GME TX3400 - Manual (Page 6)

Selecting a Scan Group.
The current scan group is shown on the display
as OS for Open Scan or GS for Group Scan.
To change the selected scan group:
• Briefly press the OS/GS key.
A beep will be heard and the display will
change to reflect the scan group you have
selected.
Programming Scan Channels.
Your TX3400 is supplied with all 40 UHF CB
channels programmed into the Open Scan
memory. Any channels not required can be
removed as necessary. The Group Scan
memory is empty by default and you will need
to add channels to it before use.
To add or remove channels from either scan
memory:
1. Check that the radio is not already
scanning. If it is, briefly press the SCAN key
to cancel the scan function.
2. Select the required scan group by pressing
the OS/GS key.
3. Select the required channel using the rotary
channel selector switch.
• If ‘M’ is displayed to the upper left of the
channel number, the selected channel is
presently in the scan memory. It can be
removed by holding the SCAN key in for a
few seconds until a low beep is heard. ‘M’
will then disappear indicating the channel is
no longer in memory.
• If ‘M’ is not visible to the upper left of the
channel number, then the selected channel
is not in the memory. To add it, hold the
SCAN key in for a few seconds until a high
beep is heard. ‘M’ will now appear to the
upper left of the channel number.
4. Repeat step 3 to add or remove other
channels in the scan memory.
To Start Scanning:
To scan in the selected scan mode, briefly
press the SCAN key. A high beep will be heard,
‘SCAN’ will appear in the display and the radio
will begin scanning.
NOTE: If there are less than 2 channels
programmed in the scan memory in Open Scan
or one channel in Group Scan when you press
the SCAN key, a long low beep will be heard
and the command will be ignored.
Scanning in the Open Scan Mode.
• If a busy channel is found, scanning will
pause on that channel to allow the signal to
be heard and will remain there for as long as
the channel remains busy. Once the channel
has been clear for 5 seconds, scanning will
resume automatically.
• If your radio pauses on a busy channel and
you don't wish to listen to that conversation,
briefly press the CALL button on top of the
microphone. The radio will skip over that
channel and resume scanning from the next
channel in the sequence.
• To talk while paused on a busy channel,
simply press the Push-To-Talk (PTT) button
on the microphone. The SCAN mode will be
put on hold and the radio will stay on that
channel. You can now converse on that
channel in the usual way. When you have
finished your conversation, briefly press the
CALL button to resume scanning.
• If your radio is paused on a busy channel
and you wish to remain there, briefly press
the SCAN key. The radio will exit the Scan
mode and remain on the busy channel.
• If your radio is scanning and you need to
use your Priority channel (for an urgent call
or an emergency), briefly press the channel
knob. The Scan mode will be cancelled and
the radio will jump straight to the Priority
channel.
NOTE: Your TX3400 will not allow you to
transmit while it is scanning channels in the
Open Scan mode. If the PTT button is pressed
