your priority channel, please contact your retailer) .

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 .

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

the radio will resume scanning .

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 .
sElEcTIVE cAllING
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 .
