You may sometimes want to hear calls only from specific persons.
The Continuous Tone Coded Squelch System (CTCSS) allows you
to ignore (not hear) unwanted calls from other persons who are
using the same frequency. To do so, select the same CTCSS tone
as selected by the other persons in your group. A CTCSS tone is
subaudible and is selectable from among 42 tone frequencies.
Note: CTCSS does not cause your conversation to be private. It only
relieves you from listening to unwanted conversations.
■ Using CTCSS
Press [F], [1] 2 times to turn the CTCSS function ON.
• Continually press [F], [1] to cycle through the functions as
follows: Tone ON >> CTCSS ON >> DCS ON >> OFF.
• The " " icon appears when the CTCSS function is ON.
Note:
◆ You cannot use the CTCSS and Tone/ DCS functions
simultaneously. Switching the CTCSS function ON after having
activated the Tone/ DCS functions deactivates the Tone/ DCS
functions.
◆ If you select a high CTCSS frequency, receiving audio or noise
that contains the same frequency portions may cause CTCSS
to function incorrectly. To prevent noise from causing this
problem, select an appropriate squelch level.
