Memory location 11

 holds the Selcall Ident for the Pager 

function . See the ‘Page Mode’ section for more details on this 
feature . When in ALPHA mode, this memory displays ‘PAGER’ . 

Memory location 12

 holds the last-sent or received 

Selcall Ident . Whenever you send or receive a Selcall, the 
Ident is automatically stored in this location allowing you 
to easily recall it and resend it . When in ALPHA mode, this 
memory displays ‘LAST’ .

Memory location 13

 contains the radio’s own Selcall 

Ident . If you need to give your Selcall Ident to someone but 
can’t remember it, you can recall it from this location . When 
in ALPHA mode, this memory displays ‘RADIO’ . 

The memories can be viewed by briefly pressing the 

CALL 

button on the microphone, then rotating the 
Channel switch . 

ENTERING, STORING AND SENDING 

SELCALLS

Use the following procedure to enter and send a Selcall .

1 .   Press the 

CALL

 button on the microphone . ‘CALL TO’ is 

displayed, along with a memory location on the left and 
an associated 5 digit Selcall Ident on the lower right .

2 . Enter the required Selcall ident as follows:

    (a)   Briefly press the 

Channel

 knob . The right-hand digit 

of the Selcall Ident will flash .

    (b)   Rotate the 

Channel 

knob to select the required 

number in the flashing digit position .

    (c)   Briefly press the 

Channel 

knob again to select the 

next digit position .

    (d)   Repeat steps (b) and (c) to enter all 5 digits  

as required .

3 . Now press and hold the 

CALL 

button to send the Ident .

CALL ACKNOWLEDGE

If your Selcall transmission is successful, the radio you called 
should respond with a 'call acknowledge' signal - usually 
two quick beeps . This will confirm to you that the radio you 
called is now alerting its user to your signal .

STORING SELCALL IDENTS

Your TX4400 is fitted with 10 user programmable Selcall 
Ident memories, allowing you to store up to 10 frequently 
used Selcall Idents . The memories are accessed by pressing 
the 

CALL

 button on the microphone then rotating the 

Channel switch . 

Note:

 Memory locations 1 - 4 are ‘Fast Dial’ memories . 

Once programmed they can be quickly recalled using the 
front panel keys . If you wish to make use of  this feature, 
you should program your four most frequently used Selcall 
idents into the first four memory locations . For details on 
using these ‘Fast Dial’ keys, see section below on

 

‘Recalling Fast Dial Memories’ .
