INTERRUPTED FIRMWARE UPDATE RECOVERY
If firmware programming was interrupted (such as by a power loss or an accidental cable disconnection), the CHAT 170
might become unstable. The CHAT 170 software will boot into a generic mode and the Generic Mode screen will be
displayed.
The Generic Mode (DFU) recovery screen appears . To perform the firmware update, click the Update Firmware but-
ton (see the Update Firmware & Database section in Chapter 4: Using The CHAT Application for detailed instruc-
tions). The messages “Initializing” and “Recovering” appear above the progress bar, followed by the typical messages
that appear during a firmware update. The update then continues to completion.
If the CHAT 170 attempts to recover from a programming error by booting up in the Generic (DFU) mode, a series of
instruction windows will be displayed. Follow the on-screen instructions to resolve this issue.
