Updates are installed via USB flash drive, no computer software required for the flash step itself. Copy the .KUF update file to a USB storage device. Power the K2700 off, then power it on while holding ENTER to enter System Mode. Go to System Utils > Format Flash to clear old OS data, then System Update > USB Device, select the .KUF file and confirm to load it. When done, power off and back on — verify the new OS/Object versions under Global mode > Info.
