Step2.CounttheShortFlashes
Thelongflashesarefollowedbyshorterflashes;eachshortflashlasts
aboutone-fifthofasecond—thatis,one-fifthofasecondred,one-fifthof
asecondyellow.Theseshortflashesrepresentthedigitintheones
column.Again,therecanbeonetonineflashes,whichrepresentthe
digits1through9.Forexample,oneshortflashrepresentsthedigit1in
theonescolumn,andnineshortflashesrepresentthedigit9intheones
column.
Usingthismethod,thePWR/RDYLEDflashesthefollowingsequenceto
representerrormessage11:
<threesecondsyellow><onelongredflash><oneshortredflash>
<threesecondsyellow>...
