Functions for TETRA digital radios
(SW version 1.02 or higher)
For application in digital radio monitoring of the conversation request tone is necessary. As the Major
mutes its loudspeaker (LS) during transmission, this function has not been available if transmission
is conducted using the gooseneck (GN) microphone.
Thus, in version V1.02 and higher the LS can also stay active during a transmission with the GN
microphone. Circuits, on which no transmission takes place, are muted. Listening to active circuits
(current transmissions) is still possible during transmission. Here, the volume can be reduced.
This function can also be active if the LS would be muted because the handset is taken off.
For transmission using a different microphone (headset, handset or via external input) this option is
not available.
New registers:
270: Circuit 1
271: Circuit 2
272: Circuit 3
273: Circuit 4
Description for all 4 registers:

st
digit:
0 = if SH-PTT is keyed and handpiece is taken off, the LS status depends on
register 016/2
1 = if SH-PTT is keyed and handpiece is taken off, the LS is always active

th
digit: max. volume for SH-PTT: 00000 (LS aus) to 32767 (max. volume)
Here, the listening volume for the circuit is set, the total volume depends on the
overall volume settings
