2-2InstallationSteps BS-6020RF⁄TRF
2-2-1 Installing the Mechanical
Stage Support Device
1. Before installing the device, be sure to
adjust the coarse focus knob①. Make
the guide board ②down to the lowest
position, so you can install the
mechanical stage support device easily.
2. Hold on the mechanical stage support
device (Fig. 2), place it from the top of
the guide board (Fig.1), let the device
(Fig.2) falling free until it reach the limit
position. Use the hexagon wrench screw
down the locking block ③, make the
stage support device and the guide board
fixed together(Fig.3).
The mechanical stage⑤have been
adjusted horizontally and fixed
together before leaving factory. Do
not disassembly unless necessary,
that may affect the observation
precision of the instrument.

microscope body(Fig. 5), and turn to a
proper position, then screw down the bolt
⑥to fix it.
2-2-3 Installing the Video Port
1. Insert the video port (Fig.6) into the
illuminator (Fig. 4), then screw down

left or the right side, then push the
nosepiece clockwise, then place other
objectives by the sequence of low to
high magnification (Fig.7).
