Placement
of the CCTV unit on a standard table or desk is often too high for proper
reading with a CCTV and may cause neck and shoulder strain. To help
reduce the development of neck or shoulder strain, use of an adjustable
chair or table works best. Either of these items will allow you to sit
at the proper height which is when your eye level is a few inches
below the middle of the monitor screen.
Location
of the CCTV unit in the room is another important factor. The CCTV should
not be placed next to a window where the sun shining in can cause glare
on the monitor screen. The lights in the room should be evenly distributed
and not focused directly on the CCTV user or the monitor screen.
Read
for only about 15-20 minutes at a time when you are a new CCTV user
because your eyes will get tired quickly from this new method of reading.
Take
breaks often until you have adjusted to this new style of reading so
that your eyes have a chance to rest. Without rest, your vision can
seem worse than it actually is. For some, eye-strain can also develop.
Ease
of use comes with time and practice. Be patient! This is something new.

| General
Tips: |
1.
Sit in a comfortable position with your back supported.
a. The bottom portion of the screen should be just below eye level.
b. Do not tilt your head backward or forward in a way that can lead
to neck strain.
2.
If you have difficulty locating something in your reading or working
material, try this trick:
a. Locate the place on the page where you want to start reading. Put
your finger on the spot. Keeping your finger on the spot, place your
material under the CCTV. Then look at your finger on the monitor.
b. Ask someone to use a highlighter (green or purple) to outline the
area of a page that is important. This can be especially helpful when
using a map where you are locating information within a certain block
or neighborhood.

Writing
Tips:
|
1.
Make the writing surface stable.
a. When you first start writing, try locking down the table, and move
your hand across the page. When you run out of line, you will need to
move the paper or unlock and slide the tray.
b. When you are more comfortable with writing, you can choose to move
your material or the tray. One option is to move the tray slowly to
the left as you write so that your hand does not move.
2.
Use as little magnification as possible when writing. You may find that
if you enlarge the page you are writing on too much, your writing will
be too small to read.

Writing
Paper:
|
1.
Lined paper is easier to write on than blank paper. The lines provide
you with a reference point for your letters.
2.
Experiment to find the kind of lined paper that works best for you.
You may want to use bold line paper and a marker at first, then move
to regular lined paper and a pen as you become more comfortable with
writing.
|
Writing Implements:
|
1.
Many people prefer using a medium black Rolling Writer or
Uniball pen for writing under the CCTV. Writing is sharp
but not thick when these pens are used.
2.
Try using a pencil when you might need to erase. Many people are able
to see writing in pencil under a CCTV. But remember, the darker you
write, the more difficult it will be to erase.
|
| Holding
the Pen: |
1.
Focus your attention on the tip of your pen as you write. Keep your
hand out of the magnified image by gripping the pen further back.
2.
Try to hold the pen naturally. Make sure it is not blocking the light.

Other
Uses: |
1.
Use the CCTV to read directions on the back of food boxes, cans and
medicine bottles. When the object is a cylinder, you will need to slowly
turn the object to the left to read the print.
2.
Shiny objects sometimes reflect bright light into the camera. You may
want to slightly tilt a photo or shiny object toward you, or rest it
on the edge of a book, until the reflection goes away.
3.
Dont limit your use of the CCTV just to reading! Use it to view
a remote control, calculator or telephone keypad.
4.
You can also use your CCTV for needle threading, craft work, drawing
and painting, or painting fingernails!

Tips:
|
1.
Use the color mode:
a. If you have sensitivity to glare; the background is softer.
b. For looking at food labels.

d. To view photographs
e. When ordering items from catalogs.
2.
Use the Black-on-White mode for:
a. Reading text
b. Writing
c. Materials with colored backgrounds to heighten contrast
3.
Use the Black-on-White high contrast mode for:
a. Reading the newspaper
b. Reading anything with a dull background
c. Anything you need extra contrast
4.
Use the White-on- Black mode for:
a. To reduce glare or light
