Placing And Using The Shoulder Box Or Preamplifier - Interacoustics Titan IMP440 Setup & Installation

For more stable testing, we recommend using an extension cord with a mushroom shaped ear tip. Make sure
that this ear tip inserts completely into the ear canal. Mushroom shaped ear tips allow you to test 'hands free'
from the Titan. This reduces the chance of contact noise disturbing the measurement.
As an indication, the following chart predicts which ear tip size can be used for patients of a certain age.
There are however large individual differences, so before following these guide lines exactly, always
carefully check if the suggested size suits your patient!

Placing and using the Shoulder Box or PreAmplifier

The extension cord with the small shoulder box can be used for impedance and OAE measurements. The
PreAmp is required for ABRIS testing and can also be used with all other modules.
Use the clip on the back of the shoulder box to attach it to the clothing of the patient. For most patients it
may be suitable to attach the shoulder box to the collar of their shirt/blouse. For the PreAmp it may be more
suitable to attach it to the strap which can then be placed around the neck of the parent who is holding the
patient.

The shoulder box button (1) can be used for operating the
Titan during and in between testing.
During PC controlled mode testing, the shoulder box button
(1) can be used to START or STOP testing when a seal is
maintained in the ear.
In between testing, when the probe is out of the ear, pressing
the button will change the selected ear from right to left and
vice versa.
The button (2) on the PreAmp can be used to START or
STOP a test.
