which keeps your specimen cool, and the halogen incident light above
adjusts for more clarity. The T-2400 has both upper and lower tungsten
lamps. With our value priced T-2400, T-2200 series and T-2600

MICROSCOPE PREPARATION

All these models are completely assembled. Remove the Vision
Scope from the packing and any protective coverings from the lenses.
Unpack the eyecups and slip them over the eyepieces.

Place head in support ring on base (excluding T-2400 model).
Carefully check the thumb screws to be sure that the head is firmly
attached to the base.

Check the coarse focus tension (T-2200 series & T-2600). The
knobs are oversized were designed for better gripping. The coarse focus
knob should turn easily to change the focus. Note that the arm will move
up and down when focusing. On the T-2400 coarse adjustment is the
single knob at the back of the pillar to raise or lower viewing head and
fine adjustment is made with the 2 knobs on either side of the viewing
head.

OPERATION

a. Place the specimen you are viewing in the center of the stage.

b. Accurately align the objective lens. Move the focus knob until the
specimen comes into view. Note that the viewing head will move up and
down when focusing.

c. The eyepiece tubes will spread apart or get closer together to fit
each individual. Place one hand on both eyepiece tubes and gently
move them in or out from each other until you see a single image with
both eyes.

d. Adjust the diopter to adjust the focus for individual viewing.

e. Turn off the power switch before connecting the power cord located
on the side of the microscope. The Vision Scopes are equipped with an
upper and lower illumination system. The upper light is a variable inten­sity halogen light and the lower light is a fluorescent light (Excluding
model T-2400). The switch for the light is a three position switch so that
the upper light can be on, or the lower light can be on, or both lights can
be illuminated (Excluding model T-2400).

f. Use the dimmer switch located on the side to adjust the transmitted
light (Excluding model T-2400).
