General Operating Instructions
The Major 4 is a microprocessor controlled desktop controller for a 2-way radio system. There are
two main versions, one for 12 Volt DC and one for 230 Volt AC. As all functions are controlled by
a microprocessor, its operation is very simple. The Major 4 is switched on by a power switch on
the rearside of the unit. After switching on, the message <Fun ctron> is shown for one second on
the display, then the display extinguishes and the cursor ashes at the input digit. Now the unit is
ready-to-operate; it is positioned in 5-tone mode.
Before using the Major 4, you have to adjust the input and the output levels of the LF. You can
congure it for 2 or 4-wire connection. On the rearside you have a connector with PTT input, squelch
input, LF input, LF output, emergency output and 12 outputs for channel switching.
Optional:
On an additional connector you have an RS232 output. You can connect a printer or a terminal
for documentation.
Optionaly you can connect the Major 4 on a telephone line using the Telephone Interface. With
this option it is possible to connect the radio manually or automatically to the telephone line or
visa versa. If you have noisy signals you can improve decodeing of 5-tones by the optionally
correlator module.
Calling a Radio Subscriber
At rst, the call number is entered via the keypad. The input is complete when the number is
right-aligned on the display. None of the input positions is ashing any longer. The call is transmitted
automatically or by pressing the call button. See also section 5-Tone Sequence Encoder. If not all call
numbers are allowed, the input can also be restricted (see section Call Code Filter).
Call from Radio Subscriber
An incoming call is indicated by a sounding tone like from a telephone. The loudspeaker is switched
on and the loudspeaker LED ashes. See also section 5-Tone Sequence Decoder.
Call Handling
There are two possibilities to communicate with the radio subscriber:
If you use the handset you hear the radio subscriber through the handset; for speaking you have to
press the PTT button on the handset. When the call is terminated, replace the handset.
It is also possible to speak via the red PTT button. In this case you will speak via the built-in
microphone, and after releasing the PTT button you will hear the radio subscriber through the
loudspeaker. See also section Transmitter Keying. Normally, after call termination the loudspeaker is
switched off by the loudspeaker key. It is also switched off by replacing the handset.
The loudspeaker and the handset volume can be set separately. See also section Loudspeaker.
Major 4

- 6 - Kompetent für Elektroniksysteme
Loudspeaker
The loudspeaker can be switched on by pressing the loudspeaker button. lt is switched off by
pressing the loudspeaker button again. lt is also switched on automatically after call transmission,
after pressing the PTT button, and after call identication. The loudspeaker can automatically be
swjtched oft by replacing the handset. The automatic switch-off is programmed at the second digit of
register 042 (EEPROM 1). The loudspeaker can also be switched off by a timer being
programmable in one-second intervals. That timer is automatically started when the loudspeaker is
switched on, and is post-triggered when the carrier signal is identied. The timer is programmed
at digits 3 to 5 of register 042 (EEPROM 1). If a timer is not required, it can be switched off by
programming '000' seconds. lf the loudspeaker has to be set for permanent operation, 'open
operation' has to be programmed at the first digit of register 042 (EEPROM 1). See section
EEPROM 1 Programming Mode.
Register 042
1. digit 1 = Selective operation
0 = Open operation
2. digit 0 = Loudspeaker off after replacing handset
1 = Loudspeaker remains in 'on' position
3. digit value x 100 sec.
4. digit value x 10 sec. Switch off loudspeaker after 'value' seconds
5. digit value x 1 sec.
In the following example the loudspeaker has to be switched off automatically after two minutes.
Selective operation should be switched:
Register 042 Value
1. digit 1 = Selective operation 1
0 = Open operation
2. digit 0 = Loudspeaker off after replacing the handset
1 = Loudspeaker remains in 'on' position 1
3. digit After N * 1 second 1
4. digit switch off 2
5. digit loudspeaker 0
Volume Setting
The loudspeaker and handset volume can be set separately. The handset volume is set by
potentiometer R610 on the handset. To modify the loudspeaker volume, the volume key has
to be pressed first. The message <VOL> is shown now on the left display, and the current
volume ashes on the right display. A volume level between '0' and '9' can be selected. After
setting the volume the previous display status is restored. The set value is maintained even
after switching off the unit.
Noise Suppression
In case of operation via telephone lines and open loudspeaker cross-talk interferences, dialling
noise, etc. may be audible via the loudspeaker. This can be eliminated by a noise suppressor
switch, if the noise level is not too high. This switch releases the loudspeaker only at normal
speech level. The noise suppression can be switched on at digit 2 of register 040 in EEPROM
1 ('0' = off, '1' = on).

