1.1
Intended Use
The Titan with IMP440 Impedance System is an electroacoustic test instrument that produces
controlled levels of test tones and signals intended for use in conduction diagnostic hearing
evaluations and assisting in the diagnosis of possible otologic disorders, It features tympanometry
and acoustics reflex. The target population for Titan with IMP440 includes all ages.
The Titan with DPOAE440 is intended for use in the audiologic evaluation and documentation of
ear disorders using Distortion Product Otoacoustic Emissions. The target population for Titan with
DPOAE440 includes all ages.
The Titan with ABRIS440 is intended for use in the audiologic evaluation and documentation of ear
and nerve disorders using auditory evoked potentials from the inner ear, the auditory nerve and the
brainstem. The target population for Titan with ABRIS440 is newborns.
1.1.1
Typical Applications
Titan is well suited for screening, as well as
diagnostic work. Newborn screening
programs will particularly appreciate the
Automated Auditory Brainstem Response
(AABR) test implemented under the ABRIS
module and the option to create user
defined PASS/REFER protocols for DPOAE
screening. The presence of the 1000Hz
probe tone for tympanometry also allows
more reliable tympanometry results in
infants.
Titan, as a screener, will typically be
operated as a hand held device. Results
can be printed using the (Bluetooth) thermal
printer or a Bluetooth PC printer. Optionally,
measurements can be transferred later to a
database on your PC for printing.
In combination with the cradle and shoulder
box for IMP440 and DPOAE440, the Titan
gives you more flexibility in placing the
probe. Choice of ear, start and stop of the
measurement can be controlled from the
shoulder box.
In combination with the Preamplifier (PreAmp), the Titan is capable of performing the full range of
tests from the ABRIS440, DPOAE440 and IMP440 modules.
The Titan, when licensed with a diagnostic or clinical version of the IMP440 or DPOAE440
software, is generally operated via the PC. PC operation allows access to advanced testing
parameters, for example, it permits manual pressure control within the impedance module and the
ability to add extra test points in DPOAE after testing. Testing is as quick in PC controlled mode as
when using the handheld device. Results are saved in your database and can be printed on an
external printer. Protocols can be modified with all the flexibility you need.

Safety Notes
WARNING indicates a hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION, used with the safety alert symbol, indicates a hazardous
situation which, if not avoided, could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.
It is recommended that all staff working with the Titan read this manual and thereby learn the
precautionary measures.
1. External equipment intended for connection to signal input, signal output or other
connector, shall comply with the relevant IEC standard (e.g. IEC 60950 for IT equipment
and the IEC 60601 series for medical electrical equipment). In addition, all such
combinations - systems - shall comply with the standard 60601-1-1, Safety requirements
for medical electrical systems. Equipment not complying with IEC 60601 shall be kept
outside the patient environment, as defined in the standard (at least 1.5 m from the
patient).
2. Any person who connects external equipment to signal input, signal output or other
connectors has created a system and is therefore responsible for the system complying
with the requirements of IEC 60601-1-1. If in doubt, contact your service technician or local
representative for help.
3. In order to comply with IEC 60601, use of the direct power adapter to mains for the thermal
printer when it is connected to the cradle is not permitted. The cradle connection provides
power for the thermal printer.
4. In order to maintain a high level of safety it is necessary to have the instrument and its
power supply checked according to the medical electrical safety standard IEC 60601-1 on
a yearly basis by a qualified service technician.
1. Use this device only as described in this manual.
2. Use only the disposable Interacoustics ear tips designed for use with this instrument.
3. Never insert the probe tip into the ear canal without affixing an ear tip as omission may
damage the patient’s ear canal.
4. Keep the box of ear tips outside the reach of the patient.
5. Be sure to insert the probe tip in a way which will assure an airtight fit without causing any
harm to the patient. Use of a correct and clean ear tip is mandatory.
Titan
Setup and Installation Manual
Page 2
6. Be sure to use only stimulation intensities acceptable to the patient.
7. When presenting contralateral stimuli using the insert phones – do not insert the phones or
in any way try to conduct measurements, without a correct insert ear tip in place.
8. When presenting contralateral stimuli using headphones – do not try to conduct
measurements without the MX41 cushion in place.
9. Clean the headphone cushion regularly using a recognized disinfectant.
10. We recommend using a new ear tip for each patient.
1. Careful handling of the instrument whenever in contact with a patient should be given high
priority. Calm and stable positioning while testing is preferred for optimal accuracy.
2. The Titan should be operated in a quiet environment, so that measurements are not
influenced by outside acoustic noises. This may be determined by an appropriately skilled
person trained in acoustics. OSHA defines a quiet room for audiometric hearing testing in
its guideline OSHA 29 CFR 1910.95.
3. It is recommended that the instrument be operated within an ambient temperature range of
15°C / 59°F – 35°C / 95°F.
4. Storage in temperatures below 0°C /32°F and above 50°C /122°F may cause permanent
damage to the instrument and its accessories.
5. The headphone and insert phone are calibrated to the shoulder box of this instrument –
introducing transducers from other equipment requires a re-calibration.
6. Never clean the transducer housing with water or insert non-specified instruments into the
transducer.
7. Do not drop and avoid other undue impact to this device. If the instrument is dropped or
otherwise damaged, return it to the manufacturer for repair and/or calibration. Do not use
the instrument if any damage is suspected.
8. Although the instrument fulfils the relevant EMC requirements, precautions should be taken
to avoid unnecessary exposure to electromagnetic fields, e.g. from mobile phones etc. If
the device is used adjacent to other equipment, caution must be taken to observe that no
mutual disturbance appears.
9. The temperature of the battery pack in the thermal printer will rise if it is powered through
both the printer’s power supply and through the RJ12 cable to the cradle. Use either one or
the other power connections, but never both, as this may severely reduce the lifetime of
the battery.
10. The connectors marked with the symbol shown below should not be touched without taking
necessary ESD (electrostatic discharge) precautions.
11. The best way to protect the Titan from ESD is to avoid the build-up of electrostatic charges
through the use of conductive footwear and floor coverings. Humidification of the air is also
an effective preventive means. Failing to comply with these measures can cause the buildup of voltage levels of several thousand volts. If the Titan is subjected to such an ESD
pulse, it may be necessary to remove the battery for a few seconds and then restart the
instrument.

