timE, simply press the Ptt key while the radio is
scanning . the radio will switch straight to the Priority
channel . When you have finished your conversation

using tWo grouP scan
or tWo oPEn scan moDEs
if you prefer, the tX3420 can be re-programmed to have
two Group scan modes or two open scan modes instead
of one of each .
For example there may be applications where you have
no need to scan the Priority channel and would prefer to
have two separate open scan modes . Alternatively you may
have applications where you prefer to have two Group scan
modes with different scan groups in each .
your tX3420 can be retailer programmed to convert the
Group scan mode into a second open scan mode and vice
versa . if you would prefer to have two Group scan or two
open scan modes, you should contact your GmE retailer
to arrange for this feature to be enabled (when using two
Group scan modes the Priority channel will be the same
channel for both scan groups) .
When the second open or Group scan mode is enabled,
the resulting two scan modes become scan 1 and scan 2 .
to select the required scan mode
When enabled, the two scan modes will be identical in
operation . to program and operate each, refer to the open
scan/Group scan sections above .
note: Enabling or disabling the second open or Group
scan mode is not a user selectable option . once enabled
by your GmE retailer, the changed scan mode becomes
a permanent part of the tX3420's features and replaces
the standard scan selection . if you find later that you need
the original Group or open scan function re-enabled,
you will need to return your tX3420 to your retailer for
re-programming .
PA G E 8
your tX3420 has a selective calling system known
as selcall that operates like a telephone . your radio is
preprogrammed with its unique selcall identification
number . if this number is called by another radio, your
tX3420 will beep to alert you . if you do not want to hear
any other activity while waiting on a channel, you can select
quiEt mode . this will force the radio to remain quiet to all
incoming signals until your selcall number is called .
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 .
