There are two sockets for a headset. The
headset is connected to ST13 and an external
PTT-button (e.g. a foot switch) can be connected
to ST12 or ST13.
All sockets of the Major shown from rear view.

output +12V, max. 200mA 5
PTT active low 6
TX-AF-output (Mod +) 7
TX-AF-output (Mod -) 8
The AF- in/outputs are equipped with transformers
and therefore are potential-free. An external device
(FT630-2, FT6304aC) can be powered with contact
5 (+12V) .
Attention
: 200mA are not suffi cient for a radio.

For protocolling a printer can be connected to
the RS232.
The serial interface can be
laid out as RS485 (option)!
