c. Avoid touching the glass surface of the bulb with bare hand. Any oil
brought onto the bulb by the bare hand will negatively affect the heat dissi-
pation and shorten the life of the bulb. Clean the bulb surface if the user has
touched the bulb surface accidentally.
e. Replacement bulbs may be purchased on Ken-A-Vision web site under

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. ainted surfaces can be cleaned with a
moistened cloth.
When using the optional 100xR objective oil emersion lens, be sure not to
leave any oil on the lens after use. Dip a cotton swab or lens paper with a
small amount of denatured alcohol, and clean the lens surface carefully. Do
not use aggressive solvents to clean lens.

An in-base illuminator is built into the bases of these microscopes. Bulb
replacement can be done from the underneath side. See Bulb Replacement
instructions. The built-in 20 watt bayonet incandescent bulb or 5 watt fluores-
cent provides all the light needed for illumination. Do Not Use Any Other Bulb
As It May Damage The Unit.

Be sure x-axis control knob lever is in "unlock" position and while looking
through eyepieces make sure x-axis control knob is in middle. Each micro-
scope works independently. For each microscope place a specimen slide in
mechanical stage and move into position for viewing. Use the 4x objective
first. Raise the stage until it will go no higher. Then lower the stage to bring
into focus. Use the fine focus knob to achieve optimum resolution. Once the
image is sharp you should be able to simply turn the nosepiece to the next
objective lens and do minor adjustments with the fine focus knob.
With Coaxial focusing both the coarse and fine focus knobs are on the same
axis. The coarse focus knob is the larger knob located next to the arm of the
microscope. The fine focus knob is the smaller knob mounted on the outside
of the coarse focus knob. Having both sets of knobs on the same axis makes
it easier to switch from one focus knob to the other without removing your
attention from your prepared slide.

The purpose of the condenser lens is to focus the light. The N.A. of 1.25
gives it the ability to be used with higher magnification 100x objective lens
(optional). Movement of the condenser is controlled by a knob. Iris diaphragm
level is located on the bottom of the Abbe Condenser.

The mechanical stage moves the slide on an x - y axis. It consists of a slide
holder and two knobs. The knobs are located on side below the stage. One
knob moves the slide forward and backward. The other knob moves the slide
from left to right.
