On February 16, 2005 Kenwood released a free Firmware Update for the TS480HX/SAT.
The detailed steps are fully described at:
http://www.kenwood.com/i/products/info/amateur/ts_480/firmware/ts480_updating_e.htm
Essentially, the process begins by first backing up your radio using Kenwood's free ARCP-480 Rig Control software. Then the Firmware update software is used to revise the rig.
The steps go as follows:
Everything is first disconnected from the RF deck.
The top cover of the rig is then opened to gain access to a switch inside the unit which must be gently moved from the "Normal" position to the "Update" position.
Power and Serial Cables reconnected.
Software self-extracted and Firmware updated.
Cables removed.
Internal Switch Reset to "Normal" Position.
Cover Replaced.
Cables and Control Panel reconnected.
Perform Full Reset to Rig.
The following is from Kenwood's website. You will find the direct URL's at the bottom.
