prompted to enter the length of
sequence L. As suggested in the instructions, press
CIJ
(zero) to select the practice
mode.
As indicated by the display, you may press any of the number keys (1 - 9) to hear the
corresponding tone. The larger the number is, the higher the tone will be. The 1 (one)
key will give the lowest tone and the 9 (nine) key will give the highest tone. Confirm
this by pressing the number keys in sequence
(l,
2, ... 9). The game will require you
to memorize the tone associated with the keys. You should therefore practice with the
keys until you feel comfortable with the association. For beginning levels of play it is
only necessary to remember the two lowest tones
CD
and
m
keys.
