to scan for active frequencies
and store them into a listening channel
1 . select the required listening channel (41-99) .
the frequency currently stored in that channel will
be displayed .
2 . Enter the Frequency edit mode by pressing and holding
mEnu key until a beep is heard .
3 . Briefly press the scan key . the radio will begin
scanning, using the selected channel step, starting from
the current frequency . the channel number will remain
constant (because the radio is scanning frequencies not
channels) but the frequency will change as the scan
advances through the band .
4 . When a signal is found, scanning will pause on that
frequency . once the signal has disappeared and the
frequency remains clear for 5 seconds, scanning
will resume .
5 . to manually skip over an active frequency and continue
scanning press the call/sKiP button .
6 . When you find a frequency you wish to store, press
and hold the channel knob until a beep is heard .
the frequency will be stored under the selected listening
channel number, but the Frequency Edit menu will
still be active, ready for further seeking . to store the
frequency and exit the menu, press and hold the
mEnu button .
7 . to exit the Frequency Edit menu without saving the
current displayed frequency, briefly press the mEnu key .
the next menu item will be shown (typically the squelch
set menu) . At this stage, press and hold the mEnu
button until a beep is heard to exit .
sEtting sEEK moDE FrEQuEncy limits
When in seek mode, the default frequency band to scan is
the entire receiver tuning bandwidth of 403 mhz-520 mhz .
however, in many cases you may only be interested
in searching for signals within a small section of the
available frequency band . to make searching easier the
tX3420 allows you to set upper and lower frequency limits .
the seek function will then only search within the specified
range, thereby increasing the chance of finding an active
frequency of interest .
there are two seek limit points available, lim-1 and
lim-2 . While in the frequency edit mode, press and hold
the scan key until a beep is heard to store the current
frequency as a limit . to select and jump to the next limit,
press the Vol knob .

to select and display a limit point
While in frequency edit mode, briefly press the Vol knob .
the next frequency limit point will be selected, the display
will briefly show 'lim-1' or 'lim2' and then the frequency
of the limit point will be shown . At this stage the radio is
also tuned to this frequency, and if there is activity on this
frequency, it can be heard in the speaker .
to set or edit a limit point
1 . select the desired limit point to edit as described in the
previous paragraph .
2 . rotate the channel knob until the display shows the
frequency of the desired limit point .
3 . Press and hold the scan key until a beep is heard .
the current frequency is now stored to the current limit
point . the display will briefly show 'lim-1' or 'lim-2',
and then revert to showing the frequency again .
4 . repeat steps 2-3 to update the current limit point with
a new frequency if desired .
to erase a limit point
1 . select the desired limit point to erase as described above .
2 . rotate the channel knob counter clockwise until the
frequency display reads 'oFF' .
3 . Press and hold the scan key until a low beep is heard .
the selected seek limit point is now erased .
using thE FrEQuEncy limits to scan
once the seek mode frequency limits are set, the frequency
band is effectively split into three segments .
tiP: it is easiest to picture the limit points as the first limit
being lower in frequency than the second, but this is not
really necessary . Even if the frequencies are programmed so
that the limit points are reversed, the tX3420 will always
scan inside a selected frequency range, in the upwards
direction . the initial frequency where the seek was started
determines which frequency band will be scanned .
MHz

to start seeking between
the first and second frequency limit
1 . While in Frequency Edit mode, rotate the channel knob
to select a frequency that is between the two frequency
limit points .
2 . start seeking by briefly pressing the scan button .
