JamMan Enhancement ROM Power Up
The power up sequence is slightly different for the JamMan version and the ReJam versions of the Enhancement ROMs.

JamMan

On power up, the new ROM displays the letters "S", "t", "E", "C", followed by the version number.

ReJam

On power up, the ReJam turns on all front panel LEDS for several seconds. This is actually a diagnostic that allows you to check for bad LED segments.
