What's on the display of the TI (Snow)?

[nutrinoland]

hi guys...sorry about bringing up this old post,but i have the same question and i found this post through the search section....
I found info on the forum about the 5 bar meter, then the numbers 01 - 04 are the part numbers.....but i can find info on what the other 2 icons are on the display of the TI snow are..the - 2 rectangles and then - the arrow pointing to the semi circle icon..
i thought maybe RAM or ROM.....cant figure it out....anybody figured it out ??

thanks...
