Celestron 44340 Manuel D'instructions page 8

If you do not get an image (or a good image) to view on your LCD screen, here are a few things to double check:
1. Make sure the AC Adapter is plugged in to an AC power source and attached to the microscope securely and correctly.
2. Make sure you have the illuminator turned on with maximum brightness adjustment (this is the normal position).
3. Make sure the objective lens you have chosen is set correctly and it has clicked in the right position.
4. Make sure that the filter wheel is set correctly at a click position so that the illuminated light comes up properly – the normal
position for most usage is with the clear hole.
5. Make sure the specimen slide is correctly fit into the clamp on the mechanical stage and properly centered.
6. If the stage is wobbly or erratic in movement, make sure all screws on the top and side of the stage are tight and especially the two
very small screws to the left of the long stage knob (see Figure 5).
Your Celestron 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 illuminator switch.
Turn off the LCD monitor.
Unplug the power cord.
Always place the dust cover over the microscope when not in use or when being stored.
Store the microscope in a dry and clean place.
Be very careful if using your microscope in direct sun light to prevent damage to the microscope or your eyes.
When moving your microscope, carry it by the "arm" with one hand and not by the focuser knob, LCD monitor, etc. Then, put
your other hand under the base for support.
Clean the outside surfaces (metal and plastics) 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.
Blow off dust with a camel's hair brush or an air blower from optical surfaces.
To clean fingerprints off of optical surfaces, use a lens cleaning agent and lens tissue available at most photo outlets and when
cleaning do not rub in circles as this may cause sleeks or scratches to occur.
Never disassemble or clean internal optical surfaces. This should be done by qualified technicians at the factory or other
authorized repair facilities.
When handling glass specimen slides, use care as the edges can be sharp.
