How to Avoid Undesirable Side Effects
During the development of the hearing aid analyzer, Audioscan performed a rigorous Risk Assessment to identify any undesirable side effects that a user could be exposed to during the use of the Axiom, and incorporated numerous risk reduction design elements into the Axiom to minimize the risk to users and patients.
Following are the actions which a user should take to ensure that these risk control measures continue to be effective
Loud Sounds:
The Axiom is designed to produce sound pressure levels as high as 85 dB at the probe reference microphone. Exposure to these levels for more than 7 hours can produce hearing damage. When such levels are amplified by a hearing aid, the level in the ear canal will be determined by the settings of the hearing aid but may reach levels that can produce hearing damage in less than 30 seconds. To avoid this possibility,
1. hearing aids should be adjusted to limit sound pressure levels to safe levels
2. the maximum TM SPL setting (see Max TM SPL Setup) should be used to terminate tests if an unsafe level is detected in the ear canal
3. test levels should be limited to 70 dB SPL except when necessary to verify the limiting levels of the hearing aid, in which case, the test should not last longer than 15 seconds
4. be aware of the test signal and patient reaction during a test and be prepared to respond to any sign of discomfort by reducing the SPL setting, switching off the equipment or the hearing aid, or removing the patient from the area.
When using the equipment to measure the Real-Ear to Coupler Difference in small ear canals, it is possible to induce a hearing loss if the test is allowed to continue for more than 1 hour. Since accurate results can be
10
Axiom®User's Guide Version 1.8  May 2015
obtained in less than 10 seconds, this possibility should never occur in normal practice.
Power and Grounding:
This product contains numerous safety features to ensure that the probability of electrical shock is as low as reasonably practicable. In order to ensure that all of the safety features work optimally you must ensure that the power cord is plugged into a grounded outlet. Any line-powered peripherals connected to the Axiom must comply with UL/IEC 60601-1 OR comply with UL or IEC or ISO safety standards for such equipment, AND a) be operated from an isolating transformer complying with UL/IEC 60601-1, OR b) be kept at least 6 feet (1.8m) from the patient.
Ear Infection:
Probe tubes or RECD foam tips should not be re-used on another patient. There is a possibility of transferring an ear infection to the other patient. Probe tubes and RECD foam tips are for single-patient use only. Do not attempt to clean or re-use.
Ear Canal Discomfort:
An otoscopic examination should always be performed prior to inserting a probe tube into the ear canal to ensure that it is healthy and free of obstructions. Care is needed when inserting probe tubes into the ear canal. Although the probe tubes are made of soft, flexible material specially designed for this application, it is possible to scrape the ear canal or touch the eardrum causing brief discomfort. You should carefully follow the instructions in “Positioning the probe tube” section of this User’s Guide.
11
Axiom®User's Guide Version 1.8  May 2015
2 Getting Started
This section provides instructions for unpacking the Axiom and connecting various components and associated items.
Unpacking and connecting
1. Carefully unpack the components of the Axiom from the shipping box and check the contents against the enclosed packing list.
2. Locate the Axiom on a solid surface in a quiet room and choose a location for the speaker and the client such that they will be about 2' (0.6 m) apart and both at least 4' (1.2 m) from any reflective surface. If the speaker is to be mounted on a desk, it should be at the edge facing outward. A room with sound-absorbing floor, ceiling and walls is recommended.
3. Turn the Axiom over and connect the on-ear probe microphones and the RECD transducer as shown.
4. Dress the leads out the sides, front or rear of the Axiom as appropriate for your work setup and turn the Axiom over, placing it on its rubber feet in the place where you will use it.
5. Open the lid of the test chamber by using your thumb to roll the rubber roller toward the front of the Axiom. This is made easier by placing your fingers under the front lip. When sealing the chamber in its closed position, place your fingers on top of the lid and use your thumb to roll the rubber roller toward the rear of the Axiom.
12
Axiom®User's Guide Version 1.8  May 2015
6. Plug the reference microphone and coupler microphone in to their respective connectors in the test chamber.
7. Connect the speaker to the speaker connector on the rear connector panel.
8. Connect a video monitor (HDMI or DVI with adapter) to the PRIMARY MONITOR connector on the rear
13
Axiom®User's Guide Version 1.8  May 2015
connector panel. This connector must be used if a single monitor is connected. An additional monitor may be connected to the second MONITOR connector.
