Firmware Update Instructions

1. Open the Prism Pro App on your mobile device

2. Log in with your Mira account

3. You will be prompted with the Firmware update if your organization has been granted access to the firmware update and the headset does not have the latest Firmware installed.

5. Select Download to get the latest Firmware Package. Alternatively you can select remind me later, which means that you or anyone else with the device will be prompted with the update screen upon login. 

6. The Firmware update will take a couple of minutes to download depending on your wifi speed. 

7. If the download succeeds you will see the following message. Select Continue.

8. Read the following instructions before proceeding with the installation. Then select Install

• Do not disconnect the mobile device from the headset
• Do not close the application 
• Keep the device in a stable position so that it does not move during the installation process. 

9. The installation will take about 35 minutes. During the installation process the headset will automatically restart and your phone may vibrate. 

10. Your phone may prompt a request to trust the external device upon restart. Please select Trust to proceed with the installation. Selecting Don't Trust or leaving this notification for longer than a few minutes can cause the installation to fail and have to be re-started.

10. When the installation has succeeded you will be presented with a success message. Select Continue to start using your headset. 

Troubleshooting

If any issues occur during the Firmware update, you will be presented with troubleshooting instructions. 

• Headset Disconnected - If your headset disconnects before the installation begins, you can reconnect the headset to dismiss the following message and proceed with the Firmware update.
• Your phone may prompt a request to "trust the external device" upon re-boot during installation. If not selected for a period of time, this can cause the installation to have to be re-started. If you run into this issue, simply go ahead and re-install (as per step 8), and check to see if the trust notification appears again (if it does, go ahead and select "trust").
