INSTRUCTION MANUAL

How do I use my microscope?

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 transferring it. 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 microfibre 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.

How do I operate the illumination?

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 colour

filter wheel is located in the middle of the microscope stage. The filters help you when

you are observing very bright or clear specimens. Using these filters, you can choose

various brightness levels and colours. This helps you better recognize the components of

colourless or transparent objects (e.g. sea salt).

How do I adjust my microscope correctly?

Place the microscope in a suitable location as described above, and sit in a comfortable

viewing position. Always start each observation with the lowest magnification. Adjust

the distance of the microscope stage so that the stage is in the lowest position, farthest

away from the turret head. Turn the objective turret until it clicks into place at the lowest

magnification (Objective 15x / 300x). Note: Before you change the objective setting, always

make sure the microscope stage is farthest away from turret by rotating the focus knob.

Separating the stage and turret by rotating the focus knob will avoid causing damage to

the specimen slide or microscope. When starting an observation, always start with the

15x / 300x objective in the rotating head.
