SAFETY NOTES
1. Open the shipping carton carefully to prevent any accessory, i.e. eyepieces, from dropping and being
damaged.
2. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments.
3. If any specimen solutions or other liquids splash onto the stage, objective or any other component,
disconnect the power cord immediately and wipe up the spillage. Otherwise, the instrument may be
damaged.
4. LAMP REPLACEMENT -- CAUTION: the glass housing of the lamp may be extremely
hot. DO NOT attempt to change the lamp before it is completely cooled or without
wearing adequate skin protection.
5. All electrical connectors (power cord) should be inserted into an electrical surge protector to prevent
damage due to voltage fluctuations.
6. Confirm that the input voltage indicated on your microscope corresponds to your line voltage. The
use of a different input voltage other than indicated will cause severe damage to the microscope.
NOTE: Always plug the microscope power cord into a suitable grounded electrical outlet.
Use only the AC adapter provided with the microscope.
CARE AND MAINTENANCE
1. Do not attempt to disassemble any component including eyepieces, objective housing or the focusing
assembly.
2. Keep the instrument clean; remove dirt and debris regularly. Accumulated dirt on metal surfaces
should be cleaned with a damp cloth. More persistent dirt should be removed using a mild soap
solution. Do not use organic solvents for cleansing.
3. The outer surface of the optics should be inspected and cleaned periodically using an air bulb. If dirt
remains on the optical surface, use a soft, lint free cloth or cotton swab dampened with a lens
cleaning solution (available at camera stores). All optical lenses should be swabbed using a circular
motion. A small amount of absorbent cotton wound on the end of a tapered stick makes a useful tool
for cleaning recessed optical surfaces. Avoid using an excessive amount of solvents as this may
cause problems with optical coatings or cemented optics or the flowing solvent may pick up grease
making cleaning more difficult.
4. Store the instrument in a cool, dry environment. Cover the microscope with the dust cover when not
in use.
5. ACCU-SCOPE®microscopes are precision instruments which require periodic servicing to maintain
proper performance and to compensate for normal wear. A regular schedule of preventative
maintenance by qualified service personnel is highly recommended. Your authorized ACCU-SCOPE®
distributor can arrange for this service.

ASSEMBLY
Your stereo microscope comes pre-assembled. Optional eyeguards are included with your microscope
and can be installed on the eyepieces to help block out extraneous light.
ADJUSTMENT & OPERTATION
Voltage Check
Confirm that the input voltage indicated on the rear label of the
microscope corresponds to your line voltage. The use of a
different input voltage than indicated will cause severe damage
to your microscope.
Connecting the Power Cord (Fig. 1)
Make sure the ON/OFF (I/O) switch ①is turned to the OFF (O)
position. With the microscope facing away from you, make sure
the illuminators are turned off.
To turn the illuminators off: for the bottom illuminator –the dial
on the left side of the microscope ②should be turned all the
way toward the front of the microscope (or away from you); for
the Top illuminator –the dial on the right side ③of the
microscope should be turned all the way toward the back of the
microscope (or toward you).
Insert the power cord into the power receptacle on the back of
the microscope ④; make sure the connection is snug.
Plug the other end of the power cord into the power supply
receptacle.
Input: 100V～240V, 0.15A; 50/60Hz
Output: 4.5V DC; 1000mA
Adjusting Interpupillary Distance (Fig. 2)
Different users have different interpupillary distances (this
distance is between the centers of pupils of each eye). When
operators of the microscope change, it will be necessary to
adjust interpupillary distance.
While looking through the eyepieces, hold the left and right
eyepiece tubes ① of the binocular assembly and adjust the
eyepiece tubes by opening or closing them until the left and right
fields of view coincide completely and you are able to see a
complete circle.

ADJUSTMENT & OPERATION (continued)
Adjusting Diopter Ring (Fig. 3)
Place an easy-to-observe specimen on the stage plate, i.e., a
coin.
Rotate the magnification turret ① to the highest magnification,
then turn the focusing knob ②to focus the specimen.
Rotate the magnification turret ① to the lowest magnification,
looking only into the left eyepiece, adjust the diopter ring ③on
left eyepiece to focus the specimen.
NOTE: The working distance of the microscope is 57mm (the
distance between the microscope objective to the top of the
specimen).
Adjusting the Focusing Tension (Fig. 4)
To adjust the tension, hold both left and right focus adjustment
knobs ①with both hands, hold the left knob (to prevent it from
turning), and rotate the right knob clockwise to increase
(tighten) or counterclockwise to decrease (loosen) the focus
knob tension.
After tension adjustment has been completed, always rotate
both adjustment knobs in the same direction.

ADJUSTMENT & OPERATION (continued)
Changing the Magnification (Fig. 5)
Using the finger grips at the top of the turret ①, rotate the
objective turret until it clicks into place. The magnification of the
objective in the field of view is indicated by the number ②on
the front of the objective turret (facing forward).
Additional magnification ranges can be obtained through the
use of optional 5x, 15x, or 20x eyepieces.
Total Magnification = Magnification of microscope body x
magnification of eyepiece
(i.e., 3x X 10=30x)
Adjusting Illumination (Fig. 6)
The EXS-210 is equipped with a rechargeable variable, built-in
3-way illumination system: LEDs for incident (top) and
transmitted (bottom).
Brightness adjustment: the right brightness adjustment dial ①
is used to adjust the bottom illumination, and the left brightness
adjustment dial ②is used to adjust the top illumination.
Turn the dials to adjust the brightness as needed.
Each dial also has its own on/off so you can use either top
illuminator or bottom illuminator, or both illuminators
simultaneously.

ADJUSTMENT & OPERATION (continued)
Observing a Specimen (Fig. 7)
Turn on the microscope.
Select the appropriate illuminator for the specimen being
observed; there are three modes of illumination:
Incident (top) –for viewing opaque specimens
Transmitted (bottom) –for viewing translucent specimens
Incident & Transmitted –to develop contrasting conditions on
a variety of specimens.
Place a specimen in the center of the stage plate area ①.
While looking through both eyepieces with both eyes, focus the
microscope at the highest power by turning the focus
adjustment knob(s) ②to bring the specimen into focus. This
will keep the specimen in close focus at any magnification. A
slight turn of the focusing knobs may be needed to sharpen
focus.
Recharging the Microscope (Fig. 8)
The LED cordless, rechargeable microscope is completely
portable and be used indoors or outdoors in any location where
there is no electrical outlet access.
The LED cordless microscope is powered by three 1.2v NiMH
AA 1300mAh (Nickel Metal Hydride) rechargeable batteries,
and when used properly can sustain approximately 2 hours
(depending on the light intensity/user) before a charge is
required.
Each microscope is supplied with its own 4.5v/1000A line
cord/charger and would require approximately 8 hours for a full
charge. The life expectancy of the rechargeable batteries is
approximately 10,000 hours or equivalent to 250 recharges
before needing replacement.
NOTE: Your microscope can be used while recharging.
Use ONLY the AC adapter/cord that came with your
microscope.
