LED State
Definition
On
The indicator is constantly on.
Off
The indicator is constantly off.
Flickering
(10 Hz)
The indicator turns on and off with a frequency of 10 Hz: “on” for 50 ms, followed by “off” for 50
ms.
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).
