4. Focusing and dioptre compensation
Set the dioptre scale (2) to „0“ and observe an object. Now close your left eye and adjust the focus
with the focuser (4) for your right eye. Then, close your right eye and adjust the focus for your left
eye with the dioptre scale (2). Now, the microscope is adjusted for your eyes. Note the setting of
the dioptre scale you need to use in future.
5. Eye distance
The Researcher ICD is equipped with an adjustable binocular head. To set your eye distance,
move the eyepieces against each other until you found the ideal position.
6. Replacing the Eyepieces
To replace the eyepieces you need to loosen the clamp screw on the underside of the eyepiece
holder (17). You can then easily remove and replace the eyepieces.
The clamp screws serve only as protection so that the eyepieces will not fall out.
Note:
The LED illumination has a life span of approx. 20,000 hours. In the case of a technical error please
contact the service center.
7. Adjusting the friction of the focusing drive
It can happen that the Microscope head is no longer held by the focusing drive and shuts down
because of his net weight.
With the BRESSER Researcher ICD you can adjust the friction with the enclosed wrench (19).
The wrench is simply hooked into two holes of the wider shaft (18). By rotating you can adjust the
friction strongly or lightly.
8. Replacing the rechargeable batteries
In the case the batteries become defective, they can be replaced by new ones. Open the Battery
section at the underside of the microscope and put three new rechargeable batteries (16) (Type
NiMH AA 1.2V, ca. 1200 mAh) in place (4). Please take care of the correct position!
CAUTION:
DO NOT use non-rechargeable batteries. This may cause fire and/or explosion!
9. Cleaning and maintenance
Your microscope is a high-quality optical instrument. Please take care that neither dust nor
fingerprints take place on the optical surfaces. If necessary, clean the microscope body with a
slightly moistened soft cloth. Use a separate clean cloth with some drops of alcohol to clean the
optical surfaces. After using, the microscope should be protected with its dust cover.
Note:
Please consider that a sufficient treated microscope keeps its value and optical quality for many
years.
