The filters help  you when you are observing very bright or  clear specimens. Using these filters, you can  choose various brightness levels and colors.  This helps you better recognize the compo- nents of colorless or transparent objects (e.g.  grains of starch, or protozoa). Place the microscope in a suitable location as  described above, and sit in a comfortable view- ing position. Always start each observation with  the lowest magnification. Adjust the distance of  the microscope stage (Fig. 3) so that the stage  is in the lowest position, farthest away from tur- ret head. Turn the objective turret (Fig. 7) until it  clicks into place at the lowest magnification (Ob- jective 15X/300X). Note: Before you change the  objective setting, always make sure the micro- scope stage (Fig. 3) is farthest away from turret  by rotating the focus knob (Fig. 2). Separating  the stage and turret by rotating the focus knob  will avoid causing damage to the specimen slide  or microscope. When starting an observation, al- ways start with the 15X/300X objective (Fig. 7) in  the rotating head (Fig. 3). Quick Fact — The highest magnification is  not always the best for every specimen! Locate the mirror/light on the base of the  microscope. Flip the mirror/light to the on  position (with the light facing up) and the light  will illuminate. This microscope is equipped  with an incandescent light that illuminates  the specimen from below. The color filter  Once the microscope is in a suitable location  and the batteries are installed, check the light  source to make sure that it illuminates. Use  a microfiber cleaning cloth to gently wipe the  lenses off. If the stage is dirty with dust or oil,  carefully clean it off. Make sure that you only  raise and lower the stage using the focus  adjustment knob. Install two “AA” batteries (not included) in  the battery box, located in the base of the  microscope. Remove the rubber base with a  screwdriver, and insert the batteries accord- ing to the displayed +/- information. Reattach  the rubber base with the screw. Before you use your microscope, make sure  that the table, desk, or surface that you place  it on is stable and is not subject to vibration.  If the microscope needs to be moved, hold it  by the arm and base while carefully transfer- ring it. get the greatest benefit from your precision in- strument.
