAH compatible, you can perform tests, monitor test results, create User Tests, store and export data, and print
reports.
Noah
The Noah System is a HIMSA product for managing clients/patients, launching hearing test applications and fitting software,
and storing audiological test results. MADSEN Zodiac test results can be stored in the Noah database via OTOsuite.
Printing test results
Some versions of MADSEN Zodiac have a built-in thermal printer for printing test results. When MADSEN Zodiac is used in
connection with the OTOsuite Immittance software module, test results can be transferred to OTOsuite for printing as
OTOsuite reports.
1.1 The OTOsuite Immittance module
The OTOsuite Immittance module offers real time presentation of test results
and full test control of MADSEN Zodiac directly from a PC. Stand-alone ver-
sions of Zodiac, which have integrated user interfaces, can be operated inde-
pendently of the Immittance module, although additional features and
diagnostic value are offered by the Immittance module's comprehensive user
interface and NOAH compatibility.
When used for testing, the OTOsuite Immittance module adapts to the connected test device. The test functionalities of
the OTOsuite Immittance module depend on the connected device, as does the selection of test parameters and remote
control.
The Immittance module functions are described in Testing with ZodiacDiagnostic or Clinical - PC-based ►86.
The OTOsuite Immittance module lets you work with NOAH or save and view results via XML files.
Supported tests
Depending on the Zodiac connected to OTOsuite, the OTOsuite Immittance module supports the following tests and func-
tionalities:
• Tympanometry (Quick Check, Diagnostic, Clinical)
• Reflex Screening (Quick Check, Diagnostic, Clinical)
10 Otometrics - MADSEN Zodiac

MADSEN Zodiac - OTOsuite interfacing
MADSEN Zodiac is designed to operate with the OTOsuite Immittance module. From the OTOsuite Immittance module,
which is NOAH compatible, you can perform tests, monitor test results, create User Tests, store and export data, and print
reports.
General features
Depending on the configuration of MADSEN Zodiac and the Immittance module, you can
• perform a range of immittance tests
• view the progression of the tests online
• view and print test results
• view historic tympanometry results
• upload test results from tests performed while Zodiac was offline.
1.2 Intended use
MADSEN Zodiac is an auditory impedance tester that is intended to change the air pressure in the external auditory canal
and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the
middle ear. This device is also used to measure the acoustic reflex threshold and decay testing as well as Eustachian tube
function testing for intact and perforated tympanic membranes.
Users: audiologists, ENTs and other health care professionals in testing the hearing of infants, children and adults.
Use: clinical, diagnostic and screening tympanometry and reflex measurements.
MADSEN Zodiac uses technologies which are highly effective for clinical and screening purposes. Tympanometry and acous-
tic reflex measurements measure the mechanical response of the middle ear and form a basis for evaluating whether the
related physiological structures are functioning correctly or not.
Contraindications
Warning •If the patient is troubled by the test, stop the test. The test is interrupted immediately. Already meas-
ured results are kept.
Warning •Look into the ear canal. It is strongly recommended that you perform an otoscopy to assess the status
of the outer ear before you insert the probe. If the ear canal is blocked, this may affect the result of the test.
Otometrics - MADSEN Zodiac 11
1 Introduction to MADSEN Zodiac

Clean the ear canal if needed. Make sure that there is no residual fluid in the patient's ear after cleaning or wax
removal.
Warning •Testing should not be performed on patients displaying the following symptoms without the approval
of a medical doctor:
•If there is discharge in the ear
•If the patient recently has undergone middle ear surgery
•If the ear canal is occluded
•If the patient suffers from acute trauma
•If the patient experiences severe discomfort
•If the patient displays symptoms of tinnitus or hyperacusis, in which case using excessively loud acoustic stimuli
for acoustic reflex measurements should be avoided.
1.3 About this manual
This is your guide to using MADSEN Zodiac and the OTOsuite Immittance module. It also introduces you to the key fea-
tures of the product by providing you with working scenarios for performing tests and viewing and printing test results.
We recommend that you read this manual and make yourself familiar with MADSEN Zodiac and how it operates with OTO-
suite so that you become familiar with the device before testing on a client.
Note •If you are using OTOsuite with Noah, we recommend that you are familiar with the screens and functions
provided in Noah.

2.3 Installing Zodiac
To ensure safe performance of the device, make sure that MADSEN Zodiac is correctly installed and that the requirements
listed as warning notes are complied with.
See Warning notes ►126.
Location
Immittance testing is facilitated by a moderately quiet room. A sound cabin or sound treated room is not necessary.
Wall-mounted installation
If you wish to mount MADSEN Zodiac on the wall, see the instructions supplied with the wall-mount installation kit.
Probe
At delivery, the probe is already connected to MADSEN Zodiac.
This also applies if the configuration includes both a Quick Check probe and a diagnostic probe.
We recommend that you carry out a probe check daily to verify that the system measures correctly.
14 Otometrics - MADSEN Zodiac
2 Unpacking and installation

Note •If the probe check result does not show a value of 1.9 - 2.1 mmho/cc/cm3/ml at 226 Hz, we recommend
that you make an admittance calibration.
Probe home
You can mount the probe home on the wall, using the optional probe home wall-mount kit.
Powering
• See Powering the device ►15.
Connecting to the PC