Busy Indicator
The busy indicator is programmed in register 041 (EEPROM 1). For busy indicator control the
carrier input is switched to ground. In case of a two-wire system the busy indicator is controlled by
voice activity. lt is congured as follows:
Register 041 5. digit 0 = audio squelch
1 = Carrier input low = LED on
2 = Carrier input high = LED on
Simplex/Duplex Mode
To avoid a side tone in case of a two-wire connection the Major 4 has to be programmed for simplex
mode. Therefore, the rst digit of register 043 (EEPROM 1) has to be programmed with a '1'. In case
of duplex mode a '0' has to be programmed.
5-Tone Sequence Encoder
Coding
The 5-tone sequence encoder is congured according to the application requirements and as well
for comfortable Operation. Logically, you will permanently code those digits which should not be
entered via the keypad. The permanently coded tones can be placed at any position of the tone
sequence. For example, it is possible to permanently code positions 1, 3, and 5. In this case
only position 2 and 4 are entered via the keypad. The positions to be freely entered are always
displayed right aligned. If two subsequent tones are identical, the repeat tone is automatically
used at the correct position. The 5-tone sequence encoder is coded in register 001 (EEPROM
1). See section EEPROM 1 Programming Mode. If not all digits are permitted, the input can also
be restricted (see section Call Code lter).
Call Start
The call is started either by pressing the call button or automatically after complete input. The call
can be repeated in both cases by pressing die call button. If it has to be started automatically,
the 4. digit of register 040 (EEPROM 1) has to be programmed as a '1'. See section EEPROM
1 Programming Mode.
Call Code Filter
Via the call code lter you can block special digits at any position of the tone sequence. The call code
lter is programmed in the EPROM starting with address 7B80H. For any tone of the tone sequence
16 bytes are reserved, where all permitted tones are listed ('00' H .. '0F' Hex). If one of these tones
shall be blocked, the corresponding position has to be programmed with 'FF' Hex. If no suitable
programming unit is available, FunkTronic can supply you with the modied EPROM.
Permitted tones for 1. position - start with address 7B80 Hex
Permitted tones for 2. position - start with adoress 7B90 Hex
Permitted tones for 3. position - start with address 7BA0 Hex
Pennitted tones for 4. position - start with address 7BB0 Hex
Permitted tones for 5. position - start with address 7BC0 Hex

- 8 - Kompetent für Elektroniksysteme
Short Call Numbers
The Major 4 is provided with 10 programmable short call numbers. By pressing the (Z) key and
the following input of a digit between 0 and 9, a precoded call is transmitted. These short call
numbers are coded in registers 000 to 009 (EEPROM 2) and may be changed at any time without
password input. See section EEPROM 2 Programming Mode.
Identication
The identication is coded in register 003 (EEPROM 1). See section EEPROM 1 Programming
Mode. If no identication number is required, please code the rst digit with an 'F'. Usually, the
identication is coded exactly as Decoder 1. The identication is transmitted automatically after
every call or short call. These two sequences are separated by a pause of one tone length.
The pause can also be replaced by a sixth tone. See section 6-Tone Sequence. In this case a
tone sequence of 11 tones is transmitted.
Group Call
In order to be able to use the 5-tone sequence call system without any restrictions, tone 'A' should
be used as group calling tone. Tone 'A' is entered by the (#) key. The group calling tone may be
placed at any position. The call starts by pressing the call button or automatically, depending on
the conguration. See section Call Start.
Conference Call
The conference call is transmitted by pressing the conference call button. The call duration is
programmed at digit 1 of register 048 (EEPROM 1). The programmed value N refers to the time
of N * 200 ms. But, if '0' is set at this digit, the tone will be transmitted as long as the button is
pressed. The tone frequency is programmed at digits 3 to 5 of register 048. The tone generator
can be programmed for frequencies from 601 Hz up to 3400 Hz or higher. The value to be
programmed is calculated using die following formula:
8 000 000
x = ---------------- - 1
52 * f (Hz)
In the following example a conference call is programmed with a frequency of 1000 Hz. The
call duration should be one second:
8 000 000
x = ---------------- - 1 = 152.846 Value = 153
52 * 1000
Therefore, register 048 (EEPROM 1) has to be programmed with '5-153'. See section EEPROM
1 Programming Mode.

