Hi,
Its not quite clear what you have been doing. Have you done a firmware update to Version 2.21?
If yes read this:
New firmware 2.21 available for the Mk.2/2N
then you'll know why it flashes red that there are new CF's (RTFM)
But first things first, we need to get you out of the Sim Mode!
-------
Press the right button then choose "Quit Sim" by moving the arrow down the menu with the left button. Press the right button. The dive is ended by immediatly returning to surface. After a few seconds the 2N returns to surface mode.
If you haven't done a FW update you may have fiddelded with the CF's. If you can't remember which ones you've changed you need to reset them all to default setting.
Once your back to the surface mode press the left button, from the Menu choose
> Reset Menu
> Reset CF, Gas & Deco
> Confirm Reset move cursor down to OK with left button then press right button to reset
Now the 2N is reset to the standard CF's
NOTE: If you've had some desat and/or Nofly from an real dive, this information will have been reset too. So you should not dive for at least 24 hours.
