3.1 First time use
Before installing and using the biological microscope, make sure to read the Safety Instructions (See Chapter 1) carefully.
When unpacking and handling, please do not touch the optical surfaces.
3. FIRST TIME USE & OPERATION
• After unpacking, place the biological microscope on a flat workbench and remove any foam padding or spacer
used to prevent vibration during transportation.
• Connect the cable at the base to the power supply. Before plugging in, keep in mind that the working voltage
of the biological microscope shall be the same as the supply voltage. (Figure 1)
• Turn on the power switch at the back of the base. (Figure 2)
Note: Make sure that the brightness control is in the minimum position before turning on or off the power switch.
• Rotate the brightness control to the desired illumination. (Figure 3)
• After use, turn the brightness control to the minimum position, and then turn off the power and put on the dust-
proof cover.
• The coarse focus tension (Figure 4) has been set at the factory, but can be readjusted as required
(see figure 4, number 1).
