OPERATION

Model AY11228
1. Remove components from package. identify all parts before assembling.
2. Tighten the knob on the stand to prevent the elevator from sliding down.
3. Fix the binocular body on the stand with the tightening screw.
4. Check the input voltage to ensure that it conforms to the microscopes requirement.

SELECTING THE ILLUMINATION
1. Depending on microscope use, select oblique or transmitted illumination.
2. The Brightness Adjustment Knobs change the oblique or transmitted light independently. The transmitted illuminator fluorescent lamp cannot be adjusted.
3. The angle of the oblique lamp can be adjusted to ensure optimum lighting of the sample.

2. The Brightness Adjustment knobs change the oblique or transmitted light independently. The transmitted illuminator fluorescent lamp cannot be adjusted.
3. The angle of the oblique lamp can be adjusted to ensure optimum lighting of the sample.

CHANGING THE INTERPUPILLARY DISTANCE
1. The distance between the observer's pupils is the interpupillary distance.
2. To adjust the interpupillary distance rotate the prism caps until both eyes coincide with the image in the eyepiece.
