hours continuous operation.
◼Charging the Battery:
Through the micro-USB port at the rear of the dermatoscope, the embedded battery can be charged with
the provided USB DC cable. The cable must be connected to the USB port of a PC or to the “USB Power
Adapter”, which can charge directly from a wall outlet.

Recommended Holding Position:
It is suggested to hold the dermatoscope, transparent cover down, 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).
Focusing:
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 focus wheel turned to the
right.

High Magnification Use:
When there is a need for a higher magnification, 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. A smooth desktop may be used as an observation platform. (Shown below)
Using the Image and Video Capture Controls:
Press and release the Snapshot button to capture image frames. The system will generate a shutter sound
from the speaker as confirmation. Press and release the Video Recording button to record video. The
system will not generate any sound when the video recording button is pressed.

MAINTENANCE AND SERVICE
Cleaning and Care Recommendations
The Firefly digital dermatoscope is designed to provide years of service if it is maintained properly. Proper
cleaning and gentle usage are critical to ensure that the device will continue to work reliably.
The dermatoscope cannot be sterilized and should not be submerged in liquids or subjected to steam
sterilization or other sterilization methods.
The exterior of the device and its clear plastic nose cone may be cleaned with a lint-free cloth soaked in an
alcohol solution. Alternatively, CaviWipes or similar disinfectant wipes can also be used. Please refer to the
directions provided by the manufacturer of the wipes for appropriate instructions for use.
Wipe down the exterior of the device, cleaning all external surface areas. Care should be taken to prevent
excess liquid from seeping into the internal components.
Remove the clear plastic nose cone and wipe as described above. Additionally, the nose cone can be soaked
in alcohol or other disinfectant solutions while not attached to the device.
Do not apply alcohol, chemicals, or water to the lenses. Solutions entering the optical assembly could
damage internal components.
The dermatoscope should be stored in a safe location where it will not be subject to sudden impacts. Care
should also be taken not to drop the device on a hard surface as this may damage the optical assembly as
well as other internal components.
