To update the software via USB, first upload appropriate driver from our "drivers" section. You should download a file named: sky25settings.sky.
Then copy the update file ("sky25firmware.sky"), the system settings file ("sky25settings.sky") or/and reset password file ("sky25resetusers.sky") into the root of USB-flash drive. Do not change the file names!
Insert USB flash drive into the input "USB" and wait while the contents of drive will be analyzed by the device.
The process of updating will be displayed on the LED on the front panel of the device.
After the system is rebooted (all the LEDs will be turned off) test the system.
