The LED backlight on the microphone constantly lights with the call station initializa-
tion, as well as during the pushbutton press to transfer voice information from both the
microphone and with a sound fragment translation, duplex connection including. With the
input simplex call and with the manual duplex control or unilateral telephoning control, the
backlight flashes with the rough period of 0,6 sec during the input call translation to the
built-in loudspeakers.