General Maintenance Procedures
The performance and safety of the instrument will be maintained if the following recommendations
for care and maintenance are observed:
1
It is recommended that the instrument go through at least one annual service, to ensure that
the acoustical, electrical and mechanical properties are correct. This should be carried out by
an authorized repairer in order to guarantee proper service and repair.
2
Before connection to the mains network, be sure that the local mains voltage corresponds to
the voltage labeled on the instrument. Always disconnect the power cord if the instrument is to
be opened for inspection.
3
Observe that no damage is present to the insulation of the mains cable or the connectors and
that it is not exposed to any kind of mechanical load that could involve damage.
4
For maximum electrical safety, turn off the power from a mains powered instrument when it is
left unused.
5
Do not place the instrument next to a heat source of any kind, and allow sufficient space
around the instrument to ensure proper ventilation.
6
To ensure that the reliability of the instrument is maintained, we recommend that the operator
at short intervals, for instance once a day, performs a test on a person with known data. This
person could be the operator.
7
If the surface of the instrument or parts of it are contaminated, it can be cleaned using a soft
cloth moistened with a mild solution of water and detergent or similar. The use of organic
solvents and aromatic oils must be avoided. Always disconnect the mains power adaptor and
battery during the cleaning process, and be careful that no fluid enters the inside of the
instrument or accessories.
8
After each patient examination, ensure that there has been no contamination to the parts
touching the patient. General precautions must be observed in order to avoid crosscontamination of disease from one patient to another. If ear cushions or ear tips are
contaminated, it is strongly recommended to remove them from the transducer before they are
cleaned. Water should be used for frequent cleaning, but in the case of severe contamination
it may be necessary to use a disinfectant. The use of organic solvents and aromatic oils must
be avoided.
9
Great care should be exercise when handling transducers, as rough handling, for example
dropping onto a hard surface may break or damage the parts.
1.5
Unpacking and Inspection
Check the box and its contents for damage
When the instrument is received, please check the shipping box for rough handling and damage. If
the box is damaged it should be kept until the contents of the shipment have been checked
mechanically and electrically. If the instrument is faulty, please contact your local distributor. Keep
the shipping material for the carrier’s inspection and insurance claim.
Keep the carton for future shipment
The Titan comes in its own shipping carton, which is specially designed for the Titan. Please keep
this carton. It will be needed if the instrument has to be returned for service.
If service is required please contact your local distributor.