5-Tone Sequence Parameters
Transmitter Pre-Running Time
The pre-running timer is preceding every call. lt consists of a fixed value of 100 ms and a
variable value which can be programmed in 10 ms intervals at digits 3 to 5 of register 046
(EEPROM 1). See section EEPROM 1 Programming Mode. The variable value can be dened
freely between '000' and '255'.
Example 1: ...............................................................................................................................................
The variable value is dened as '010'.
The xed pre-running time value is now 100 ms plus a variable value of 100 ms. Therefore,
the total value is 200 ms.
Example 2: ...............................................................................................................................................
The variable value is dened as '255'.
The xed pre-running time value is now 100 ms plus a variable value of 2550 ms. Therefore, the
total value is 2650 ms or 2.65 seconds.
Tone Length
The length of the rst tone is dened at digits 3 to 5 of register 045 (EEPROM 1). The length of the
other tones can be adjusted at digits 3 to 5 of register 044 (EEPROM 1). See section EEPROM 1
Programming Mode. The value can be switched in 10 ms intervals from '003' up to '255'. In case
of ZVEI 1 and ZVEI 2 the tone length is usually 70 ms, and in case of CCIR it is 100 ms. The tone
length of the rst tone can also deviate from the other tones. For example: Tone length of 1. tone =
1500 ms and 2. to 5. tone = 70 ms. The programmed tone lengths are adhered exactly by the 5-tone
encoder. In case of tone identication a tolerance is added to the programmed values. This ensures
that even inexact 5-tone telegrams are evaluated correctly.
6-Tone Sequence
For special applications it may be necessary to add a sixth tone to the 5-tone sequence. For
every short call <Short Call Button> as well as for normal call <Call Button> the sixth tone can be
programmed separately . The sixth tone for normal call is programmed at digit 3 of register 041
(EEPROM 1). The sixth tone for short calls is programmed in registers 014 and 015 (EEPROM 1). If
the sixth tone is not used, an 'F' has to be programmed at the corresponding address.
Register 014 Register 015
1. digit short call 0 1. digit short call 5
2. digit short call 1 2. digit short call 6
3. digit short call 2 3. digit short call 7
4. digit short call 3 4. digit short call 8
5. digit short call 4 5. digit short call 9
Different Tone Systems
The Major 4 can be congured for various tone systems without any hardware modication. The
tone system is selected at the rst digit of register 046 in EEPROM 1 (see the following table). See
section EEPROM 1 Programming Mode. When a tone system is selected, the tone length is not

- 10 - Kompetent für Elektroniksysteme
automatically adjusted. Therefore, if a change is made from ZVEI 1 to CCIR, the tone length has to
be redened as well. See section Tone Length.
Register 046 1. digit 0 = ZVEI 1
1 = CCIR
2 = ZVEI 2

Transmitter Keying
The transmitter can be keyed by the PTT button on the handset or by the red PTT button on the
keypad. The difference between these PTT buttons is the function of the microphones. The PTT
button on the handset switches on the microphone in the handset, and the PTT button on the keypad
switches on the microphone mounted in the housing of the unit. The transmitter is keyed as long
as the PTT button is pressed, except if the TX time out is exceeded. See also seotion TX Time Out
Timer. In the multi-wire Version the transmitter is controlled by optocoupler 1 and, at the same time,
by an open collector output. In the DC Version it is controlled by optocoupler 2, and in AC version by
a keying tone. During call transmission the transmitter is keyed automatically.
TX Time-Out Timer
The TX time-out timer is programmed in one-second intervals at digits 3 to 5 of register 047
(EEPROM 1). Values of '000' up to '255' are permitted. If the programmed value is '000', the TX
time-out timer is out of operation.
PTT Button Blocking
The PTT button blocking is programmed at the fth digit of register 040 (EEPROM 1) as follows:
0 = PTT button blocking is switched off
1 = PTT button is blocked in case of sensed carrier

m4_eng(11.03.02)

