I did the way it is posted here about 10 times and got frustrated.
I could get all the way to the point of getting the word "SPECIAL" to come onto the screen.
What finally worked was to use the first part of the directions posted above to shut it off.
Then I used the manual for the actual procedure from that point on.
That worked the first time I tried it.
Don't ask me why.
I can't tell you what was the difference between the posted directions and the manual on the last part in the manual.
It worked,so it was not worth wasting the time trying to figure out the difference.