Reporting Damage
Inspect before connection
Prior to connecting the product to the mains it should re-inspected for damage. The entire cabinet
and accessories should be checked visually for scratches and missing parts.
Report immediately any faults
Any missing part or malfunction should be reported immediately to the supplier of the instrument
together with the invoice, serial number, and a detailed report of the problem. In the back of this
manual you will find a "Return Report" where you can describe the problem.
Please use the "Return Report"
Completion of the Return Report is advisable so that the service engineer can easily understand
the problem being reported and correct/repair to your satisfaction. Without this relevant
information, it may be difficult to determine where the fault/problem lies.
1.7
Concerning Maintenance and Repair
Interacoustics is only considered to be responsible for the validity of the CE marking, effects on
safety, reliability and performance of the equipment if:
•
assembly operations, extensions, readjustments, modifications or repairs are carried out by
authorized persons,
•
a 1 year service interval is maintained
•
the electrical installation of the relevant room complies with the appropriate requirements, and
•
the equipment is used by authorized personnel in accordance with the documentation supplied
by Interacoustics.
It is important that the customer (agent) fills out the RETURN REPORT every time a problem
arises and sends it to Interacoustics, Drejervaenget 8, DK-5610 Assens, Denmark. This should
also be done every time an instrument is returned to Interacoustics. (This of course also applies in

Mounting a Cradle on the wall
In order to mount the cradle to the wall you will need the following tools: a drill and a screwdriver.
You may need to find out which plugs and screws are best to use depending on the material of the
wall.
Use the retaining plate of the cradle and a pencil to draw the
exact position of the 3 screw holes on the wall. Make sure that
the height is chosen in a way that you can still read the Titan
display when it is placed in its cradle.
Drill the holes and insert the plugs provided. Use three screws
to mount the retaining plate to the wall.
Put the power cable, printer cable and USB cable behind the
retaining plate. Attach these to the cradle before sliding the
cradle onto the retaining plate.

2.2.1.4
Calibration Cavities and Issues
The Titan cradle has a built-in 2cc cavity which can be used for a
quick validity check of the probe calibration. You can use the 0.2 ml,
0.5 ml, 2.0 ml and 5.0 ml cylinder cavities for more thorough checks.
To perform a calibration check, select a protocol that measures a
tympanogram.
Do not use an ear tip! Place the probe tip completely into the cavity.
Perform the measurement. Check the volume that was measured.
The allowed tolerance in the volume measurement is ± 0.1 ml for
cavities up to 2 ml and ± 5% for larger cavities. These tolerances are
applicable for all probe tone frequencies.
We strongly recommended calibrating each probe and contra phone
at least once a year. If a probe is handled roughly (e.g. dropped onto
a hard surface) it might need to be calibrated again. Calibration values
of the probe are stored in the probe itself. Therefore probes can be
exchanged at all times. The contra phone is, however, calibrated
together with the shoulder box. You should not exchange contra
phones from one shoulder box to another without calibrating.
2.2.1.5
Installing the Thermal Printer
To charge the printer battery, attach either the printer power adapter to the back of the printer (1), or use the
cable which connects the printer to the cradle (2). If Bluetooth is not available on your printer you should
charge by using the cable that attaches to the cradle (2).

The temperature of the battery pack in the
thermal printer will increase if it is powered
through both the printer’s power supply and
through the RJ12 cable to the cradle. Use either one power connection
or the other, but never both, as this may severely reduce the lifetime of
the battery.

When the Titan is used as a hand held unit it can use Bluetooth to directly print to either a thermal printer or
to most Bluetooth PC printers. However, functionality with Bluetooth printers is only guaranteed for the HP
Officejet H470 and HP Deskjet 6940 with use of the HP Bt500 Bluetooth dongle.
In order to use Bluetooth for printing, the Titan print option needs to be setup for connecting to a printer (and
not to a PC). Find this setting by switching on Titan and pressing Protocol | My Titan | Titan… Item
Bluetooth Connection should be set to “printer”. Change the option by pressing the R or L key on the
handheld unit.

The Titan battery automatically starts charging when placed in the cradle if this is connected to mains power.
Keeping the spare battery in the cradle charging compartment means you will always have fully charged
spare battery.
Interacoustics provides a medically approved mains power supply (ASA30M-0301) to be used for charging
the Titan. A DC USB adaptor can be used to connect the Titan to the medically approved mains power
supply (ASA30M-0301) when the cradle is not in use. Then the battery in Titan is charged within the same
time frame as if it was placed in the cradle.
The Titan battery can also be charged via connection to a PC with a USB cable provided.
Testing can be performed while the Titan battery is charging.
The following table gives an estimate of the charging time (ct) in hours for the battery. Be aware that
negative numbers mean that the battery is discharging. Charge times for the spare battery in the cradle and
the battery in the Titan while placed in the cradle are the same.

