It is so exciting to see someone new just starting with the Optacon.
You will be able to read things that you can't with a scanner, because
with a scanner the characters have to be pretty close to what it
considers normal, whereas with the Optacon, you can use your own
judgment in interpreting the characters. Best of luck, and
congratulations!

right. So the threshold arrow is more on the 9 to 7 o'clock position of the
clock, or there abouts, according to what you need for letter thickness,
where the upper one will be from around 12:30 all the way to maybe 4, as
far
as it goes, the way I like it.

Subject: [optacon-l] Re: Training TipHi, Sarah,
Thank you all for your tips and suggestions so far.
I will get started with implementing them. But for now I have one
question
to help me get the settings right. Someone mentioned that the bottom knob
is
intensity (and therefore top is threshhold), and someone else said the
bottom knob is threshhold, so I am wondering which is which?
Thanks again for all the help, and please keep the suggestions coming if
you
have any. :)

Subject: [optacon-l] Training TipHi, Sarah,
This may seem strange but you should begin your practice with material
where you aelready know exactly what is on the page. For instance, print
out a page conweettaing three lines of dashes spaced several lines
apart.
Then practice with the page until you can:
1. locate all three lines of dashes:
2. follow each line across left to right and back again. Thesee tracking
skills will be a ong the most important you will have to master.
Using uch a page, you can also practice finding which is the blank side,
and the use of the thrdhhold knob and zoom lens to get the best
adjustments. so that you can read the lines of dashes clearly.
You can also make pages that contain a few different letteers spaced
widely apart cuch as c and o. The Optacon training material does contain
such pages but sometimes at the beginning you are best oof working with
things you designed yourself.
You'll be surprised at the number of variations possible in forming the
different letters and numbers. If you have address labels, try reading
your own address or even just your name. Eventually adjusting the
threshhold and the zoom lens will become second nature. The intensity
button can usually stay at one settting, however you find you like it.
Be sure to work for only short perionds at the beginning. Try hard not
to
move the finger thatt is resting on the array. The tracking hand with
the
camera is what moves.
Feel free to write to any of us off-list or to the list itself with any
questions. We will all be very interested to follow your progress.
Best of luck,
Catherine
