Several Major 6a´s can be interconnected without any problems as the AF-outputs are only activated
during transmitting and the AF-inputs can be switched to high-impedance by disconnecting jumpers
JMP1 / 1 - 4
(see section
Layout
) .
For this purpose all connections with the individual radio channels (TX-AF, RX-AF, squelch and
transmitter PTT) only have to be connected in parallel circuit (bus- or hub wiring).
The audio-frequency-connection is not integrated in the Major 6a anymore. But by connecting
the external headset-adapter the headset can be used as a combined communicating device for
telephone and radio. The headset is switched to the telephone by an opto-coupler input, which
has to be programmed accordingly (see section Opto-coupler input).
To transmit a call at least one channel has to be activated. If no channel has been selected manually
a signal tone on the loudspeaker draws the user´s attention to the operating error.
Calling by selective call
First at least on channel has to be selected with a selective call. Then the calling code is entered
by using the numerical keys 1 ... 9. The entry is complete when no prompt flashes anymore. The
call is transmitted with the call button and can be repeated with it.
Calling by short dial
The
Major 6a
has 10 codeable short dials per channel. The corresponding short dial for an
activated channel is transmitted by shortly pressing the button
Z
and then entering a number
from ' 0 '...’ 9 ' .
The short dials (channel 1..4) are programmed in the EEPROM-registers x00 - x09 .
Calling by group call
To be able to use the calling system without any restrictions, the special tone ' A ' should be used
as a group call signal. This special tone '
A
' is entered with the button * . The group call tone
can be entered at any position. By pressing the call button the call is started and can also be
repeated by using this button.
