Introduction
This Quick Guide is intended to provide basic instructions on how to work with protocol setups in the AC440 module in the Affinity2.0 and CallistoTM suites.

Working with Individual Setups (Test Protocols)
There are many different demands and wishes regarding how an audiometer should both function and appear depending on the specific situation and national standards. One of the greatest advantages of the AC440 module is the flexibility, enabling you to tailor the system according to your specific preferences in the so-called “test protocols”. Below describes basic functionality on how to work with the AC440 Protocols.

Selecting a Test Protocol:

  1. Launch the Affinity 2.0 or Callisto™ Suite from Noah, OtoAccess™, or stand-alone.
  2. Ensure you are in the AC440 screen. Click on the AUD tab if Audiometry is not the default startup screen.
  3. Under Protocols and Sessions, both factory test protocols with standard/factory test parameters and personalized test protocols can be selected.

NOTE: The protocols available in the drop down will depend on whether factory defaults or country specifics defaults were chosen during the installation of the Affinity 2.0 or Callisto™Suite. Therefore, certain test protocols may be hidden. To hide or un-hide protocols, go to Menu | Setup | Show/Hide Protocols.

The AC440 Main Setup:

Once in the AC440 Setup, available tests will be listed to the left. Each test can be unfolded to access its options. Each test contains the following options:


Startup: These are the settings in which the test will start up.
Common: Allows for setting up more general settings of the specific test.
Keyboard: Allows for setting up macros for the dedicated Affinity 2.0 /Equinox 2.0 audiometry keyboard (if this is used).
Add-ons: Allows for setting up add-on features/subtests if available for a test. These require a special license.

NOTE: Some setup screens contain more than one tab offering multiple user controls.

In each setup screen, the following three buttons are found in the lower right corner:

  • Clicking OK will close the AC440 setup and save all changes.
  • Clicking Cancel will close the AC440 setup without saving any changes made.
  • Clicking Apply will save changes but without closing the AC440 Setup. The change will, however, immediately be active and visible on the screen behind the setup dialog.

Creating new Protocols/Changing a Test Protocol Permanently

  1. Click Menu | Setup | AC440 setup to enter the Main setup.
  2. Click New to create a new test protocol.
  3. A pop up window will appear, asking which settings to copy. Choose the protocol to be copied from the drop down menu and re-name the new protocol. Click Apply.
  4. The new protocol name will now appear in the list of protocols and it will now be possible to modify the settings. Browse the options and amend as desired.

    NOTE: For detailed setup options regarding each individual test available in the AC440, please refer to the Affinity 2.0 and Callisto™ Additional Information documents.

  5. When finished click OK (or Apply) to save the changes.

Changing a Test Protocol Temporarily
To make changes to the setup temporarily:

  1. From the drop down menu, ensure that the desired protocol to be changed is the chosen one.
  2. Enter the Temporary Setup by clicking the button in the front screen (or alternatively select Menu/Setup/Temporary setup).
  3. The Temporary Setup is identical to the Main setup. Browse the setup options to make temporary changes as if creating a test protocol and click OK.


    After the temporary changes have been applied, there will be an asterisk (*) beside the protocol name.

Importing and Exporting Test Protocols
The AC440 also allows you to import and export test protocols to other AC440 users.
Exporting a Test Protocol:

  1. Go to the AC440 Setup (Menu | Setup | AC440 setup).
  2. Click on Export.
  3. Select if the file is to be saved as “read only”. In this case the protocol file is locked and the clinician receiving it will not be able to make changes to it.
  4. Browse for the location on the PC or USB where the test protocol is to be saved.
  5. Click Save. Other AC440 users will now be able to upload the test protocol using the Import function.

Importing a Test Protocol:

  1. Go to the AC440 Setup (Menu | Setup | AC440 setup).
  2. Click Import and browse to the location on the PC or USB where the test protocol file has been saved.
  3. Click Open.
  4. The test protocol will then appear under Name.
  5. After saving it by clicking OK the test protocol can be selected in the List of defined protocols in the front screen.

Note: If the protocols were exported as “Read Only”, imported protocols will not be able to be imported edited.

