OTHER FUNCTIONS
DTCS polarity setting
q
Enter “DTCS-P” in DUP.T set mode.

(5).)
w
Push

(2) or
[

]
(8) to select the desired DTCS polarity
mode.
• BOTH N :
Normal phase is used for both TX and RX.
(Default)
• TN-RR
:
Normal phase is used for TX; Reverse phase
for RX.
• TR-RN
:
Reverse phase is used for TX; Normal phase
for RX.
• BOTH R
:
Reverse phase is used for both TX and RX.
e
Push
[
]
(5) (or
[
´
]
(4)) to return to DUP.T set mode, and
push
[MENU
]
to return to frequency indication.
Tone scan
The transceiver can detect the subaudible tone frequency
and DTCS code in a received signal. By monitoring a signal
that is being transmitted on a repeater input frequency, you
can determine the tone frequency required to access the re-
peater.
q
Set the desired frequency on FM/FM-N mode or memory
channel to be checked for a tone frequency or DTCS
code.
w
Push and hold
[TONE]
(7) for 1 sec. several times to acti-
vate the repeater tone, tone squelch or DTCS squelch. (T,
T SQL or DTCS)
•
Rotating
[DIAL]
while pushing and holding
[TONE]
(7) also se-
lects the tone functions.
e
Push and hold
[T.SCAN]
(9) for 1 sec. to start the tone
scan.
• To change the scanning direction, rotate
[DIAL]
.
r
When the tone frequency or DTCS code is decoded, the
set mode contents are programmed with the frequency or
code.
•
The tone scan pauses for the set period in scan pause timer
(p. 121) when a tone frequency or DTCS code is detected.
•
The decoded tone frequency is used for the repeater tone fre-
quency when the tone squelch is OFF.
•
The decoded tone frequency is used for the tone squelch fre-
quency when the tone squelch is ON.
•
The decoded DTCS code is used for the DTCS squelch code
when the DTCS squelch is ON.
