OTHER FUNCTIONS
Tone/DTCS squelch
q
Set the desired operating frequency on FM or FM-N
mode, CTCSS tone and DTCS code.
w
Push and hold
[TONE]
(7) for 1 sec. several times to acti-
vate the tone or DTCS squelch. (T SQL or DTCS)
•
Subaudible tone encoder “T,” pocket beep (tone squelch)
“
S
T SQL,” tone squelch “T SQL,” DTCS beep “
S
DTCS,”
DTCS squelch “DTCS,” tone squelch reverse “T SQL-R,” DTCS
squelch reverse “DTCS-R” and no tone operation are activated
in order.
•
Rotating
[DIAL]
while pushing
[TONE]
(7) also selects the tone
functions.
e
Operate the transceiver in the normal way.
r
When the received signal includes a matching tone/code,
the squelch opens and the signal can be heard.
•
When the received signal’s tone/code does not match, tone/
DTCS squelch does not open, however, the S-indicator shows
signal strength.
• To open the squelch manually, push and hold
[SQL]
.
