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.

INTRODUCTION

microscopes are engineered and manufactured to the highest quality standards. Your microscope will last a lifetime if used and maintained properly. ACCU- SCOPE Congratulations on the purchase of your new ACCU-SCOPE® stereo microscope. ACCU-SCOPE® microscopes are carefully assembled, inspected and tested by our staff of trained technicians in our New York facility. Careful quality control procedures ensure each microscope is of the highest quality prior  to shipment.
UNPACKING AND COMPONENTS
Your microscope arrived packed in a molded shipping carton. Do not discard the carton: the shipping carton should be retained for reshipment of your microscope if needed. Avoid placing the microscope in dusty surroundings or in high  temperature or humid areas as mold and mildew can form. Carefully remove the microscope from the shipping carton and place the microscope on a flat, vibration-free surface.

COMPONENTS DIAGRAM

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 ① is 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 ② should 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  ③ of 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.

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 ② to focus the specimen.
Rotate the magnification turret ① to the lowest magnification, looking only into the left eyepiece, adjust the diopter ring ③ on 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 ① with 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.

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 ② on 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 ② is 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.
For more information about the rechargeable LED illumination system and replacing the rechargeable batteries, please refer to pages 8-9.

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) ② to 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.

Replacing the Rechargeable Batteries (Fig. 9)

1. Unplug the microscope from the electrical outlet (if plugged in) and unplug charger from rear of microscope (if plugged in).
2. Carefully place the microscope on the back of its arm so the bottom of the microscope base is facing towards you.
3. Open the trap door on the bottom using a small Philips head (+) screw driver.
4. Replace the three NiMH AA 1300mAh rechargeable batteries.
5. Close the trap door, and place the microscope in an upright position.
6. Plug the charger to the power receptacle on the back of the microscope and plug into an electrical receptacle for continued use while charging.

Allow the LED microscope to charge for 8 hours before using as cordless.

IMPORTANT
USE ONLY 1.2v NiMH AA 1300mAh (Nickel Metal Hydride) rechargeable batteries in your microscope.
Using any other type of battery may damage to your microscope.

Replacing the LED Bulbs
The reflected (top) and transmitted (bottom) lights can be used simultaneously. The lux rating for the reflected illuminator is 7000lux, and the transmitted 18,000 lux by a distance of 70mm.
The life expectancy of the LED bulbs is 20,000 hours. The LED bulbs are covered by a 1 year manufacturer’s warranty.
