CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)

CTCSS is available only when the optional TSU-8 unit is

installed {page 54}. CTCSS allows you to choose which

stations will receive your transmissions. Suppose that only

stations “A”, “B”, and “C” are programmed with the same

RX Tone frequency, and this frequency is identical to the TX

Tone frequency. When “A” calls, the squelch on only “B”

and “C” opens. Or, these same stations could be

programmed as follows:

“A”: 91.5 Hz (RX)

“B”: 100.0 Hz (RX) / 91.5 Hz (TX)

“C”: 103.5 Hz (RX) / 91.5 Hz (TX)

In this example, “A” can call either “B” or “C” individually by

selecting 100.0 Hz TX Tone or 103.5 Hz TX Tone.

USING CTCSS

1 Select the desired RX and TX Tone frequencies

(page 23}.

2 Repeatedly press [TONE] until “CT’ appears on the

Display. Each press of [TONE] switches through the

choices shown below.

No Indicator

TONE

(‘T")

CTCSS

("CT")

• The CTCSS indicator does not appear if the CTCSS unit is

not installed.

When you are called;

The squelch of your transceiver opens only when the

selected RX Tone is received.

When you make a call;

Press and hold microphone [PTT].

* The selected TX Tone is superimposed on your

transmitted signal.

Hole: When using DTSS with CTCSS, the squelch opens only If the

correct Tone is received and the received DTSS code matches the code

stored in your transceiver.

m Automatic Tone Frequency ID

This function automatically identifies the incoming Tone

frequency on a received signal.

1 Press [TONE] (1 s) to toggle the function ON or

OFF.

• A Tone frequency display replaces the frequency

display and the 10 kHz decimal begins blinking.

• When a signal is received, the transceiver begins

scanning through all Tone frequencies in order to

identify the Tone frequency that is being received.

When the frequency is identified, an alarm beeps, and

the Display begins blinking.

2 Press any key to cancel the function.

• When OFF is selected for ‘TONE.RX” in Menu B

(page 17}, the Tone frequency selected for ‘TO” in

Menu A is replaced by the Tone frequency

automatically identified in Step 1.

• When any Tone frequency is selected for ‘TONE.RX”

in Menu B (page 17}, this frequency is replaced by the

Tone frequency automatically identified in Step 1. The

Tone frequency selected for TO” in Menu A is not

changed.
