NOTICE One of the firmware updates in this document involves connecting and updating the front panel of the CS800. While it is not an overly complicated process, caution is required since the main radio update will not work without the front panel update, and missteps during the front panel update can render it inoperable.

Preface: The CS800 has two MCUs, one in the main radio body and the other in the front panel, and for this version of firmware both will need to be updated. Since the front panel makes use of a Prolific USB to Serial connection and driver, it is important to verify that this connection can be made prior to updating the radio.
