General features
The Major 4a is the newer design of the well-known Major 4. An alphanumeric LC Display with
background lighting has replaced the LED Display. A gooseneck microphone with high dynamics is
new. The programming possibilities have been essentially widened and strongly simpli ed through
a clear text menu structure.
There are two sockets for headsets. One can be used for a remote PTT foot switch. The 7 digital
outputs can be used for remote channel select or for other functions. For operation an external 12-
volt power supply is necessary.
The Major 4a can be programmed via the serial interface or keypad. It is also possible to connect a
printer or terminal on the serial interface. For printers with parallel interface an optional interface is
available.
An ISDN interface is on schedule. The main feature is connecting phone calls to the radio and visa
versa. Of course you can use it also as a normal ISDN phone.

Attention
, do not use PIN 5 to supply a radio,

There are two sockets for connecting a headset.
One is for connecting headset, the other for use
of external PTT-Button.
The digital Pin’s can be con gured as in- or

Connecting Major 4a (5a) --> Two-Way-Radio via multiwire
Connecting Major 4a (5a) --> Two-Way-Radio via multiwire
All audio in/outputs of the Major 4a (5a) are equipped with transformers. No Pin’s are grounded in the
Major 4a (5a); therefore a connection to ground must be made at the two-way-radio side, preferably
by grounding PIN 1 and 8 to PIN 4.
PIN 5 is for supply (+12V) of external devices (LIM-AC, FT634C, FT633AC).
Attention
, do not use PIN 5 to supply a radio, 200 mA output current is not suf cient.
Connecting Major 4a (5a) --> Line Interface LIM-AC
Connecting Major 4a (5a) --> Line Interface LIM-AC
The line interface LIM-AC is connected to the Major 4a (5a) via an 8-wire (Ethernet) patch cable.

The onboard clock is factory

Before changing the values
please note down the current
values.
High values accelerate and low
values decelerate the clock.
Changes made in digital have
more effect than changes made
in analogue.
Fine adjustment must be done in
analogue, step by step.

Hardware con guration
The Major 4a (5a) is for use on 2- or 4-wire line. The
con guration
for 2- or 4- wire is done in register
051/4.
2/4-wire con guration
2/4-wire con guration
2-wire con guration with FT630
For remote control of radio over longer distance it is adviceable to use a 2-wire line with the FT630.
The FT630 transmits and receives the PTT and SQUELCH
status via a DC control voltage.
If there is no DC continuity on the line or if remote channel select is necessary, a FT634C (FT634)
or FT633AC is required.

Key F4 stores the displayed values.
All buttons of the Major 4a can be programmed
with any function. Register 174 and 175 has to
be programmed with the appropriate values of the
short call button (Z-Button).
Register 174 is for use of the functions after short
activation of the Z-Button and register 175 is for
use of the functions after longer activation of the
Z-button.
Register 174 is programmed with 22F01 and
register 175 with 00000.
The  rst zero in register 175 disables action after
long pressing Z-Button.
