q Enter "DTCS-P" in DUP.T set mode.
MENU DUP.T
(Push [MENU
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.

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
](5).)
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.
