CTCSS/CDCSS Operation
Your scanner is equipped with a Continuous Tone
Controlled Squelch System (CTCSS) and Continuous
Digital Controlled Squelch System (CDCSS) which allow
squelch to open only when the tone you have programmed
with a specific frequency is received along with a
transmission. When using CTCSS or CDCSS, consider the
following:
nYour Scanner Scan Speed becomes slow while
Subaudible Tone function is activated.
nYou cannot enter CTCSS and CDCSS tones in
the AM Air Band.
nIf you have more questions about CTCSS or
CDCSS see What is CTCSS and CDCSS on
page 4.
