Squelch type
Description
OFF
Deactivates the CTCSS and DCS functions. Returns to the normal
squelch operation in the Analog FM mode.
TN
Activates the CTCSS tone for Analog FM Transmissions. Receives
with normal squelch operation.
TSQ
Activates the CTCSS tone squelch function on Analog FM receive.
RTN
Activates the reverse tone function. Used to monitor communications based
on the squelch control system. When a signal contains the designated tone,
the squelch is not opened, and when the tone signal disappears, the squelch
opens, and communication starts.
DCS
Activates the Digital Code Squelch (DCS) function. The DCS code
may be selected from 104 codes (from 023 to 754).
PR
Activates the no-communication squelch function for radios. The no-
communication signal tone frequencies may be specified within the
range of 300 Hz to 3000 Hz in steps of 100 Hz.
PAG
Activates a new two-tone CTCSS pager function.
When
communicating with transceivers among friends, specify personal
codes (each code is composed of two tones) so that only specific
stations are called.
DC*
Transmits the signal containing the DCS CODE. Receives as a
normal squelch operation.
T-D*
Sends a tone signal when transmitting, and receives only signals with
a matching DCS code.
D-T*
Sends a DCS CODE when transmitting and receives only signals that
contain a matching tone signal when receiving.

cess “ON”, “DC”, “T-D” and “D-T” setting values are activated.
• The squelch type may be set for each frequency band (BAND).
• The CTCSS and DCS squelch settings are also active during scanning. If scanning is
performed with the CTCSS and DCS squelch function activated, scanning stops only when
a signal containing the specified CTCSS tone or DCS code is received.
• Pressing the program key on the microphone to which the “SQL OFF” function is assigned,
allows all signals that do not contain a tone or DCS code, and signals with different tones,
DCS codes, digital mode signals to all be heard.
