USING QUIET CODES

This radio uses quiet (CTCSS) codes to
screen out unwanted conversations, even if
someone is transmitting nearby on the
same channel. When a quiet code is set,
the radio sends it every time
pressed and only responds to signals that
have the same code. Radios you plan to
use together must be set to the same code.
This radio has these quiet (CTCSS) codes.
