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:
n Your Scanner Scan Speed becomes slow while
Subaudible Tone function is activated.
n You cannot enter CTCSS and CDCSS tones in
the AM Air Band.
n If you have more questions about CTCSS or
CDCSS see What is CTCSS and CDCSS on
page 4.
