5. Use an electrical surge suppressor to protect the microscope from voltage fluctuations.
6. When replacing the LED bulb or fuse, ensure the main switch is off, disconnect the power cord, and wait for the bulb and lamp house to cool down.
7. Ensure the input voltage matches your line voltage to avoid severe damage to the microscope.

Care and Maintenance:

1. Do not attempt to disassemble any component of the microscope.
2. Regularly clean the microscope to remove dirt and debris. Use a damp cloth for metal surfaces and a mild soap solution for persistent dirt. Avoid using organic solvents.
3. Store the microscope in a cool, dry environment and cover it with the dust cover when not in use.

Unpacking and Components:
Your microscope is pre-assembled and packed in a molded container. To unpack it:

1. Handle the microscope by its arm and base.
2. Place the microscope on a flat, vibration-free surface.
3. Retain the molded container for future reshipment.

SAFETY NOTES

1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from dropping and being damaged.
2. Do not discard the molded Styrofoam container; the container should be retained should the microscope ever require reshipment.
3. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments. Ensure the microscope is located on a smooth, level, and firm surface.
4. 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.
5. All electrical connectors (power cord) should be inserted into an electrical surge suppressor to prevent damage due to voltage fluctuations.
6. For safety when replacing the LED bulb or fuse, be sure the main switch is off (“O”), remove the power cord, and replace the LED bulb after the bulb and the lamp house have completely cooled.
7. 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.

CARE AND MAINTENANCE

1. Do not attempt to disassemble any component including eyepieces, objectives or 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 stream from an air bulb. If dirt remains on the optical surface, use a soft 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 such as cotton swabs or Q-tips, 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. Oil immersion objectives should be cleaned immediately after use by removing the oil with lens tissue or a clean, soft cloth.
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 that require periodic preventative maintenance to maintain proper performance and to compensate for normal wear. An annual schedule of preventative maintenance by qualified personnel is highly recommended. Your authorized ACCU-SCOPE ® distributor can arrange for this service.

ADJUSTMENT & OPERATION

Connecting the Power Cord

• Make sure the power switch is at “0”(OFF) before connecting.
• Insert the connector ① of power cord securely into the power socket ②.
• Insert the other connector securely into an electrical outlet.
• The microscope uses a universal power supply so it may be used in any voltage range between 90 ~ 240v when used with the appropriate line cord.
• IMPORTANT: Use care when storing the power cord so that it does not bend or twist – it is recommended to wrap the cord around the cord hanger for storage.

Illumination

• With the microscope turned on (I), rotate the light adjustment dial ① until the illumination is comfortable for observation.
• Rotate the light adjustment knob toward the back of the microscope to increase brightness; rotate toward the front to reduce brightness.

Placing the Specimen Slide

For Models With a Fixed Stage

• Place the slide on the stage with the cover glass facing up and secure it with the stage clips ①.

For Models With a Mechanical Stage

• Push the slide finger ② of the specimen holder towards the back to open it and place a specimen slide into the slide holder with the cover glass facing up. Release the slide finger so it closes and secures the slide in place.
• Rotate the X and Y-axis knobs ③ to move the slide into position.

Adjusting the Focus

• Turn the coarse adjustment knob ④ counterclockwise to move the stage to its lowest position.
• Place a specimen slide on the center of the stage.
• Using the 4x objective bring the specimen into focus using the coarse ④ and fine ⑤ focusing controls.
• Different objectives can be brought into view by rotating the nosepiece and using the fine adjustment knob because the objectives are parfocal.

Using the Disc or Iris Diaphragm

• Each EXM-150 Series Microscope is supplied with either a disc or iris diaphragm, depending on the model ordered.
• The amount of light can be adjusted by opening or closing the iris diaphragm (using the lever ①) or by turning the disc diaphragm ②, located just beneath the stage).
• Adjust the diaphragm to the smallest size allowable for a clear, sharp image of the specimen.

Using the Darkfield Stop (optional)

• To view specimens using the Darkfield Stop, rotate the stop into the closed position.
• While viewing a specimen, adjust the iris diaphragm open or closed to optimize the image. The specimen should appear mostly white on a dark background.
• To view the specimen in brightfield mode, rotate the darkfield stop into the open position.
• NOTE: The darkfield stop is only available with the iris diaphragm.

Using the 100xR Oil Objective
(EXM-151 Models ONLY)

• The procedure for examining a specimen using an oil immersion objective is as follows:
• Rotate the nosepiece so the low-power objective is in the optical path.
• Place one drop of immersion oil on the lighted area of the specimen slide ④.
• Rotate the nosepiece so the 100xR oil immersion objective is in the light path. Dust or air bubbles in the oil can destroy the definition of the image. If the bubbles are trapped between the objective lens and the slide, clean off the oil and start again, or try to eliminate the bubble by rotating the objective back and forth.
• With your eye at the level of the stage, use the coarse focus knob to raise the stage with the specimen cover glass. When you see a flash of light at this location the objective lens has made contact with the immersion oil and the microscope can now be focused using the fine focus knob.

IMPORTANT NOTE

• Each time you finish using the oil immersion objective wipe off all traces of oil from the objective and the specimen cover the glass with a lens tissue or clean, soft cloth.
• Cleaning after each use will prevent oil from contaminating the high dry objective (40xR), prevent dust and dirt from accumulating on the lens of the objective which will degrade its optical performance, and will keep the slide clean to work with.

Recharging the Microscope

• 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 AA 1300mAh 1.2v NiMH (Nickel Metal Hydride) rechargeable batteries, and when used properly can sustain approximately 4 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 requires approximately 8 hours for a full charge. The life expectancy of the rechargeable batteries is approximately 20,000 hours or equivalent to 400 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 Fuse

• Turn the main switch to “0” (OFF) before replacing a fuse.
• Unplug the power cord from the microscope.
• Carefully place the microscope on the back of its arm so the bottom of the microscope base is facing toward you.
• Screw off the fuse holder ① from the bottom of the microscope with a flat-head type screwdriver ( — ).
• Gently pull out the old fuse ② and Install a new fuse into the fuse holder and screw it back into the base.
  • Specification of the fuse: 250V, 1.0A CAT #3277-1

Replacing the Rechargeable Batteries

1. Unplug the microscope from the electrical outlet (if plugged in) and unplug the charger from the rear of the microscope (if plugged in).
2. Carefully place the microscope on the back of its arm so the bottom of the microscope base is facing toward you.
