reCeiVing signAls
While the TX670 is not receiving signals, it will remain
in the standby mode to conserve battery power.
When a signal is received, the LED indicator on the
upper edge of the radio will light green and the icon
will appear on the display. Adjust the
Volume
control
for a comfortable listening level.
if the incoming signal is encoded with a ctcss
tone that matches the one set in your radio, the LED
indicator will light orange and you will be able to hear
the signal in the speaker.
if the lED indicator lights green and the icon
appears but you cannot hear the signal, it is likely that
your radio has ctcss enabled and the incoming signal
is not using your selected ctcss tone (see ‘mode
settings’ for more details on ctcss settings).
