Application
The Cordless Comprehensive Dual Purpose Scope combines the
features of a standard compound microscope with some limited features
of a stereo microscope. It is available with a monocular head (T-1931C),
a dual opposing head (T-1932C), or a Seidentopf binocular head (T-
1933C). All models come with an x/y floating stage, a light rheostat for
light control, and a longer working distance to allow fairly thick specimens
to be viewed. Additionally, there is a separate top light for viewing large,
macro, or opaque specimens and a bottom light for standard microscope
slides, and a longer working distance.

Microscope Preparation
Open packing box carefully, and lift microscope out of shipping
container. Remove all packing materials on eyepieces, stage, and
illuminator.
Check the coarse focus tension. The knobs are oversized, designed
for better gripping. The coarse (larger) focus knob should turn easily to
change the focus. The stage should move up and down when either the
coarse or fine adjust knobs are turned. Watch the up-down motion of the
stage; it should not drift or slip on its own.
Check the stage stop feature. The stage stop is a knurled thumb
screw with a lock nut found on the main frame, just behind the stage. To
check the stage stop, place a prepared slide in normal position for
viewing. Place the 40x objective into viewing position and move the
coarse focus knob until the object and stage are as close together as they
can be WITHOUT TOUCHING. Look through the eyepiece at the slide,
and get the specimen into focus. The objective should be very close to
the slide, but not touching. If the stage stop is not set correctly, loosen the
locking nut and thumb screw, and reset the stage stop, tightening both
when correct position is attained.
Microscope Use and Instructions
Visit the Ken-A-Vision Web site, http://www.ken-a-vision.com/pdf/
MicroscopePrimer.pdf, for a Microscope Primer on general microscope
usage.
Operation
The NiMH batteries of your microscope need to be charged. Plug in
the round pin adapter from the supplied battery charger (or a Ken-A-
Vision Multicharger, SCGN06) into the back of your microscope. Connect
the opposite end to an electrical outlet. Charge the unit overnight
(approximately 12 hours or more) and your microscope is now ready for
up to 40 hours of continuous operation.
Power switch
This microscope has a double switch at rear right of the microscope.
Depressing the right side switch controls the bottom illuminator (sub-
stage transmitted light), providing light through the condenser for a
standard microscope slide. Depressing the left side switch turns on the
supra-stage incident light for macro and opaque objects. The center
position of the switch is OFF.

Focus
For microscope slides - place a specimen slide under the stage clips
and move into position for viewing. Use the 2x objective first. Raise the
stage until it will go no higher (stage stop controls this). Then looking
through the eyepieces and using the coarse adjust knob, lower the stage
until the specimen is in focus. Use the smaller fine adjust knob to now
sharpen the focus and attain maximum resolution. Now rotate the 4x
objective into place, and you should only have to use the fine adjust to
achieve a crisp focus (The microscope is Parfocal). Now the 10x and 40x
objectives can be similarly utilized if needed.
With coaxial focusing both the coarse focus (large knob) and fine
focus (small knob) are on the same axis. Having both sets of knobs on
the same axis makes it easier to switch from one focus knob to the other
without moving eyes away from the eyepieces.
Eyepiece(s) and Head
The widefield eyepiece is locked in to place to avoid loss. A pointer is
built in to the eyepiece.
There are three kinds of heads available for the T-193XC (Cordless
Comprehensive Dual Purpose Scope) series of microscopes. The T-
1931C is monocular with a single eyepiece.
The T-1932C has a dual opposing head which allows two people to
look at the same specimen at the same time, or connect a camera to one
eyepiece for projecting image to a group. There is a diopter on one
eyepiece tube for independent focusing of each eyepiece.
The T-1933C has two eyepieces with a diopter on one eyepiece to
compensate for differential visual acuity between an individual's eyes.
The Seidentopf binocular head allows adjustment for interpupillary
(interocular) adjustment. The eyepieces will move to exactly match the
distance between the user's eyes.

Care and Maintenance
Your microscope is a fine precision instrument and should be treated
with care. When not in use, it should be protected from dust by the plastic
cover provided. Lenses and eyepieces should be cleaned periodically
with optical lens tissue which is soft and lint free. Painted surfaces can be
cleaned with a moistened cloth.
