- Open the battery compartment on the base (10) of the microscope.
- Install the two AA batteries (supplied) and close the battery compartment.
VIEWING A SPECIMEN
Stereo microscopes produce a true 3D image of the specimen. Your microscope
includes bug specimens to help you get started.
- Carefully place a specimen in the center of the stage plate.
- Press the power button (9) to turn on the upper illuminator (8).
- Look through the eyepieces and gradually turn the focus knob (7) until the specimen comes into focus.
NOTE: You may need to adjust the interpupillary distance of the eyepieces
for better viewing. Rotate the eyepieces up and down to adjust the eyepiece
distance.
TIP: You can further illuminate a specimen by using an additional source
of lighting such as a desk lamp, table lamp, bright overhead light, or natural
light.
CARE, MAINTENANCE
AND WARRANTY
Your Celestron Labs microscope is a precision optical instrument and should be
treated with care at all times. Follow these care and maintenance suggestions
and your microscope will need very little maintenance throughout its lifetime.
- When you are done using your microscope, remove any specimens left on the stage.
- Turn off the power and unplug the power cord (if applicable).
- Always place the plastic bag or dust cover over the microscope when not in use to help keep it clean.
- Store the microscope in a dry, clean place.
- Be very careful if using your microscope in direct sunlight to prevent damage to the microscope or your eyes.
- To carry your microscope, place one hand on the “arm” of the microscope and the other hand under the base for support. Do not grasp your microscope by the focuser knob or head.
- Clean the outside surfaces (metal and plastic) with a moist cloth.
- Always unplug any cords before cleaning.
- Never clean optical surfaces with cloth or paper towels as they can scratch optical surfaces easily. Instead, use an air blower or camel hairbrush.
- To clean fingerprints off of optical surfaces, use a lens cleaning agent and lens tissue available at most photo supply stores. When cleaning, do not rub in circles as this may cause streaks or scratches.
- Never disassemble your microscope or clean internal optical surfaces. Only qualified technicians at the factory or an authorized repair facility should attempt these repairs.
- When handling glass specimen slides, use care, as the edges can be sharp.
