CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)

You may sometimes want to hear calls only from specic persons. The Continuous Tone Coded Squelch System (CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency. To do so, select the same CTCSS tone as selected by the other persons in your group. A CTCSS tone is subaudible and is selectable from among 42 standard tone frequencies.

Note: CTCSS does not cause your conversation to be private. It only relieves you from listening to unwanted conversations.

USING CTCSS

1 Select your desired band. 2 Press [TONE] 2 times to activate the CTCSS function.

• The icon appears on the display when the CTCSS function is ON.

• Each press of [TONE] changes the selection as follows:

Tone (T) –> CTCSS (CT) –> DCS (DCS) –> Off (no display).

3 Press [F], [TONE].

• The current CTCSS frequency appears on the display and blinks.

4 Rotate the Tuning control to select your desired CTCSS frequency.

• Refer to the table below for the available frequencies.

• To exit the CTCSS frequency selection, press [F] (ESC).

5 Press any key other than the Tuning control and [F] (ESC) to complete the

setting.

6 When you are called: The transceiver squelch opens only when the selected

CTCSS tone is received. When you make a call: Press and hold [PTT], then speak into the microphone.

• To cancel CTCSS, press [TONE] until CT no longer appears on the display.

You can also select a CTCSS frequency by using the microphone:

1 Select your desired band. 2 Press [TONE] 2 times to activate the CTCSS function.

• The icon appears on the display when the CTCSS function is ON.

• Each press of [TONE] changes the selection as follows:

Tone (T) –> CTCSS (CT) –> DCS (DCS) –> Off (no display).

3 Press [F], [TONE].

• The current CTCSS frequency appears on the display and blinks.

4 Press the key programmed as [ENTER].

5 Enter a frequency reference number (01 ~ 42) using the microphone keypad.

• Refer to the table below for frequencies and their reference numbers.

6 Press [ENTER] again to complete the setting.

CTCSS FREQUENCY ID

This function scans through all CTCSS frequencies to identify the incoming CTCSS frequency on a received signal. You may nd this useful when you cannot recall the CTCSS frequency that the other persons in your group are using.

1 Press [TONE] 2 times to activate the CTCSS function.

• The icon appears on the display when the CTCSS function is ON.

• Each press of [TONE] changes the selection as follows:

Tone (T) –> CTCSS (CT) –> DCS (DCS) –> Off (no display).

2 Press [F], [TONE] (1s).

• The icon blinks and “SCAN” appears on the display.

• Scan starts when a signal is received.

• To reverse the scan direction, turn the Tuning control clockwise (upward scan) or counterclockwise (downward scan). You can also press microphone [UP]/ [DWN].

• To quit the scan, press [F] (ESC).

• When a CTCSS frequency is identied, the identied frequency appears on the display and blinks.

3 Press the Tuning control to program the identied frequency in place of the

currently set CTCSS frequency.

• The CTCSS function will remain ON. To cancel CTCSS, press [TONE] until CT no longer appears on the display.

• Press [F] (ESC) if you do not want to program the identied frequency.

• Rotate the Tuning control while an identied frequency is blinking, to resume

scanning.

DIGITAL CODED SQUELCH (DCS)

Digital Code Squelch (DCS) is another application which allows you to ignore (not hear) unwanted calls. It functions the same way as CTCSS. The only differences are the encode/ decode method and the number of selectable codes. For DCS, you can select from 104 different codes.

USING DCS

1 Select your desired band. 2 Press [TONE] 3 times to activate the DCS function.

• The icon appears on the display when the DCS function is ON.

• Each press of [TONE] changes the selection as follows: Tone (T) –> CTCSS (CT) –> DCS (DCS) –> Off (no display).

3 Press [F], [TONE].

• The current DCS code appears on the display and blinks.

4 Rotate the Tuning control to select your desired DCS code.

• Refer to the table below for the available codes.

• To exit the DCS code selection, press [F] (ESC).

5 Press any key other than the Tuning control and [F] (ESC) to complete the

setting.

6 When you are called: The transceiver squelch opens only when the selected

DCS code is received. When you make a call: Press and hold [PTT], then speak into the microphone.

• To cancel DCS, press [TONE] until DCS no longer appears on the display.

You can also select a DCS code by using the microphone:

1 Select your desired band. 2 Press [TONE] 3 times to activate the DCS function.

• The icon appears on the display when the DCS function is ON.

• Each press of [TONE] changes the selection as follows: Tone (T) –> CTCSS (CT) –> DCS (DCS) –> Off (no display).

DUAL TONE MULTI-FREQUENCY (DTMF)

The keys on the microphone keypad function as DTMF keys; the 12 keys found on a push-button telephone plus 4 additional keys (A, B, C, D). This transceiver provides 10 dedicated memory channels. You can store a DTMF number with up to 16 digits, along with a memory name of up to 8 digits in each of the channels to recall later for a quick call.

Some repeaters in the U.S.A. and Canada offer a service called Autopatch. You can access the public telephone network via such a repeater by sending DTMF tones. For further information, consult your local repeater reference.

MANUAL DIALING

Manual Dialing requires only two steps to send DTMF tones.

1 Press and hold the microphone [PTT]. 2 Press the keys in sequence on the keypad to send DTMF tones.

• The corresponding DTMF tones are transmitted.

• If the DTMF Hold function is activated, you need not hold down [PTT] while pressing

keys. After transmitting the rst tone (by pressing [PTT] and the rst key), pressing

additional keys will keep the transceiver in transmit mode for 2 seconds.

• If no DTMF number is stored in the selected channel, the frequency display is restored.

n Selecting a Transmit Speed

Some repeaters may not respond correctly if a DTMF number is transmitted

at fast speed. If this happens, change the DTMF number transmission speed from FAST (default) to SLOW.

1 Enter Menu mode and access Menu 302 (DT.SPD) {page 20}.

2 Set the speed to FAST or SLOW.

n Selecting a Pause Duration

You can change the pause duration stored in DTMF Memory channels; the

default is 500 msec.
