Vic,

Generally:
'1' Enter Program Mode
'3' Enter Utility Mode
'4' Enter Manual Mode
'7' Enter Learn Mode
'A' Enter Repeate Mode

But the whole list with description is a little long to key in, you
should contact Mobile Ed and get the "Users Manual" it describes all
the keys and the builtin functions that are tied to them (ie '3' '6'
is the Date Set function, and '3' '8' is date display...)

good luck,
