It is suggested to hold the Microscope, transparent cover forward, with the thumb held on
the equipment. This holding position offers relative stability and allows lens control. The index finger is
still free to rotate and adjust the focus wheel (as shown).

11
User Manual for Firefly Microscope GT820Version: 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.