2 = Transmitter keying is possible only after call transmission or call evaluation. The PTT button
release is reset by replacing the handset or by switching off the loudspeaker.
Transmitter Rodger Beep
The pressing of the PTT button may be signalled by transmission of a tone or the identication.
The signal can be transmitted when pressing the PTT button, when releasing the PTT button,
or when pressing and when releasing the PTT button. The function is programmed at digit 5 of
register 033 (EEPROM 1) as follows:
0 = No Signal (default setting)
1 = Tone when pressing the PTT button
2 = Tone when releasing the PTT button
3 = Tone when pressing and when releasing the PTT button
4 = Identication when pressing the PTT button
5 = Identication when releasing the PTT button
6 = Identication when pressing and when releasing the PTT button
Transmitter Keying Tone
The keying tone is programmed at digits 2 to 5 of register 043 (EEPROM 1). If no keying tone
is required the digits have to be programmed with '0000'. The keying tone generator can be
programmed for frequencies of 15,4 Hz up to 3400 Hz or higher. The value to be programmed
is calculated using the following formula:
8 000 000
x = -------------- - 1
52 * f (Hz)
In the following example a keying tone with a frequency of 3300 Hz is programmed:
8 000 000
x = -------------- - 1 = 45,62 Value = 46
52 * 3300
The digits 2 to 5 of register 043 have to be programmed with '0046'.
5-Tone Sequence Decoder
Decoder 1
The Decoder 1 is coded in register 000 (EEPROM 1). See section EEPROM 1 Programming Mode.
Every 5-tone sequence is compared with the decoder 1 coding and, in case of digits being coded
with 'F', every tone of the tone system will be accepted. If the 5-tone sequence has been identied
as correct, the loudspeaker and the handset are switched on, the loudspeaker lamp ashes, and
if you are not operating with double sequences, the acknowledgement is transmitted. After that,
the bell tone is activated. If you operate with double sequences, the acknowledgement delay is at
most one second. See also identication Memory. Any further tone sequence check, for example by
decoder 2 or the conference call decoder, is not performed.

- 12 - Kompetent für Elektroniksysteme
Acknowledgement
The automatic acknowledgement after a selective call can operate in different ways. The
acknowledgement mode is programmed at digit 4 of register 033 (EEPROM 1) as follows:
0 = no acknowledgement
1 = acknowledgement with a single tone of 600 Hz, 300 ms
2 = acknowledgement with a tone sequence from register 002
3 = acknowledgement with the identifcation stored last.
Decoder 2
The decoder 2 is coded in register 007 (EEPROM 1). See section EEPROM 1 Programming
Mode. Every 5-tone sequence which has not been identied as correct in decoder 1, is compared
with decoder 2 coding and, in case of digits being programmed with 'F', every tone of the tone
system will be accepted. If the 5-tone sequence bas been identied as correct, the loudspeaker
and the handset are switched on, the loudspeaker lamp flashes, and then the bell tone is
activated. Any further tone sequence check, e.g. by a group call decoder, will not be performed.
An acknowledgement is not transmitted.
Bell Tone
The bell tone volume is programmed at the rst digit of register 040 (EEPROM 1). The setting '1' ...
'9' corresponds to the volume ('1' = lowest level, '9' = highest level). If no bell tone is desired, a '0' has
to be programmed at this digit. See also section EEPROM 1 Programming Mode.
Alarm Switching Output
After successful evaluation the bell tone is generated and the alarm contact is switched for
n*1 seconds. The alarm contact time is programmed in one-second intervals in register 020
(EEPROM 1) as follows:
1. digit Alarm contact time for emergency call
2. digit Alarm contact time for normal call (Decoder 1)
3. digit Alarm contact time for normal call (Decoder 2)
4. digit Alarm contact time for group call
5. digit Alarm contact time for conference call
Group Call Decoder 0
The group call decoder 0 is coded in register 005 (EEPROM 1). If this decoder is not required,
please code an 'F' (blank) at the rst digit of the tone sequence. The group call decoder is usually
coded with the same tones as decoder 1. The read-in tone sequence is compared with the coded
tone sequence whereby tone '0' is also accepted. In case of successful decoding the loudspeaker
and the handset are switched on, the loudspeaker lamp ashes, and the bell tone is started. An
acknowledgement is not transmitted.
Group Call Decoder A
The group call decoder A is coded in register 006 (EEPROM 1). If this decoder is not required,
please code an 'F' (blank) at the rst digit of the tone Sequence. The group call decoder is normally
coded with the Same tones as decoder 1. The read-in tone sequence is compared with the coded

