MICROSCOPE PREPARATION
Check the coarse focus tension. The knobs are oversized and are designed for better gripping. The coarse knob should turn easily to change the focus, but the stage should not move on its own.
For shipping purposes your Prepscope had been shipped with a restraining strap around the microscope, please cut the strap off, as you will not need it again.
Check the stage stop safety feature. Be sure the stage moves up and down when turning the focusing knob. To check the stop first place a prepared slide in position for viewing. Move the coarse focus until the objective and stage are as close together as they can be. Look at the slide and turn the 40x objective into place. This objective should
be very close to the slide, but not touching.
OPERATION
Turn off the power switch, located on the side of the microscope, before connecting the power cord. Bulb replacement can be done from the underneath side. See Bulb Replacement instructions. The

Focus
Place specimen slide under the stage clips into position for viewing. Use the 4x objective first. Raise the stage until it will go no higher. Then lower the stage to bring into focus. Once the image is sharp you should be able to simply turn the nosepiece to the next objective lens and do minor adjustments with the focus knob.
Disk Diaphragm
The rotating disk is located under the stage. (1=smallest, and 5=largest) The different sized holes are used to control the amount of light that is projected upward into the slide. Simply bring one of the different sized holes in line with the stage opening. There is no set rule regarding which setting to use with a particular lens.
BULB REPLACEMENT (model
a. Before changing the bulb, make sure that the power switch is off and the power cord has been disconnected from the wall outlet.
b. On the bottom of your microscope use a slotted screwdriver to remove the screw on the lamp door. Pull open the lamp door and care- fully remove the old light bulb from the socket by gently pushing in and turning the bulb one quarter turn counter clockwise. Using lens paper to hold the bulb, put in new bulb and push and turn clockwise.
c. Avoid touching the glass surface of the bulb with bare hand. Any oil brought onto the bulb by the bare hand will negatively affect the heat