9. When connecting both of the Axiom's monitor connectors to TV displays -- The set-up procedure should be as follows:
1. Connect both HDMI cables.
2. Power on TV's & assign proper input on both
3. Power on Axiom & Wait 45 sec for boot up until splash/welcome screen would appear
4. Power cycle TV if video isn’t displayed
5. If video does not appear on either TV, first try power cycling the TV, then try re-booting the Axiom.
Failure to follow operating instructions could place the user or operator at risk.
WARNING: To avoid the risk of electrical shock, monitors connected to the Axiom must comply with UL/IEC 60601-1 OR comply with UL or IEC and ISO safety standards for monitors AND a) be operated from an isolating transformer complying with UL/IEC 6061-1 OR b) be kept at least 6 feet (1.8 m) from the patient.
10. Connect a USB mouse (included) to one of the USB connectors on either side of the Axiom.
11. Connect the Axiom power supply (included) to the power connector on the rear connector panel.
12. Connect the power cord (included) from the Axiom power supply to a GROUNDED electrical outlet. In the USA and Canada, this outlet should be marked Hospital Grade.
WARNING: To avoid the risk of electrical shock, use only the power supply and power cord supplied with
the Axiom and connect it only to a grounded (protectively earthed) electrical outlet.
WARNING: To allow electrical power to be rapidly disconnected in the event of an emergency, position the
power supply in an accessible location so that the power cord may be quickly disconnected.
General care instructions
Probe tubes are for single patient use only. They may be wiped with alcohol wipes for re-use with the same
14
patient, but must not be used with multiple patients. Attempts at ultrasonic cleaning usually result in cerumen becoming lodged in the lateral end which causes irreparable damage to the probe microphones.
The case can normally be cleaned/dusted with a damp cloth, however if it is soiled we recommend wiping with a mild solution of water and detergent, or with alcohol-impregnated wipes deemed safe for use on electronic equipment. Parts that come into contact with patients (the probe module body, cable, and blue lanyard) should be regularly wiped down with alcohol wipes.
Hearing instruments should be cleaned prior to introduction to the test chamber due to the difficulty of sanitizing the acoustic foam. Custom hearing instruments must be cleaned with disinfectant towlettes (i.e. audiowipes) prior to placing in the test for this reason and to minimize contamination of the blue putty used with the HA-1 coupler. The acoustic foam in the floor of the test chamber is easily removed and should be replaced if badly worn or soiled.
Audioscan recommends periodic replacement of the blue putty used with the HA-1 coupler to ensure cleanliness. Both couplers and coupler mic can be wiped down with alcohol wipes as needed.
Ensure that all safety and usage recommendations on cleaning product packages are followed.
Microphone care
Coupler microphone:
Axiom®User's Guide Version 1.8  May 2015
1. DO NOT twist the cable when attaching a coupler to the coupler microphone. Turn only the coupler or unplug the coupler microphone before turning it.
2. DO NOT leave the coupler microphone plugged in when transporting.
3. DO make sure that the 2cc coupler is tightly screwed to the coupler microphone when performing hearing instrument tests. Coupler leakage can cause feedback and erratic response curves.
4. DO make sure the tubing on the BTE (HA-2) coupler is free from any cracks/tears.
5. DO make sure that any replacement tubing used on the BTE coupler is either obtained from Audioscan, or is #13 heavy wall earmold tubing exactly 10 mm in length.
Probe microphone:
Debris can alter the probe module reference microphone calibration and frequency response and can permanently clog the probe module port.
1. DO NOT reuse probe tubes. Probe tubes can be wiped with alcohol wipes for re-use with the same patient, but must not be used with multiple patients. Attempts at ultrasonic cleaning usually result in cerumen becoming lodged in the lateral end which causes irreparable damage to the probe microphones.
2. DO NOT attempt to open or repair the probe microphone. Attempting to repair the probe module may lead to damage or alteration of the factory calibration.
