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 simplifi 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 12volt 

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.

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 suffi cient. 

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.

Hardware confi guration 

2/4-wire confi guration 

The Major 4a (5a) is for use on 2- or 4-wire line. The confi guration for 2- or 4- wire is done in register 

051/4. 

2-wire confi 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 fi rst zero in register 175 disables action after 

long pressing Z-Button. 

- 10 - 

The digits in register 174 activate the following 

functions: 

1. digit = 2 --> function 2 - transmit call 

sequence 

2. digit = 2 --> short dial 

3. digit = F --> input necessary 

4. digit = 0 --> 5 tone sequence 

5. digit = 1 --> not applicable 

Follow the next steps to view or change the values 

in register 174 and 175.

Funk Tronic Major 4a 



Individual programming of the buttons 

It is possible to program each button of the Major 

4a with two different functions. 

The key down time selects the function. Pressing 

the button shorter than one second activates the 

functions listed for „short press“ and pressing 

the button longer than one second activates the 

functions listed for „long press“. 

The short press function is activated immediately, 

if long press is not programmed. 

Each register has 5 digits. The fi rst digit selects 

the function (on or off). Digits 2 to 5 depend on 

the function programmed in the fi rst digit. 

Example for programming button - 1. 

Programming „short press“:

È 

Register: 132 

Code 71100 

1 st digit 7 = function --> enter select number 

2 nd digit 1 = new input 

3 rd digit 1 = delete only last input 

4 th digit 0 = not applicable

Encoder prefi x 

Register 010 defi nes the number of permanent 

programmed prefi x digits of the encoder. 

If „FFFFF“ is programmed in register 010, all 5 

digits have to be entered via the keypad. 

For example, if digit 1, 2 and 4 are permanent and 

digit 3 and 5 have to be entered via the keypad, 

register 010 must be programmed with 34F5F. 

Switching of the input promt „select number“ is 

established with EEEEE. 

Example of entering all 5 digits via the keypad:

Transmitting 6/7/8-tone 

Sequences 

To transmit an 8-tone sequence, the following 

programming is necessary. The fi rst 5 digits are 

entered via the keypad, and the last 3 are used 

from register 015. 

Register 172:

Code 20050 

2 = transmit call sequence 

0 = entered call 

0 = not applicable 

5 = 8 tone sequence 

0 = not applicable 

The 8-tone sequence is combined from the 5 digits 

entered via the keypad and the last 3 digits from 

register 015 (Personal identifi cation code).

Channel scanning function 

The channel scanning function is activated if the 

waiting time in register 067/5 is programmed NOT 

to be zero. Zero deactivates this function. 

The scanner will wait for at least the programmed 

waiting time per channel. Just before the end of 

the waiting time, the channel is checked for a 

carrier. If no carrier is detected the next channel 

will be scanned. 

Scanning will stop when a carrier is detected 

‘if scanner stop on carrier’ (register 068/1) is 

programmed. If not the scanner will be stopped 

for an additional 100 ms. During this time the 

scanner will scan for a tone. If a tone is detected, 

the scanner will wait for the scan waiting time as 

programmed in register 068/2+3rd If no tone is 

detected scanning will continue. 

The channel range programmed in register 067/1-4 

will be scanned. If register 067/1+2 is programmed 

with ‘EE’ the specifi ed channels programmed in 

register 070-074 will be scanned. 

The end of the table is marked with FF. 

For example, if channels 1, 5 and 6 should be 

scanned, register 070 is programmed with 0105x 

and register 071 with 06FFx. 

The scanner is triggered by a carrier and PTT 

and stops scanning during the programmed 

loudspeaker time (050/1-3). 

Scanning will continue after hanging up the 

handset, if register 050/5 is programmed 

accordingly. 

The scanner will switch off if the loudspeaker (LS 

button) is activated manually. 


Reset to factory defaults 

The following steps resets the Major to factory 

defaults. 

Attention, all parameters will be reset 

without acknowledgement.

Sample confi gurations Major 4a (5a) 

The following situation shows the easiest way for remote radio control using a Major 4a (5a). 

A local 7-wire line (Audio, squelch, PTT) is required if remote channel select is not necessary. 

For situations not using local lines, the following confi guration for leased lines (PTT certifi ed) is 

necessary.
