6.2 Human body induction trigger
The human body induction is triggered only when there is no any other operations. When the human body
induction is triggered, open the relay, and start timing its delay time. In the process of playing, green LED indicator
light is on all the time; after finishing playing, light off. After ending the voice play, if it is not the relay off-delay time,
the relay will be still closed. Within the relay closure time, red LED indicator flashes with 2-second cycle. If there is
voice triggering within the relay off-delay time, the time will be cleared, and red LED is no longer flashing; relay
still keeps working. Besides, the relay is switched off without triggering operation within the relay off-delay time.