m4_eng(11.03.02)
- 13 -
Kompetent für Elektroniksysteme
tone Sequence whereby tone 'A' is also accepted. In case of successful decoding the loudspeaker
and the handset are switched on, the loudspeaker lamp ashes, and the bell tone is started. An
acknowledgement is not transmitted.
Emergency Call Decoder
The emergency call decoder is coded in register 004 (EEPROM 1). If this decoder is not required,
please code an 'F' at the rst digit of the tone sequence. The read in 5-tone sequence is compared
with the emergency coding. From the second up to the fth digit those positions being coded with
'F' will accept all tones of the tone system. In case of successful decoding the loudspeaker and
the handset are switched on, the loudspeaker lamp ashes, and a time window with a duration of
three seconds is opened. The rst tone sequence to be received within the time window closes the
time window, and is then stored as emergency call, and ashes on the right display. As long as an
emergency call is indicated on the display, the keypad is blocked with exception of the PTT button and
the 'F1' key. The emergency call number can be deleted only with the 'F1' key.
Conference Call Decoder
The conference call decoder detects a tone of at least one second duration. After detection the
loudspeaker and the handset are switched on, the loudspeaker lamp ashes, and the bell tone is
activated. No acknowledgement is transmitted. The conference call tone frequency is coded at digit
2 of register 046 (EEPROM 1) with the corresponding digit of the tone system ('0' ... 'E') . If this
decoder is not required, please code an 'F' at that digit.
ID-Code Memory
Function
The ID-code memory can be congured so that it is optimally adapted to current use. Up to 16
ID-codes can be stored. If all memory positions are engaged, the memory is updated by deleting the
oldest ID-code. The stored ID-codes can be scrolled through by pressing the (M) key in such way
that the ID-code stored last is displayed by the rst key pressing. The currently displayed ID-code
can be deleted from the memory by pressing the (*) key. If the "FIFO" function is switched on, always
the oldest number is shown on the display by pressing the (M) key, and only after deleting this
ID-code the next ID-code follows. The "FIFO" function is programmed at the rst digit of register 033
in EEPROM 1 ('0' = off, '1' = on). The ID-code memory can be used for single or double sequences.
In case of double sequences the rst or the second tone sequence is stored according to the
"ID-Mode" switch. The "ID-Mode" is programmed at digit 3 of register 033 in EEPROM 1 ('0' = 2nd
tone sequence, '1' = 1st tone sequence). The storing of an ID-code can be signalled by a beep tone
which can be programmed at digit 2 of register 033 in EEPROM 1 ('0' = off, '1' = on). The ID-code
memory can also be used as call-back memory. In order to avoid acknowledgement sequences to
get into the memory, the ID-code memory can be blocked for n * 100 ms after every call transmission.
The blocking time is programmed at digit 2 of register 041 (EEPROM 1).
Monitor
If every ID-code has to be stored, digit 3 of register 021 (EEPROM 1) has to be programmed with
a '1'. Now every ID-code is compared with the key tones and, if the test is positive, it is transferred
to the ID-code memory. But if the system is operating with double sequences, the monitor switch
must remain in "off" position ('0').

