IMPORTANT
Please note that some transducers will only work
with a Fitting unit that run with firmware version
equal: 3.2.0.0.0247 or higher and Primus version 4.0

Check firmware procedure:
1. Please start the Audiometer software with the
Fitting Unit connected to the PC
2. Go to the menu: “Tool” at the top
3. Select: “Update Firmware” in the menu
4. Under Audiometer hardware check that
Current firmware version is equal or higher
than: 3.2.0.0.0247
Installation procedure:
5. If this is not the case, please install the
newest Audiometer software Primus version 4.0 that will prompt
you to install the latest firmware

NOTE
1. If you get the following dialog in Audiometer
software the: “Sound Booth Cable
Connection”. This means you are running
with an older firmware version that the
transducer does not support, therefore
update the firmware using the latest
Audiometer software as above.
