Definition
Quadruple
Flash
The indicator shows a sequence of four 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).
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
Flickering
The indicator is switched on and off once: 'on' for 50 ms, followed by 'off' for 500 ms.
Double
Flickering
The indicator is switched on and off and on once: 'on' / 'off' / 'on' each for approximately 50
ms, followed by 'off' for 500 ms.
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.
Flickering