- 14 - Kompetent für Elektroniksysteme
Double Sequences
If the system has to operate with double sequences, digit 1 of register 021 (EEPROM 1) has to
be programmed with a '1'. Now after every evaluation of decoder 1, a time window of 1 second
is opened. The rst ID-code, within the time window, which ts the key tones, closes the time
window. The rst or the second ID-code can be transferred to the ID-code memory (according to the
"ID-Mode" switch). Therefore, the acknowledgement transmission is delayed.
Key Tones
The key tones are coded in register 008 (EEPROM 1). The coding of these tones selects the
ID-codes which are stored, and determines the digits to be displayed. Those digits where every tone
is allowed and which are displayed later on, have to be coded with 'F'.
Memory Updating
Before an ID-code is accepted by the ID-code memory, the software checks if the same ID-code
has already been stored in the memory. If the ID-code has already been stored and if the updating
has not been activated, the ID-code is rejected. If the updating is switched on, the ID-code at
the old position is deleted in order to be stored again at the rst position. Therefore, the ID-code
memory is always arranged in chronological order. The memory updating is programmed at digit 5
of register 021 in EEPROM 1 ('0' = off, '1' = on).
Display
The ID-code can be shown on the left as well as on the right display. In case of up to 3-digit
ID-codes the left display should be chosen. The ID-code is always displayed right aligned. If the
ID-code display is requested on the left display, digit 4 of register 021 (EEPROM 1) has to be
programmed with a '1'. If the ID-code shall be shown on the right display, please code a '0'. If an
ID-code is shown on the right display, it can be transmitted via the call button. If the ID-codes
shall be shown on the display automatically after storage, digit 2 of register 021 (EEPROM 1)
has to be programmed with a '1'.
Example:
The following example shows the conguration of an ID-code memory which stores and displays
automatically every ID-code beginning with 1 2. The ID-code memory should be "updated":
Register 008 1. digit 1
2. digit 2
3. digit F
4. digit F
5. digit F
Register 021 1. digit 0
2. digit 1
3. digit 1
4. digit 1
5. digit 1

Setup Mode
Setup Menu
The setup menu is selected by pressing the (F1) key and the (F4) key simultaneously for one second.
Now the message <SET> is shown on the left display and the cursor ashes at the input digit of the
right display. Now it is possible to call the different programs by entering a two digit number (see the
following table). The input is terminated by pressing the (F4) key.
00 = Reset Program
01 = EEPROM 1 programming mode
02 = EEPROM 2 programming mode
03 = Time setting of built in real time clock
04 = Printout of EEPROM registers EEPROM 1
05 = Printout of EEPROM registers EEPROM 2
06 = Software Version display
50 = Service mode processor board
51 = Service mode telephone interface
EEPROM 1 Programming Mode
After selecting the EEPROM 1 in the setup menu, the left display shows the message <Pas>, and
the cursor ashes at the input digit of the right display. Now you have to enter your 5 digit password.
Units leave the factory without password, so that you can immediately start with the programming.
In this case or after you have entered your password, the left display shows the message <Adr>,
and the cursor ashes at the input digit of the right display.
Now the register address to be newly coded has to be entered (see the following table). If, instead
of a valid address, '222' is entered, all registers are programmed with default values. Immediately
after complete input the left display shows the message <Cod>, and the actual coding is shown
on the right display. Now that coding can be overwritten with new values. If the coding shall not be
modied, you can skip the coding by pressing the (F3) key and select a new address. Generally,
in setup mode you conrm the last input by pressing the (F4) key, and by pressing the (F3) key
you go to the next step of the program.
All values from 0 ... 9 and A ... F
can be used for coding. Value F
is shown on the display as '-'.
After complete coding the EEPROM is programmed by pressing the (F4) key. Now the Major
4 shows the word <donE> on the right display for half a second. Then the left display shows
the message <Adr>, and the cursor ashes at the input digit of the right display. Now the next
address can be entered.
If no further coding are requested, you have to quit the programming mode by pressing the (F3)
key. Now the Major 4 is executing a warm start; during this warm start all registers are read in
and the programming mode is terminated.
