Thank you for purchasing AURICAL SpeechLink 100.
SpeechLink 100 is a desktop or wall-mounted advanced 4-channel
frequency analyzer that wirelessly transfers measurement data to a
PC via Bluetooth. The four channels are used for measuring the
sound pressure level close to a client’s eardrum as well as outside
the ear by the pinna for both ears simultaneously. In this way,
SpeechLink 100 enables you to perform true binaural measurements
providing you with valuable information when you adjust Hearing
Instrument settings in the suppliers’ fitting software.
SpeechLink 100 cannot be used without the OTOsuite Visible Speech
Module PC application. When you have set up SpeechLink 100 for
testing, install the relevant software on your PC. When the PC appli-
cation has been installed, run the Configuration Wizard and you will
be able to connect to SpeechLink 100. For specific instructions on
how to use SpeechLink 100 with the OTOsuite Visible Speech Mod-
ule, please see the OTOsuite Visible Speech Module Online Help.
SpeechLink 100 integrates closely with the latest generation of GN
Otometrics test devices by offering real time presentation of test re-
sults and full test control directly from a PC with comprehensive
user interface.

pensers, ENTs, speech therapists and other health care professionals.
The intended use is that the user is able to visualize the amplified
signal recorded in the ear(s) of persons with a hearing loss in order
for the user to have an objective basis for adjusting the Hearing In-
strument settings. Note also that SpeechLink 100 is designed for use
in combination with NOAHlink - HIMSA’s wireless hearing instru-
ment programming device. See Section 2.4.5, ‘Fitting SpeechLink
100 with NOAHlink” on page 23.

OTOsuite Visible Speech Module is designed to operate with AURI-
CAL SpeechLink 100 as the test device (produced by GN Otometrics
A/S.
AURICAL SpeechLink 100 is a compact device, which offers a com-
plete range of test capabilities for Speech Mapping. AURICAL
SpeechLink 100 is controlled directly from the OTOsuite Visible
Speech Module software program.
1.1.3 Bluetooth
SpeechLink 100 connects with the OTOsuite Visible Speech Module
via BluetoothTM. Bluetooth is a wireless communication standard,

without the need for wires or cables to link together the devices. De-
vices can typically communicate at ranges of up to 10 metres (ap-
prox. 33 ft).
