[CW] Island Keyer II help!

[George Ensign]

Hi Code Guys.
I have a Island Keyer II and somewhat confused about the memory
options.  I have read the manual, but putting something's into operation
escape me.  I am trying to use the keyer on a 10 mtr. beacon.  The basic
memory's 1 thru 6 are to short, so I would like to know the key strokes
to access the various banks and chapters.  I have played and played and
can't seem to get the proper sequence.  Also, when I try the embedded
command for a delay (?Dxxy) in the text, it plays in the message as d
plus the numerical delay time plus the letter I have inserted as "y", in
other words, it sends what I have keyed in as the embedded command.
Obviously, I am going about this in the wrong fashion.  Can any of you
guru's set me straight?
Thanks, 73's and have a great day, George N9HI
