Assembly
This microscope comes essentially preassembled; after removing the microscope parts from the protective foam packaging
and checking it over for all components and accessories, final assembly can begin:
Place the stand on a stable counter top.
After loosening the eyepiece set screw, remove the protective black cap; slide the eyepiece into the eyetube, tighten the
eyepiece set screw to secure the eyepiece.
LED Lighting and Power
Connect the power cord to a suitable power supply; turn on the substage illuminator with the ON/OFF switch
located on the right side of the base.
The VanGuard model 1109AML incorporates an internal LED light source for long life and low power consumption. The
LED lamp is designed to last for thousands of hours, therefore routine bulb replacement is no longer necessary.

Focusing Mechanism
Focusing adjustment is achieved by turning the coarse and fine focus control knobs. The large knob is used for coarse
adjustment, while the smaller knob is used for fine adjustment. Focusing tension can be adjusted by turning the focus
tension adjustment ring located just inside of the left coarse focus control knob.
To ensure long life, always turn the focusing knobs slowly and uniformly.

Substage Adjustments
Adjustments to the substage condensing system are crucial for proper illumination and performance. There are three basic
adjustments which need to be made: Centering, Vertical Focusing, and Aperture Adjustment.
Centering: The condenser is factory-centered and fixed and therefore does not require any centering adjustments.
Vertical Focusing: The condenser can be raised and lowered with the condenser adjustment lever to focus the light for
optimal illumination.
Aperture Adjustment: The light path can be adjusted with the iris diaphragm adjustment lever located just below the
condenser. Aperture adjustments are made to induce contrast into a specimen, not to adjust light intensity.
