Definition
Blinking
(2.5 Hz)
The LED turns on and off with a frequency of 2.5 Hz: “On” for 200 ms,
followed by “Off” for 200 ms.
Single flash
The LED shows one short flash (200 ms) followed by a long “Off“ phase
(1,000 ms).
Double flash
The LED 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).
