PA G E 9

your tX3420 will allow you to store up to ten (10) of your
most frequently called selcall numbers in memory .
Each number can be labelled with a 5-letter name for
easy identification .

selcall iDeNtiFicatioN Number

your tX3420 is factory programmed with its own unique
selcall identification number (ident) . this number identifies
your radio from others in your area . your radio’s own selcall
ident will be displayed for a few seconds, directly beneath
the channel display, when you first turn the radio on .

you will need to make your ident known to anyone who
may need to call you using selcall . Whenever your tX3420
hears a selcall signal, it compares the incoming ident with
its own . if the two idents match, the radio knows it is being
called and sounds an alarm to alert you, otherwise the call
is ignored .

Note: Although your radio’s selcall ident is preprogrammed
at the factory, you can arrange to have your retailer change
it if required .

selcall iDeNt Names

When storing selcall idents in memory, the tX3420 allows
you to add a 5 character name to each one, making it easier
to identify whose ident you are recalling from the memory .
in addition, if an incoming selcall matches one of the idents
stored in the memory, the name can be displayed to make it
easier for you to identify the caller .

to add or display names

your tX3420 must be in AlPhA mode .

to switch between

‘alPha’ and ‘Numeric’ mode

briefly press the F (function) key followed by the alPha
key . ‘AlPhA’ or ‘numEr’ will be displayed for 2 seconds
below the channel display to indicate the selected mode .

Quiet moDe (Q)

your tX3420 can be set to monitor signals on a busy
channel but remain quiet unless it receives its own selcall
ident . in this way, you won’t be disturbed unless someone
calls you . When a signal containing your selcall ident is
received, quiEt mode is deactivated and an alarm sounds
to alert you to the call . you can then converse normally on
the channel .

to use Quiet mode

Please refer to the Quiet mode section on page 11 .

Note: quiEt mode overrides the normal squelch system to
ensure that the radio remains quiet even when the channel

is busy . When quiEt is set, you may see the ‘busy’ icon
appear on the display indicating the channel is being used .
however, unless someone transmits your selcall ident,
nothing will be heard in the speaker .

you can activate quiEt mode on individual channels i .e .
some channels can be set to remain quiet while others can
remain open to all incoming signals .

tiP: setting quiEt mode is not mandatory . you can still
use selcall on any channel whether the quiEt mode is set
or not .

selcall memories

your tX3420 is fitted with one call memory and 10 selcall
ident memories . the 10 selcall ident memories are used
to store frequently used selcall idents . the additional call
memory holds the ident you last sent or received . the
memories can be viewed by briefly pressing the call key .
the initial memory displayed is the call memory . rotating
the channel knob will step through the other 10 selcall
storage memories in sequence . selcall memories are
