SAFETY NOTES 

1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from dropping

and being damaged.

2. Keep the instrument out of direct sunlight, high temperature, humidity, and dusty environments.

3. If any specimen solutions or other liquids splash onto the stage 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.

FUSE REPLACEMENT

 -- For safety when replacing the fuse (ONLY replace with the same

size, type and rating of original fuse), be sure the main switch is in the off position, disconnect

the power cord from outlet, and replace the fuse.  Reconnect the power cord and turn unit on.

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.

NOTE:  Always plug the Microscope power cord into a suitable grounded electrical outlet.

A grounded 3-wire cord is provided.

CARE AND MAINTENANCE

 

1. Do not attempt to disassemble any component including eyepieces, objectives 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