2.2.1.11 Changing Probes and Extension Cords on the Titan
The Titan probe can be connected in four ways to the device:
1) directly to the Titan
2) using the short extension cord
3) using the long extension cord with the shoulder box (small – for OAE & IMP)
4) using the long extension cord with the PreAmp (large – for OAE/IMP & ABRIS)
Note that the length of the tubing influences the pump speed. When the probe is directly connected to the
Titan, pump speeds are about 60% higher than when it is connected via the long extension cable with either
the shoulder box or PreAmp. For the most accurate measurements it is recommended to use probe while
connected via the shoulder box or PreAmp.
To release the probe or the extension cable from the Titan,
press the button at the back of the Titan and pull the probe or
extension cord out while holding onto the base of the probe or
extension cable.
Do not pull directly on the cord of the extension cable as this
can damage the tubing connections! Do not pull directly on
the probe tip as this may cause it to break!
Connect the extension cord or probe to the Titan by lining up
the red triangles and pushing the probe or extension cable
into the connection plate.
The probe can be attached to the extension cable by lining it
up correctly and clicking the probe onto the end. .

When you receive the Titan product it already contains the license including the software modules you have
ordered. If you would like to add another module that is available in the Titan Suite, please contact your
dealer for a license.
2.2.3.7
PC controlled Measurements with use of Bluetooth connection
If you want to use a Bluetooth connection to carry out PC controlled measurements with the Titan, you have
to assure that Bluetooth is installed on your PC. If Windows asks for a passkey during the installation
process:
The default passkey is 1234.
For further information about setting up a Bluetooth connection, please refer to the Bluetooth Installation
Quick Guides for Windows XP and Windows 7 at the end of the manual.
2.2.4

The shoulder box (used with IMP440/DPOAE440) contains calibration data for only one contra phone. The
specific contra phone is calibrated with the shoulder box and cannot be swapped over to another transducer
without changing the calibration data in the shoulder box.
Titan
Setup and Installation Manual
Page 26
The PreAmp detects which ID transducer is connected to it and will automatically read the calibration data
from the ID transducer. The PreAmp allows you to change from one ID transducer to another at any time as
they use the special Omnetics plug.
Note: If you want to run contralateral reflex measurements via the PreAmp, you will need a contra phone ID
transducer using the Omnetics plug. The contra phone that connects to the (IMP/OAE) shoulder box uses a
different plug and is not compatible with the PreAmp. Please contact your dealer if you require a PreAmp
compatible contralateral headset (ID transducer).
2.2.5
Handling and selection of ear tips
When using the Titan probe and CIR55 contra phone, appropriate ear tips must be used.
Always use a new ear tip for each patient to avoid cross contamination. The ear tip
is not designed for reuse.
The probe (and CIR55 contra phone) must be fitted with an ear tip of a suitable type and size before testing.
Your choice will depend on the size and shape of the ear canal and ear. Your choice may also depend on
personal preference and the way you perform your test.

When performing a quick impedance screening test you may choose an umbrella shaped ear tip. Umbrella
ear tips seal the ear canal without the probe tip going into the ear canal. Press the ear tip firmly against the
ear canal in such a way that a seal remains during the complete test.
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!
2.2.6
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.
1
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.
2
The button (2) on the PreAmp can be used to START or
STOP a test.

2.3
Cleaning the Probe Tip
In order to secure correct impedance measurements it is important to make sure that the probe system is
kept clean at all times. Therefore please follow the below illustrated instructions on how to remove e.g.
cerumen from the small acoustic and air pressure channels of probe tip.
Never clean the probe tip while the tip is still fitted on the
probe.
Unscrew the probe cap of the probe by turning in the counter
clockwise direction.
Remove the probe tip from the probe.
Take the cleaning tool apart to find the thin brush and thin
rigid plastic cord.
Use the plastic cord or brush to remove any debris from the
probe tip. Always insert the cleaning tool from the rear to
avoid accumulation of debris inside the small round vents.
Place the probe tip back onto the probe. Make sure that the
holes fit into the corresponding cavities.
Screw the probe cap back onto the probe. Finger force will
tighten the screw sufficiently. Never use tools to affix the
probe cap!
If any blockage or damage occurs to the sealing gasket, the
probe system can only be serviced by Interacoustics.

Interacoustics Standard
Uniform from 500 Hz to 1600 Hz, ±10 dB re. 1000 Hz
− Spectral properties: level
High Pass noise (HP):
Interacoustics Standard
Uniform from 1600 Hz to 4000 Hz, ±10 dB re. 1000 Hz
− Spectral properties: level
General about levels:
The actual sound pressure level at the eardrum will
depend on the volume of the ear. See Table 2 for
details.
The risk of artifacts at higher stimulus levels in reflex measurements are minor and will not activate the
reflex detection system Titan
