There'll probably be lots of replies, but:
| 1209 | 1336 | 1477 | 1633 | where the integers are the
------------------------------------- frequencies in Hertz.
697 | "1" | "2" | "3" | "A" | Normally one of the two
------------------------------------- (the high tone? from my
770 | "4" | "5" | "6" | "B" | poor memory) is a bit
------------------------------------- "hotter" than the other,
852 | "7" | "8" | "9" | "C" | by perhaps a dB. I'm
------------------------------------- sure someone will set us
941 | "*" | "0" | "#" | "D" | straight on this if it's
------------------------------------- wrong ;-)
