1 Introduction
1.1 MADSEN OTOflex 100
MADSEN OTOflex 100 is a compact and portable wireless immittance test device.
It offers a complete range of capabilities for middle ear diagnostics. MADSEN OTOflex 100 can be
operated anywhere as a stand-alone device or operated directly from OTOsuite.
MADSEN OTOflex 100 integrates closely with the OTOsuite Immittance module, with full test control from both the device and OTOsuite. When used with OTOsuite, you gain additional features
and diagnostic value offered by the comprehensive user interface and NOAH compatibility of OTOsuite.
MADSEN OTOflex 100 - OTOsuite interfacing
MADSEN OTOflex 100 is designed to operate with the OTOsuite Immittance module.
Bluetooth
MADSEN OTOflex 100 connects with OTOsuite via BluetoothTM, which provides wireless connection between MADSEN
OTOflex 100 and OTOsuite up to a range of approximately 10 metres (approx. 33 ft), and up to a range of 100 metres
(approx. 330 ft) for other electronic devices.
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 OTOflex 100 test results can be stored in the NOAH database via OTOsuite.
1.2 The OTOsuite Immittance module
The OTOsuite Immittance module offers real time presentation of test results
and full test control of MADSEN OTOflex 100 directly from a PC. Test devices
with integrated user interfaces can be operated independently of the Immittance module, although additional features and diagnostic value is 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 basic Immittance module functions are described in Navigating in the OTOsuite Immittance module ► 36.
The OTOsuite Immittance module lets you work with NOAH or save and view results via XML files. The OTOsuite Immittance module supports
• screening and diagnostic tympanometry
• Reflex Threshold testing
• Reflex Decay testing
• ETF-P
• user-defined tests.

1 Introduction
MADSEN OTOflex 100 - OTOsuite interfacing
MADSEN OTOflex 100 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 OTOflex 100 and the Immittance module, you can
• view and print test results,
• view the progression of a range of tests online,
• view historic tympanometry results from NOAH or XML,
• view online tympanometry results during testing,
• perform “over the rim” testing, using the audiometer as a handy control panel while you follow stimulus settings and
test progress on your PC display,
• upload test results from offline tests.
1.3 Intended use
MADSEN OTOflex 100 and the Immittance module
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 OTOflex 100 uses technologies which are highly effective for clinical and screening purposes. Tympanometry and
acoustic 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.
The MADSEN OTOflex 100 probe is extremely lightweight (only 4.5 grams), and comes with comfortable, easy to insert eartips. This makes it ideal for use with children and adults.
MADSEN OTOflex 100 can be configured for a wide variety of tests, and it can be operated entirely manually or programmed for the user’s own combination of manual and automatic operation. In user-programmable tests the user can
select the default parameters of a particular test, and combine tests to form a sequence of preset tests.
1.4 About this manual
This is your guide to using MADSEN OTOflex 100 and the OTOsuite Immittance module. It also introduces you to the key
features 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 OTOflex 100 and how it operates with
OTOsuite 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.

MADSEN OTOflex 100 is powered by batteries.
Caution• Use only the battery types listed in Technical specifications ► 176.
18 Otometrics - MADSEN OTOflex 100
See Batteries ► 19.
Power-related settings
You can customize the various power-related settings in MADSEN OTOflex 100 to suit your purposes and save power and
batteries. See Device settings ► 129.
3.4.2 Powering the charger
Charger
The MADSEN OTOflex 100 charger is connected to the electrical power outlet.
It is recommended that you leave MADSEN OTOflex 100 in the charger when not in use. This ensures that the device is
always ready for testing.
Connecting the charger to the mains power outlet
Warning• Operating at the wrong voltage may blow the fuses!See the label on the charger for input voltage.
1. Before you connect the power cable to the charger, make sure that the
voltage from the electrical power outlet matches the voltage shown on
the identification label on the charger.
2. Connect the charger to the mains power outlet. The device is
delivered preset for rechargeable NiMH batteries.
3. When you are not using the device, leave it in the charger so that it is
always ready for testing.
3 Installing MADSEN OTOflex 100
Warning• If you use the device with Alkaline batteries, always
switch off the mains power supply to the charger. Failure to do so
may cause the Alkaline batteries to leak and cause damage to the
device.
3.4.3 Batteries
Note•Do not insert the battery cover in the battery compartment if the battery compartment is empty. If you do,
the cover will lock in place inside the device.
Caution• Use only the battery types listed in Technical specifications ► 176.
MADSEN OTOflex 100 checks the battery type when you switch it on or place it in the charger, and will prompt you for
the battery type if it seems to be wrongly configured.
If this is the case, change the battery type setting in the device to reflect the battery type you have inserted. See Battery
type setting ► 21.
