[range 04-16 correspond to 40-160ms]
m – Time of space duration between DTMF tones is calculated up:
(Inserted number) x 10 =pause duration time [ms]
[range 04-16 correspond to 40-160ms]
f – Time of Flash duration is calculated:
Inserted number x 100 = Flash duration time [ms]
[range 1-6 correspond to 100-600ms]
p – Time of pause duration is calculated:
Inserted number x 100 + 400 = pause duration time [ms]
