To switch between Simplex and Duplex modes, select a duplex
channel (1 – 8, 41 – 48) then briefly press the DUP button.
When Duplex mode is selected, ‘DUP’ appears on the display on
that channel.
MON Key
To open the Squelch, press and hold the MON key. This will allow
you to check the current channel for activity before transmitting,
particularly if you have CTCSS enabled. When the Squelch is open,
the LED indicator on the upper edge of the radio will light green,
the icon will appear on the display and you will hear static
or hiss if the channel is clear. Do not transmit if you hear any
conversations. Press and hold the MON key again to close
the Squelch.
CTCSS
To activate or deactivate CTCSS, the current channel must have a
CTCSS code selected via the MODE key, (see MODE key settings
for more details).
sCAn/memorY KeY
The SCAN key is a dual function key that controls both Scan and
Memory Functions.
Scanning Function
Channel Scanning allows you to monitor channels that have been
included in the active scan list. The active scan list includes all
channels which display the icon ‘M’ on the LCD.
To enable channel scanning, briefly press the SCAN key. ‘SCAN’
will be displayed and the radio will show rapidly changing channel
numbers as it scans through the channels. While scanning, briefly
press the or keys to select the scan direction.
To exit Scan mode, briefly press the SCAN key again. The TX670 will
return to normal operation and ‘SCAN’ will disappear from the display.
Scanning Features
• If a signal is received, the scan is paused, allowing you
to transmit and receive on that channel. The radio will
automatically resume scanning a few seconds after the last
reception or transmission.
• Press the PTT switch while the unit is scanning to jump to the
home channel (the home channel is the channel the radio was
on at the time scanning was activated). You can then transmit
and receive on that channel. The radio will automatically resume
scanning a few seconds after the last reception or transmission.
• When the unit has stopped on a busy channel, press the or
keys to ‘skip’ over the busy channel and continue scanning.
TIP:
The Scan mode will reduce the overall battery life because
the Standby (battery saver) feature is overridden. You should
avoid scanning if the batteries are running low and you need to
conserve power.
