Firmware Update
Embedded software of the Q-NRG device (also known as “firmware”) can be updated by the user using an USB
flash drive. Firmware update on the Q-NRG allows a user, with proper credentials, to upgrade or reinstall the device
firmware.
Prepare the USB flash drive device
The USB storage device used to update Q-NRG firmware must be prepared to be recognized by the update
procedure. On average, the firmware update file size is about 500MB; the only requirement is that such file fits on
the USB storage device used to update (be sure to have free space on the USB storage device).
Note
:
The USB storage device must be formatted as FAT32 file system (32 GB Max storage size)
1. Check www.cosmed.com for firmware updates and send your upgrade request
2. Download the upgrade file received from COSMED.
3. Connect the USB flash drive device to the host PC.
4. Extract the downloaded zip file content to the root directory of the USB flash drive device (e.g.: E:\, do not
select sub-folder).
Other files, besides the firmware update file, can be present in the file system. The firmware update procedure does
not write anything to the USB flash drive device, therefore every file is left unchanged.
Install Firmware
