CTCSS FREQUENCY SCAN
This function scans through all CTCSS frequencies to identify the incoming
CTCSS frequency on a received signal. You can use this function to find which
CTCSS frequency is used by your group.
1 Press
[TONE] 2 times to turn the CTCSS function ON.
• Each time you press [TONE], the selection changes as follows:
Tone
( ) ➡ CTCSS ( ) ➡ DCS ( ) ➡ Cross Tone ( ) ➡ Off (no display).
• The “ ” icon appears when the CTCSS function is ON.
2 Press [T.SEL] (1s) to run the CTCSS Frequency scan.
• Scan starts and “CT.SCAN” appears on the display.
• When the CTCSS frequency is identified, a beep sounds and the identified
frequency blinks.
3 Press [T.SEL] to program the identified frequency in place of the current tone
frequency.
• If you do not want to program the identified frequency, press any key other than
[MONI], [LAMP], or [T.SEL].
DCS
Digital Coded Squelch (DCS) is another application which allows you to ignore
(not hear) unwanted calls. It functions the same way as CTCSS. The only
differences are the encode/ decode method and the number of selectable codes.
For DCS, you can select from 104 different codes.

listening to unwanted conversations.
