Step1.CounttheLongFlashes
Athree-secondinterval,duringwhichthePWR/RDYLEDisyellow,
separateseachrepetitionofthesequence.Thesequencebeginswitha
seriesoflongone-secondflashes—thatis,onesecondred,onesecond
yellow.Theselongflashesrepresentthedigitinthetenscolumn.There
canbeonetoninelongflashes,whichrepresentdigits1through9.For
example,onelongflashrepresentsthedigit1inthetenscolumn,and
ninelongflashesrepresentthedigit9inthetenscolumn.
