INTERRUPTED FIRMWARE UPDATE RECOVERY
If a firmware update is interrupted by loss of power to the CHAT 60, the USB cable being disconnected, or an
unexpected programming error, the CHAT 60 may not function properly. To restore firmware, boot the CHAT 60 in
Generic mode using the instructions shown below.
Disconnect the USB cable from the CHAT 60 1.
Hold down the 2. MUTE button while re-connecting the USB cable.
The 3. Update Firmware Recovery screen appears.
Click the 4. Update Firmware button and follow instructions that appear on-screen. During the update, the messages
“Initializing” and “Recovering” appear above the progress bar.
When the firmware file is recovered, the 5. Update Firmware utility automatically runs (see the Update Firmware
section for details).
The firmware is now restored and your CHAT 60 is ready to use.
In rare cases, Generic mode is unable to restore the firmware. If this occurs, the CHAT 60 automatically re-boots in
protected (DFU) mode and attempts to restore the firmware. Follow the on-screen instructions then click the Update
Firmware button, or contact ClearOne’s Technical Support for assistance.
