How can I turn off the blinking status LED on Canton Smart devices (speakers and amplifiers)?

After integrating the Canton Smart product into the Wi-Fi and setting up Google Cast, the LED will stop blinking and light up continuously green. This is a requirement from Google. If you do not want to set up the device, you can turn off the blinking LED in the "System Settings" (SYS) menu under "Display Settings" (UIS) at "LED Blinking" (LED) to "OFF". Then the LED will light up red/green instead of green to indicate that the device is not set up.
