Introduction 1.1
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. Thus, a “normal hearing” 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 an audiologist, hearing healthcare professional or trained technician in an extremely quiet environment. 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. It is recommended that the instrument be operated with an ambient temperature range of 15-35 degree Celsius (59-95 degrees Fahrenheit).
1.2
Precautions Indicates a hazardous situation which, if not avoided, could result in death or serious injury. Used with the safety alert symbol, indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. is used to address practices not related to personal injury
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. 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. 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.
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. 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.
4. 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. 5. To prevent system faults take appropriate precautions to avoid PC viruses and similar.
1.3

Care and Maintenance
The performance and reliability of the AD629 will be prolonged if the following recommendations for care and maintenance are adhered to: Great care when handling the headset: Great care should be considered when handling the headset as dropping it may alter the calibration. 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).

Patient Communication The operator may communicate with the patient using Talk Forward (when speaking to the patient) and Talk Back (when listening to the patient). Please find the connection overview in the previous section.
5.1
Talk Forward
Talk Forward is activated by the “Talk Forward” button (15). AD629 contains three microphone connectors which will work in the following priority (depending on which one(s) is connected):
Priority 1: The mini jack in the left side of the instrument – can be used with a headset together with the headphone connector. This has the first priority. Priority 2: The swan neck microphone (1) of the AD629 is located above the “Talk Forward” (21) button. If no mic. is connected to the priority 1 mic., this will be used. Priority 3: The pack panel contains a “Mic 2” mini jack connector that can also be used for talk forward, e.g. with an external table mic. If no mic. is connected to the priority 1 or 2 mic., this will be used.
The image below will be shown while the talk forward is active (by hold the button down) where the calibration (gain) level and intensity level for patient communication can be adjusted. To change the calibration level the clinician would adjust the HL db dial (41) to the appropriate level. To adjust the Intensity level the dial in channel 2 (43) would be used.
5.2
Talk Back
The operator may use Talk Back in one of the following ways:
AD629
If no headphone is connected to the Talk Back (left side connector), the voice is wired through the Talk Back speaker next to the display (2). If a headphone/headset is connected to the instrument, talk back with come through this instead.

Saving Sessions and Creating Clients
Test results can be saved by selecting “Save Session” (19). First a dialog with the list of clients presented:
In this case the client with id 2311667755 named Simon Hansen is selected. In this case there are only 3 clients in the AD629 memory – there may be 250+. Each client can have a number (in theory unlimited) of sessions (i.e. measurement test data) stored under it. Use the main dial (41) to scroll up and down in the list of clients. If you want to store the session under one of the existing clients, just press
. If you want to create a number of clients press.
The patient‟s details can be saved by pressing “Create” where the following screen will be seen:
The clinician will continue to save the patients details as follows:
AD629
The masking dial (43) is used for scrolling between Id, First Name and Family name. Use the Tone Switch / Enter button (42) to add one of the fields, e.g. Id. Use the two dials (41) (43) to move the cursor to select the appropriate letter or number. See dialogs below. Press the Tone Switch / Enter button (42) to activate each button.
