User Manual for Firefly Microscope GT820 Version: 2.0
High zoom use:
When there is a need for high zoom, maintaining body stability becomes more paramount. In such
instances, it is suggested that the digital Microscope focus wheel opening should be placed towards
the user
, and
the transparent cover vertically downward. This enables easy access to the focus wheel and
a very stable position. (Shown below
)
Device vertically downward (stable observation)
Focus
：
Based on the relative height of the observed object, the focus wheel can be turned for a clear image.
When a higher magnification is required, the focus wheel can be turned to the left (see below). If a larger
field of view is required, the Microscope can be moved farther away and the wheel turned to the right.
