General/Location

Make sure you position your microscope on a stable, solid surface. An electricity sup-ply is required for observation with the electric illuminator.
Position your device so that it can be disconnected from the power supply at any time. The wall you use socket should be located near the device and easily accessible, since the plug on the power cord serves as a disconnecting device for the power supply. Always pull on the plug to separate the device from the power supply. Never pull on the cord.

Electric LED lighting

Before use, make sure the light switch (16) is set to ‘off’.
The microscope has two light sources. Lighting can be of three types. Set the switch (16) to ‘II’ to light the specimen from above (reflected light) or ‘I’ to light it from below (transmitted light). Use setting ‘III’ to light the specimen simultaneously by transmitted and reflected light. The transmitted light unit (9) is used for transparent specimens (those on glass slides). To view solid, non-transparent specimens, use the reflected light unit (15). Use of both forms of lighting simultaneously is only recommended for semitransparent specimens. This operating mode is not recommended for transmitted light specimens on slides as it may cause reflection on the slide.

Colour filter disc

The colour filter (14) under the microscope table (7) aids in viewing very bright and transparent objects. Just select the right colour for the specimen in question. The components of colourless or transparent objects (e.g. starch particles, single-cell specimens) can thus be better recognised.

Microscope setup

The microscope head (5) will now be prepared for your first observation. First, loosen the screw (21) and rotate the head into a convenient position. Begin every observation with the lowest magnification. Place the microscope’s table (7) with the focus knob (8) into the lowest position and rotate the objective revolver (6) until it locks on the lowest magnification (4X).
NOTE:
Make sure to place the microscope’s table (7) in its lowest position before changing the objective in order to prevent damage to the microscope.
Insert the 10X eyepiece (No. 1, 1) in the Barlow lens (No. 1, 3).
Take care that the Barlow lens is inserted completely into the monocular head (No. 1, 4).

Observation

After you have set up the microscope with the proper illumination, the following prin-ciples are important:

Begin each observation at the lowest magnification, so that the centre and position of the object to be viewed is in focus. The higher the magnification, the more light is required for good picture quality.
Place a permanent slide culture directly under the microscope lens on the plate (7). The specimen to be examined must be directly over the lighting.
Look through the eyepiece (1 and 2) and carefully turn the focus wheel (8) until you can see a sharp picture.
Now you can progress to a higher magnification. Slowly pull the Barlow lens (No. 2, 3) out of the monocular barrel (No. 2, 4). When the Barlow lens is nearly entirely pulled out, the magnification is raised to 2X.
For even higher magnification, you can put the 16X eyepiece (2) into the objective revolver (6) and rotate the objective revolver to a higher magnification (10X or 40X).
TIP:
Depending on the preparation, higher magnifications do not always lead to better pictures.
When changing the magnification of your microscope by changing or adjusting the eyepiece, objective lens or Barlow lens, you must readjust the focus wheel (8) to sharpen the image.
NOTE:
Please be very careful when doing this. If you move the mechanical plate upward too fast, the objective lens and the slide can touch and become damaged.

How do I install the MicrOcular?
Note:
- The MicrOcular only works without the included Barlow lens! The magnification setting is changed when the MicrOcular is used, and it must be readjusted with the focus knob.

  * First, remove the Barlow lens (Fig. 5, 3) with the current eyepiece from the eyepiece support (Fig. 5, 5) and place the MicrOcular (Fig. 6, 4) in the eyepiece (Fig. 6, 5).

How do I install the software?

1. You can download the setup file for installation here: [www.bresser.de/download/CamLabLite](http://www.bresser.de/download/CamLabLite)
2. Start the installation with a double click on the .exe file and follow the instructions of the installation manager.
3. It is not necessary to install a special driver. The camera is automatically recognized by your Windows operating system.

Using the MicrOcular

Preparation

Slide a specimen under your microscope and focus on it.
Remove the eyepiece and Barlow lens from the eyepiece support and the dust cap from your MikrOkular and then install the MikrOkular into the eyepiece support in-stead of the Barlow lens.
Start your PC if you haven‘t yet and connect your MikrOkular to the USB port of your computer.
Start the „CamLabLite“ software and activate the camera by clicking on „USB Video Device.
Click on „Snapshot“ to take a picture or on „Capture“ to record a video.
Click on the floppy disk icon to save the image or capture.

Care and maintenance

Before cleaning, separate the device from the power supply by removing the plug. Only use a dry cloth to clean the exterior of the device.
NOTE:
Do not use any cleaning fluid to avoid damaging the electronics.
Clean the lenses eyepieces and lenses only with a soft, lint-free cloth, like a microfibre cloth.
NOTE:
Do not apply excess pressure to the cloth so as to avoid scratching the lenses.
To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass-cleaning solution and wipe the lenses gently. Protect the device from dust and moisture. After use, particularly in high humidity, let the device acclimatize for a short period of time, so that the residual moisture can dissipate before storing.

Troubleshooting

Error	Solution
No recognizable image	• Turn on light

• Readjust focus

• Check Windows privacy settings

Image flickers (while observing with MicrOcular) = Monitor refresh rate not adequate| • If necessary, increase resolution of graphics card

• Adjust brightness at the dimmer of the microscope

• Disable automatic exposure
