Memory Channel) where a signal is detected.  It then
continues or stops scanning according to which Resume
Mode you have selected.

The transceiver remains on a busy frequency (or

SELECTIVE CALL
CTCSS AND DCS
You may sometimes want to hear calls from only specific
persons or groups.  In this case, use 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.

DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS
This transceiver provides you with 10 dedicated DTMF
Memory Channels.  You can store a DTMF number (16
digits max.) in each of these channels to recall later for
speed dialing.
Many repeaters in the U.S.A. and Canada offer a service
called Autopatch.  You can access the public telephone
network via such a repeater by sending DTMF tones.  For
further information, consult your local repeater reference.
