• if a signal appears on the Priority channel - at any time - the
receiver will switch straight to the Priority channel and will stay
there for as long as the channel is busy. during this time you
can transmit on the Priority channel in the usual way. once
there has been no activity for 5 seconds, the radio will resume
scanning the other channels.
• if a signal appears on one of the other channels, scanning will
pause on that channel and will remain there while the channel
is busy, as long as there are no signals on the Priority channel.
during this time the receiver will continue to check the Priority
channel for signals every 2 seconds, resulting in a series of small
'breaks' in the reception of the paused channel. once there has
been no activity on any channel for 5 seconds, the radio will
resume scanning.
• i f your radio pauses on a busy channel and you don't wish to
listen to that conversation, briefly press the SKIP key on the

scanning from the next channel in the sequence.
• if your radio is paused on a busy channel and you wish to
remain there, briefly press the SCAN key. the radio will exit
scan mode and remain on the busy channel.

channel (unless it is the same as the busy channel). to resume
scanning, press the SCAN key again.
• to transmit on the Priority (working) channel At Any timE,
simply press the PTT key while the radio is scanning. the radio
will switch straight to the Priority channel. When you have

uSing two group Scan or
two open Scan moDeS
if you prefer, the tX3340 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.
PA G E 8
your tX3340 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
Press the 'F' key followed by the OS/GS key. 'scan 1' or 'scan 2'
will be displayed to confirm your selection. When enabled, the two
scan modes will be identical in operation.
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
tX3340'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 tX3340 to your retailer
for re-programming.
SElECTIVE CAllINg
your tX3340 has a selective calling system known as selcall that
operates like a telephone. your radio is pre-programmed with its
unique selcall identification number. if this number is called by
another radio, your tX3340 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 tX3340 will allow you to store up to ten (10) of your most
frequently called selcall numbers. Each number can be labelled
with a 5-letter name for easy identification.
Selcall iDentiFication numBer
your tX3340 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 tX3340 hears a selcall
signal, it compares the incoming ident with its own. if the two
