DE350 Wireless Digital Dermatoscope


To add or remove polarization to the image, twist the nose cone of the device until the desired level of polarization is achieved.

Absolutely. FireflyPro captures .bmp, .jpg, and .AVI files which can be uploaded to most EMR/EHR systems.

The power indicator light should be RED when charging. If the light is flashing red or steady green please make sure you are using the original short USB cable. Using a different USB cable can cause the device to not charge properly.

If that does not work, please try using a computer USB port instead of the AC charger or vice versa. If this does not solve the problem please contact Firefly as you may need a replacement USB cable.

Please close and try restarting the FireflyPro software application again.

Your camera may be experiencing interference from other wireless devices or may have weak signal strength. Please try the following steps:

  1. Look for a wireless channel with less interference by switching the wireless channel on both the camera and wireless receiver.
  2. Do not cover the back of the camera with your hand. This is where the antenna is located.
  3. Do not place the wireless receiver under metal desks, inside metal cabinets or near metal furniture.
  4. Eliminate as many physical obstacles as possible between the camera and the wireless receiver.
  5. Recharge the camera to strengthen its power output.
  6. Move 5.8GHz cordless phones away as they may cause interference.
  7. Tilt the wireless receiver up and down for better reception.
  8. Sometimes the receiver is getting too hot due to lack of proper ventilation, please improve the flow of air around the receiver to cool it down.

There are a few ways this issue could be resolved –

  1. Please press the settings icon and select the correct model number. Once selected, re-launch the FireflyPro software.
  2. Verify the LEDs are illuminated and the brightness dial on the side of the camera is at its maximum setting.
  3. Try changing channels on the receiver and the device. Also, make sure your hand is not covering the back of the device – This can hinder the wireless signal

If your setup requires a hub or multiple Firefly devices plugged into the same machine, please contact us to help with the configuration.


Yes. Please click HERE to download FireflyPro for Mac, then follow the instructions on the download page.

Note – The software requires OSX v10.8 or later running on Intel. Power PC based systems are not supported.

The FireflyPro software installation includes two main components:  The FireflyPro application and the device driver that allows the PC to recognize and control the Firefly device. The error message can be due to one of the following:

1. You do not have administrator privileges on the PC. Please re-install FireflyPro as an admin.

2. For software versions prior to version 1.50 – You may have accidentally installed the DE500/DE501 or other wired device software instead of the DE550/DE551 or other wireless device. Please download our new software version HERE. Save the file on your computer and install it by double clicking the file and follow the installation screens.

3. You plugged the wireless receiver in before installing the FireflyPro software. Please remove the receiver and install the software first.

4. You plugged in the receiver and immediately launched the FireflyPro software. On some computers (when you plug in the receiver for the first time) it takes about a min for the PC to recognize the new device and associate the driver to it. Please remove the receiver, plug it again and wait for the PC to recognize and install the device. Then launch FireflyPro application.

The problem might be related to the PC virtual camera. On some PCs the virtual video/webcam driver doesn’t allow other cameras to operate. This must be disabled in order for Firefly devices to work properly. Please try the following:

  1. Check to see if there is a virtual camera icon on the windows desktop system tray (on the bottom right side of the screen). If so- right click on it and disable it.
  2. Go to control panel, select “programs and features” and look for virtual camera or webcam. If one is present you will need to disable it.
  3. In control panel select “device manager” and then “Imaging Devices” to expose all cameras in the system. Here, please right-click on the webcam and disable it. Also, if you see virtual camera, disable that as well.

Now that the the system no longer has an active virtual camera, try running the FireflyPro software. (You may need to re-install FireflyPro.)

Turn on the camera and confirm the wireless receiver and the camera are on the same channel. If you still don’t see an image the camera’s battery may be drained Please charge the device for at least 30 minutes and try again.

No. The only caveat is that the pictures’ default name is based on a date. So if you keep the default names, pictures from the specific upgrade date may be overwritten.

Please unplug the wired product or wireless receiver from the computer and follow these steps:

  1. From the “start” menu select “Control Panel” and select “programs and features”. (For XP – “add and remove programs”)
  2. Click on FireflyPro and select “Remove” from the top of the window.
  3. When prompted with “Do you want to completely remove the selected application and all of its features?” Select “Yes”.
  4. Wait until the FireflyPro icon disappears from the list.
  5. On the “program and features” list, find “Digital Microscope” and select “Remove”. If “Digital Microscope” is not on the list, please proceed to Step 8 below.
  6. When prompted with “Do you want to completely remove the selected application and all of its features?” Select “Yes”.
  7. Follow the un-installation screens.
  8. Please restart the computer.

Please connect receiver to the PC and wait until it is recognized by Windows. When ready, double click on the FireflyPro icon to launch the software.
