TOT(TRANSMISSION
TIMER):
This function can automatically control the time we transmit each time you press [PTT] on the transceiver. This
feature is very useful to avoid overheating excessive power transistors of the transceiver. The transceiver will be
off transmission automatically once the set time.
12.8.
CTCSS/DCS:
In
some
cases
only
want
to
establish
communications
in
a
closed
user
group
at
a
particular
frequency
or
channel,
for
it
will
use
"CTCSS"
or
code
"DCS"
for
reception.
The
"squelch"
opens
only
when
receiving
a
frequency
with
"CTCSS"
or
codes
"DCS"
same
as
the
programmed
in
your
transceiver.
If
codes
of
the
received
signal
differs
from
those
programmed
in
your
transceiver,
the
"squelch"
will
not
open
and
the
received
signal
can
be
heard.
Note:
- The use of "CTCSS" or "DCS" in a communication, does not guarantee complete confidentiality
communication.

ANI
‐
ANI
(Automatic
Number
Identification)
is
also
known
as
PTT
ID
because
an
ID
is
transmitted
when
the
PTT
button
of
the
radio
is
pressed
and/or
released.
This
ID
tells
the
dispatcher
which
field
radio
was
keyed.
Only
could
be
set
by
PC
software.

DTMFST
(DTMF
TONE
OF
TRANSMITTING
CODE
):
First you should set the PTT‐ID as BOT/EOT/BOTH
‐“OFF”—Under transmitting mode, you can’t hear the DTMF tone, while you press the key to transmit
the code or code automatically transmitted.
‐“DT‐ST”—Under transmitting mode, you can hear the DTMF tone, while you press the key to transmit
the code.
‐“ANI‐ST”—under transmitting mode, you can hear the DTMF tone, while the code automatically
transmitted.
‐“DT‐ANI”—under transmitting mode, you can hear the DTMF tone, while you press the key to transmit
the code or the code automatically transmitted.

SC
REV(SCAN
RESUME
METHOD):
This
transceiver
allows
you
to
scan
memory
channels,
all
the
bands
or
part
of
the
bands.
When
the
transceiver
detects
a
communication,
the
scan
will
stop
automatically.
