Searching for CTCSS Tones
You can use the CTCSS Tone Search Mode to determine if the frequencies in your area are
broadcast with associated tones. You may find frequencies which do not have a tone associated
with them. This may be because CTCSS tones are not being transmitted or because digital
encoded tones, sometimes called DCS, are used and your scanner does not recognize these.

is identified, then your scanner starts
searching where it left off when the
transmission begins again.
If a CTCSS tone is found, the tone begins
flashing in the display.
