Chapter 13: Reloading WA OAE Firmware (WA OAE Load
software)

The Welch Allyn OAE Hearing Screener runs on firmware that resides on a memory chip inside
the unit. Each Welch Allyn OAE Hearing Screener comes with this firmware pre-installed so that
the device is fully functional upon delivery. Users can, however, reprogram this memory chip with
a PC-based application called WA OAE Load. This application comes with every new system. You
can use this application if the delivered firmware becomes corrupted and must be reinstalled, to
update the date and time on the Welch Allyn OAE Hearing Screener, or to upgrade the system if
you receive new firmware.

To install the WA OAE Load application on your computer:

1. Turn on your computer.

2. Make sure the system date and time settings on your computer are correct. During the

WA OAE Load process, the date and time set on the PC will be used to set the clock
inside of the screener.

3. Locate the Welch Allyn OAE Hearing Screener Inservice Guide CD provided with your

Welch Allyn OAE Hearing Screener.

4. Insert the CD into the computer’s CD drive. If your PC supports automatic opening of the

installation program, you will see the following screen when the CD is opened.
