Since the launch of the Finalizer Express no new software has been released. The current software is version 1.01. You can check this by holding down the most right hand key when powering up the unit on the front.
Scroll with the adjust up and down arrows until you see an "S" on the LED screen. Then press the softclip ON button, and you will see the current software version rolling over the screen.
If your unit should need an upgrade, it can only be done through the PCMCIA slot on the front with a PCMCIA card. In that case, please contact your dealer, to get a PCMCIA card with the software or get in touch with the TC Support Team.
