User Manual for Firefly Microscope GT830 Version: 1.3
Using the Polarizer:
The GT830 is equipped with an integrated polarizer feature. To activate polarization, turn the black ring
behind the nose extender. Multiple degrees of polarization may be achieved by gradually turning the
polarizer ring from 0degrees to 360degrees.
Standby and Remove device:
To temporarily turn off or remove the device, slide the power button to
the “OFF” position. The device must also be turned off through the
Windows operating system:
On your Microsoft Windows Desktop, click My Computer in the left
pane. Double-click the USB Video Device (Digital Microscope in
Windows Vista and Windows 7).
After turning off the device through Windows above, it can be unplugged from the
PC’s USB port. Using this sequence will avoid transient voltages from potentially
causing hardware damage.
