ALL OFF
"All off" turns off all the devices programmed to the
source buttons at once.
Code
The encoding is done by using different methods varying
the burst and pause duration.
To improve the interference resistance the radiation is
modulated with a frequency of 20 - 70 kHz. The
modulation of the signal reduces the power consumption
of the transmitter and enables the transfer regardless of
ambient light.
Infra red diode
Sends an invisible beam of infra red light at the
wavelength of 880 - 950 nm
LCD (liquid crystal display)
Liquid crystal displays - the liquid crystals are influenced
by the polarisation direction of light, when a particular
amount of electrical voltage is applied.
