Firmware is the program that controls and runs your PM3.
We recommend running the most current firmware available for your PM3.
For PM3s on indoor rowers, there are two current versions of PM3 Firmware:
- Version 315 (released November 2012)
- Version 108 (released November 2012)
Versions 108 and lower are for monitors with the original microprocessor. The microprocessor used in the original PM3s was discontinued by the manufacturer. In order to use a different microprocessor, Concept2 needed to redesign the PM3. The redesign did not alter functionality between PM3s using different microprocessors but did require a new firmware version.
The first PM3s to use the new microprocessor were put into circulation in September of 2008. These PM3s were released with PM3 Firmware Version 303. If your PM3 Firmware Version is 303 or higher, then PM3 Firmware Version 315 is the current version for your monitor. The firmware versions are not interchangeable. That is, Firmware Version 303–315 will not work on a PM3 with Firmware Version 108 and lower, and vice versa.
For PM3s on SkiErgs, the current PM3 Firmware Version is Version 708 (released November 2012).
