Intended Use
The AD629 diagnostic audiometer is designed to be a device for diagnosing hearing loss. Output and
specificity of this type of device are based on the test characteristics defined by the user, and may
vary depending on environmental and operating conditions. The diagnosing of hearing loss using this
kind of diagnostic audiometer depends on the interaction with the patient. However, for patients not
responding well possibilities of various tests allow the tester to have at least some evaluative result.
result should not allow for ignoring other contra indications in this case. A full
audiologic evaluation should be administered if concerns about hearing sensitivity persist.
The AD629 audiometer is intended to be used by and audiologist, hearing healthcare professional or
trained technician in an extremely quiet environment. . This instrument is intended for all patient
groups regarding sex, age and health. Careful handling of the instrument whenever in contact with a
patient should be of high priority. Calm and stable positioning while testing is preferred for optimal
accuracy.
Precautions
1. No modification of this equipment is allowed without Interacoustics authorization.
Interacoustics will make available on request circuit diagrams, component part lists,
descriptions, calibration instructions, or other information that will assist service personnel to
repair those parts of this audiometer that are designated by the Interacoustics as repairable
by service personnel
1. Never insert or in any way use the insert headset without a new clean non defect test tip.
Always make sure that foam or ear-tip is mounted correctly. Ear tips and foam are single
use.
2. It is recommended that parts which are in direct contact with the patient (e.g. earphone
cushions) are subjected to standard disinfecting procedure between patients. This includes
physically cleaning and use of a recognized disinfectant. Individual manufacturer's instruction
should be followed for use of this disinfecting agent to provide an appropriated level of
cleanliness.
3. It is recommended that the disposable foam ear tips supplied with the optional EarTone5A
insert transducers are replaced after each patient tested. Disposable plugs also insure that
sanitary conditions exist for each of your patients, and that periodic cleaning of a headband or
cushion is no longer required.

 The black tubing protruding the foam ear tip is attached to the sound tube nipple of the
insert transducer.
 Roll the foam tip into the smallest possible diameter.
 Insert into the ear canal of the patient.
 Hold the foam tip until expanded and a seal is achieved.
 After testing the patient the foam tip including the black tubing is detached from the sound
tube nipple.
 The insert transducer should be examined prior to attaching a new foam tip.
4. If this apparatus is connected to one or more other devices with medical CE marking, to make
up a system or pack, the CE marking is only valid also for the combination if the supplier has
issued a declaration stating that the requirements in the Medical Device Directive article 12
are fulfilled for the combination.
5. When the instrument is conneted to a PC be aware of not touching the PC and patient
simultaneously
1. Be sure to use only stimulation intensities, which will be acceptable for the patient.
2. The transducers (headphones, bone conductor, etc.) supplied with the instrument are
calibrated to this instrument - exchange of transducers requires a new calibration.
3. Airborne sound radiation of the bone vibrator may effect the measurement if no masking is
used. Therefore, masking is mandatory when using bone vibrator.
4. 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 it must be observed that no mutual disturbance
appears.
5. Within the European Union it is illegal to dispose electric and electronic waste as unsorted
municipal waste. Electric and electronic waste may contain hazardous
substances and therefore has to be collected separately. Such products will be
marked with the crossed-out wheeled bin shown below. The cooperation of the
user is important in order to ensure a high level of reuse and recycling of
electric and electronic waste. Failing to recycle such waste products in an
appropriate way may endanger the environment and consequently the health of
human beings.
6. To prevent system faults take appropriate precautions to avoid PC viruses and similar.

Annual Calibration:
The AD629 had been designed to provide many years of reliable service, but annual calibration is
recommended due to possible impact on transducers.
We also required calibrating the AD629; if something drastic happens to a part of it (e.g. headset or
bone conductor is dropped on a hard surface).
