CTCSS-
CTCSS FREQUENCY ID
This function scans through all CTCSS frequencies to
identify the incoming CTCSS frequency on a received
signal. You may find this useful when you cannot recall
the CTCSS frequency that the other persons in your group
are using.
1 Press [TONE] 2 times to activate the CTCSS function.
• The icon appears on the display when the CTCSS
function is ON.
• Each press of [TONE] changes the selection as follows:
Tone ( ) –> CTCSS ( ) –> DCS ( ) –> Off (no
display).
2 Press [F], [T.SEL] (1s).
• The icon blinks and “SCAN” appears on the display.
• Scan starts when a signal is received.
• To reverse the scan direction, turn the Tuning control
clockwise (upward scan) or counterclockwise (downward
scan). You can also press microphone [UP]/ [DWN].
• To quit the scan, press [ESC].
• When a CTCSS frequency is identified, the identified
frequency appears on the display and blinks.
3 Press the Tuning control to program the identified
frequency in place of the currently set CTCSS
frequency.
• The CTCSS function will remain ON. To cancel CTCSS,
press [TONE] until CT no longer appears on the display.
• Press [ESC] if you do not want to program the identified
frequency.
• Rotate the Tuning control while an identified frequency is
blinking, to resume scanning.
