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:
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:
Creating new Protocols/Changing a Test Protocol Permanently
Changing a Test Protocol Temporarily
To make changes to the setup temporarily:
Importing and Exporting Test Protocols
The AC440 also allows you to import and export test protocols to other AC440 users.
Exporting a Test Protocol:
Importing a Test Protocol:
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

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

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

Designing a New Customized Test Protocol
Display combined screen allows for comparing different curves by default in the same graph. The option is also available from the front screen. Which curves to compare can be setup individually (see section Error! Reference source not found.).
Coupler allows you to select the preferred coupler to be used in the test protocol. Select from 0.6 cc, 1.2 cc, 2 cc, and Ear simulator (IEC 711).
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 the ANSI or IEC standard. In this case the dropdown list can be used to select an ANSI or IEC standard before clicking New. When asked if the new protocol should be based on a copy of the currently selected protocol, click yes.
