Observing through the microscope

• Remove the eyepiece cover (J) from the body tube.

• Place an eyepiece (R/S) into the body tube.

• Turn the coarse focus knob (M) to adjust the height of the stage (E) to

the lowest position.

• Look into the eyepiece (R/S), adjust the brightness of the lamps (G/K)

using the brightness adjustment knob (H).

• Rotate the nose piece (A) to the lowest magniﬁcation power setting.

NOTICE Start with the lowest magniﬁcation power every time a

new slide is placed on the stage (E). Most observations are made at low

magniﬁcation power.

• Clip a slide (not included) or place an object (e.g. a coin) onto the

stage (E), securing with the stage clips (L).

• Without looking into the eyepiece (R/S), turn the coarse focus knob

(M) until the objective lens is close to the slide. The objective lens

should not touch the slide.

• Look into the eyepiece (R/S), rotate the ﬁne focus knob (N) slowly

until the image is clear. Adjust the position of the slide or object if

needed.

NOTICE During slide observations, there is an option to rotate the

diaphragm (F) to enhance the image using color ﬁlters.

• Rotate the nose piece (A) to ﬁnd the correct magniﬁcation power.

Re-adjust the focus using the ﬁne focus knob (N) if needed.

• After using the microscope, remove the slide or object from the stage (E),

take off the eyepiece (R/S) and place the eyepiece cover (J) back on.

Cleaning and Maintenance

CAUTION Risk of damage! During cleaning do not immerse the

product in water or other liquids. Never hold the product under running

water.

Cleaning

• To clean the lenses (R, S, B, C, D), only use lens cleaning tissues. Do