This Quick Guide is intended to give a brief introduction on how to work with, create or edit protocols in the Affinity 2.0 and Callisto™ software suites.

Introduction
The Affinity 2.0 and Callisto™ software suites all have pre-defined protocols. Most of these protocols can easily be copied, modified or created from new. These modifications can be either permanent or temporary.

Working with Protocols
Selecting a standard test protocol:

  1. Open the Affinity 2.0 Suite from your patient management system, Noah, OtoAccess™, or stand-alone.
  2. Click on the REM tab
  3. In the List of Protocols, all customized and standard test protocols are listed.

Designing a New Customised Test Protocol

  1. Enter the REM440 setup by pressing Menu/Setup/REM440 setup.
  2. Press New. A pop-up will ask whether the new test protocol should be based on a copy of the currently selected test protocol. When asked by the message box:
    YES: The system will create a copy of the current test and allow you to add new tests, make changes, and save it under a new name.
    NO: The Selected tests section will be blank and you can create a new test from scratch.
  3. Name the test protocol setup in the Selected protocol section.
  4. Select the tests to be included in the test protocol. Mark a test by clicking on it and press the Add. Double clicking on a test will also select it. Choose all the tests for the test protocol using this procedure.
  5. To remove a test selected by mistake, select it under Selected tests and press Remove. The test will then jump back to the Test selection list.
  6. If the order of the tests is to be changed, use the two Move arrow buttons.
    Mark the test to be moved and press one of the arrow buttons. Depending on the direction of the selected arrow, the test will then jump up or down.
  7. To make adjustments to the parameters of each selected test press Settings. This will open a new window similar to below.

    In this window you can manipulate your individual parameters which relate to the test within your test battery including renaming, input level, stimulus type, curve smoothing index etc. Once you have set and are happy with this, please click Apply to save and keep the screen open or OK to save and Exit. Pressing Cancel will exit the window and discard your amendments.
  8. You may also notice that in the bottom left corner of the Test settings window that there are additional settings (see below). These settings can help you to define how you want your software to be displayed and how curves are grouped via the Combined Screen section. You can also default your REM protocol to select the most recent Audiogram here. Finally, your prescription settings can be defaulted in this section by clicking on Fitting Prescription.

    Note: Prior to creating a new test protocol you may wish to select a protocol type in the Protocols to view dropdown list. This function is practical if you for example wish to create a new protocol based on elements from a pre-existing protocol prior to creation. When asked if the new protocol should be based on a copy of the currently selected protocol, click yes. See step 2. above.

Importing and Exporting Test Protocols
The REM440 also allows you to import and export test protocols to other REM440 users.

Exporting a Test Protocol:

  1. Go to the REM440 Setup (Menu | Setup | REM440 setup).
  2. Click on Export.
  3. Select if the file is to be saved as “read only”. In this case the protocol file is locked and the clinician receiving it will not be able to make changes to it.
  4. Browse for the location on the PC or USB where the test protocol is to be saved

    Click Save. Other REM440 users will now be able to upload the test protocol using the Import function.

Importing a Test Protocol:

  1. Go to the REM440 Setup (Menu | Setup | REM440 setup).

What is the Rate Study Protocol?
The preprogrammed Rate Study test is designed to evaluate the integrity of the auditory nerve and look for retrocochlear lesion abnormalities.. Changes in response latency between fast stimulation rates and slow stimulation rates are recorded and compared. The Eclipse offers both slow and fast markers and performs the calculation between the inter-peak Wave V latencies (between Left and Right) as well as the intra-peak latency shift change from slow to fast rate.

How does it Work?
The test is run like a traditional ABR. The clinician tests at a high intensity (i.e.. 90dBHL) with a slow rate (i.e. 7.7Hz). A second run is completed using a fast rate (i.e. 57.7Hz). The Wave V for all four tracings is marked with the appropriate markers. After they are marked, the interaural wave V and the intra-aural shift from the rate change is calculated.

An interaural wave V latency difference greater than 0.2 to 0.4ms is generally considered abnormal (Bauch et al., 1996; Selters & Branckmann,1977)
