User Manual for Firefly Wireless Microscope GT620 Version: 2.0
Charging Battery:
Duration:
The Wireless Firefly Microscope has a built-in high efficiency lithium battery that enables more
than 3 hours continuous operation.
Charging the Battery:
Through the mini-USB port at the rear of the Microscope, 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.
Overload Protection:
The overload protection circuit will prevent overcharging when the battery is full and the
“Indicator” will turn green.
Power Indication:
The power indicator light is normally red during operation, but it will turn blue when the
remaining battery life is less than 30 minutes.
The lithium battery is a delicate and consumable item. It is expected to last through years of
use and is guaranteed for twelve months from its purchase against defects. If there is any
battery related issue, please contact customer service immediately. Battery replacement by
unauthorized personnel or replacement with unauthorized batteries may damage the system and
voids the overall warranty.
Channel Mapping:
On the rear right side of the Microscope, there is a switch allowing users to set the
wireless channel. Both the receiver and Microscope must be set to the same
channel for proper operation:
CH 1: Channel 1
CH 2: Channel 2
CH 3: Channel 3
CH 4: Channel 4

User Manual for Firefly Wireless Microscope GT620 Version: 2.0
Using the Firefly Microscope System:
Recommended holding position:
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).

13
User Manual for Firefly Wireless Microscope GT620 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. A smooth desktop may be used as an observation platform. (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 focus wheel turned to the
right.

14
User Manual for Firefly Wireless Microscope GT620 Version: 2.0
Brightness Adjustment:
On left rear side of the Microscope, a knob allows the user to control the
brightness of the LEDs:
Backward Turn: Decrease Brightness
Forward Turn: Increase Brightness
Using Focus:
Default Position: Match the scale 50 to arrow mark.
Using the image capture control:
Press and release the Capture button to capture image
frames. The system will generate a shutter sound from the PC
speaker as confirmation.

User Manual for Firefly Wireless Microscope GT620 Version: 2.0
Using the Polarizer:
The DE300 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, push and release the power
button to the “OFF” position. The device must also be turned off

Device (Wireless Digital Microscope in Windows Vista and Windows 7)
After turning off the device through Windows above, the
compact receiver can be unplugged from the PC’s USB port.
Using this sequence will avoid transient voltages from
potentially causing hardware damage.
