Yes I think so.
Boot the B2 back up.
Get the presets as you want them,
Halt the B2 from playing or doing anything..
Go to the from panel and if the time clock is showing (it is not showing it is compressing or anything),
press and hold in the Stop/Play button until "Saving" appears on the front display.
Wait for "Saving" to be replaced by the clock then power off the B2.
When you now power the B2 Up you should find that your Radio presets are as YOU left them.
