SELECTIVE CALL
CTCSS AND DCS
You may sometimes want to hear calls from only
specific persons or groups. In this case, use the
Selective Call. This transceiver is equipped with
CTCSS (Continuous Tone Coded Squelch System) and
DCS (Digital Coded Squelch). These Selective Calls
allow you to ignore (not hear) unwanted calls from other
persons who are using the same frequency. The
transceiver unmutes only when it receives a signal
having the same CTCSS tone or DCS code.
Note: CTCSS and DCS do not cause your conversation to be
private or scrambled. It only relieves you from listening to unwanted
conversations.
CTCSS
A CTCSS tone is a sub-audible tone and is selectable
from among the 42 tone frequencies listed in the table
on the page 71. The list includes 37 EIA standard tones
and 5 non-standard tones.
Using CTCSS
