+ | | ||
+ | * turn on all devices as the same time | ||
+ | * within 10 seconds, while RF LED is blinking, press and hold button on one of the devices | ||
+ | * after a second, the new address is randomly generated and sent to all devices. RF LED will blink 3 times to confirm the new address. | ||
