Encoder
Major BOS V
has an integrated encoder for
call 1
and
call 2.
The calls for each channel
are transmitted directly with the corresponding buttons on the keyboard (
I / RUF 1
or
I /
RUF 2
). The calls are transmitted as long as the corresponding button is being pressed.
Transmitter Control
The transmitters of the selected radio channels are activated with one of the PTT but-
tons (e.g. handset or headset) and stay activated as long as the PTT button is being
pressed. During transmission of call 1/2 the corresponding transmitters are automatically
activated.
It is always possible to transmit on non-activated radio channels by using the red PTT
buttons on the control panel. The assignments of the buttons to the channels can also be
customized (Web Interface).
Connection to Telephone AF
The audio-frequency connection is not integrated in the
Major BOS V
anymore. But by
connecting the external headset-adapter the headset can be used as a combined com-
municating device for telephone and radio.
The headset is switched to the telephone by an opto-coupler input, which has to be
configured accordingly.
Microphone Selection
For each of the 3 PTT inputs it is possible to program the corresponding microphone
individually via the
Web Interface
.
Additionally there are
two
ways of automatic headset detection:
- the Major BOS 8a can detect if a headset is connected by measuring the headset
supply voltage (see
Web interface
).
- one of the inputs can be configured as headset detection (headset is connected if
input is activated, i.e. connected to GND)
If the Major BOS 4a has detected a headset then all buttons programmed as SH/HS-
PTT use the headset microphone. Otherwise they use the gooseneck microphone.