3. DO keep the probe module and probe tubes in a clean area.
4. DO stow the probe module when not in use or when transporting the Axiom.

3 General Operation
This section describes the use of a mouse or QWERTY keyboard to control the Axiom and to enter data, and the use of the (optional) barcode scanner to enter data from printouts produced by Audioscan analyzers. It also provides instructions for updating the Axiom operating software.
Switching ON/OFF
See Getting Started for instructions on connecting the Axiom to its external power supply module, the module to an electrical outlet and the location of the standby switch.
To start the Axiom, set the standby switch to its "ON" position. The green light on the right rear corner will light and the instrument will begin its start-up sequence which will take a few seconds.
To shut down the Axiom, switch the standby switch to its "OFF" position.
Note that the Axiom receives low voltage electrical power from the external power supply module. The standby switch on the rear of the Axiom disconnects this electrical supply but the power supply module is always on
as long as it is connected to a live electrical outlet. The green light on the power supply module indicates that it is receiving electrical power from the outlet.
Input device operation
The Axiom is operated by using a USB mouse (included) or a QWERTY keyboard (not included) to select icons and menu items, operate on-screen buttons and to enter audiometric data.
To activate an on-screen icon or button, or to select an item from a menu, use the mouse to place the screen pointer over the icon, button or menu item and left click. To enter a data point on a chart, such as an audiogram, place the screen pointer over the desired point on the chart and left click. To move the data point, place the screen pointer near the new location and left click. To delete a data point, place the screen pointer on the data point and left click. To summon a cursor on a graph, place the screen pointer on the graph and left click, then navigate to the point you want to identify; left click again to hide the cursor.

7 Printing and Storing Results
The Axiom can print results for future reference, as well as store results in computer files for future use. Using a web browser, you can capture the Axiom's screen image for printing or saving on any computer. The Axiom can also store audiometric data and test results in the optional Audioscan NOAH Module.
Printed output includes the graphical screen image that is showing when you select [Print]. Printed output can optionally include tabular results, text notes, and printed guidelines for handwritten notes. The Printing Setup controls which of these optional components are included in the output, as well as whether output is sent to a printer or saved in a file.
With the Axiom connected to a network, you can capture the Axiom screen image through your computer's web browser. You can then print or save the screen image using the computer's printer or file system.
The Axiom can store its input data and test results in session files. Restoring a session file restores the patient assessment data and test results as the Axiom was when the file was saved. The Session Setup controls where session files are stored. Session files can be stored locally on a local USB drive, or in a Windows-shared folder on a network.
Storing data in NOAH
The Axiom can store data using the optional Audioscan NOAH Module that runs in the NOAH framework on a Windows PC. Using the Module requires that both the Axiom and the Windows NOAH PC be connected to the same network.
The NOAH Module allows you to store the client assessment data, such as HL, UCL and BCT audiograms, and the WRECD, for use in future client visits. Since the assessment data are stored in the HIMSA NOAH public data format, then they can also be obtained from or exchanged with other NOAH modules that comply with the public standard. For example, the Axiom can restore audiograms from another manufacturer's audiometer.
The data are stored as actions in NOAH client records. The Axiom can later restore the assessment data from the Module as the starting point for follow-on measurements with the same client. The Module stores Axiom test results as screen images. The NOAH Module can display or print the stored screen images for comparison with the future test results.
Contact Audioscan or visit www.audioscan.com for details about the Audioscan NOAH Module.
! NOTE: If a printout or session file identifies the printed or saved data as belonging to an individual client, it becomes Individually Identifiable Health Information and must be protected under the HIPAA Security Rule. See Appendix 1: Manufacturer Disclosure Statement for Medical Device Security.
Printing results
The Axiom can print results on a printer or save results in a file for future printing and viewing. Printing Setup allows you to select the printer or file location, as well as to select the file output format. The Page Setup options allow you to select the content to be printed or saved. Results are printed as graphical images of the Axiom screen, and can optionally include the tabular view for tests that define it. Additional printed elements include informational headers and footers, as well as typed notes and guidelines. The following sections describe how to set up printers and files.
Printing setup
Use Printing Setup to control the output and page setup options for printed output. To enable printing, check [Enable]. To send the output to a printer, select Printer. To save the output to a file for printing or viewing later,
