LED state
Definition
Blinking (2,5
Hz)
The indicator turns on and off with a frequency of 2,5 Hz:
“on” for 200 ms, followed by “off” for 200 ms.
Single flash
The indicator shows one short flash (200 ms) followed by a long “off“ phase (1,000 ms).
Double flash
The indicator shows a sequence of two short flashes (each 200 ms), separated by a short “off”
phase (200 ms). The sequence is finished by a long “off “phase (1,000 ms).
