SELECTIVE CALL

CTCSS and DCS

You may sometimes want to hear calls from only specific persons or groups. In this case, use the selective call function. This transceiver is equipped with CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch). These selective calls allow you to ignore (not hear) unwanted calls from other persons who are using the same frequency. The transceiver unmutes only when it receives the signal having the same CTCSS tone or DCS code.

CTCSS

A CTCSS tone is a sub-audible tone and is selectable from among the 42 tone frequencies listed in the table on the following page. The list includes 37 EIA standard tones and 5 non-standard tones. You can select one of the tones to use as a CTCSS tone.

USING CTCSS

Press [TONE] until “CT” appears.

•Each time you press [TONE], the icon cycles as

follows: “” (TONE) ➞ “CT” (CTCSS) ➞ “DCS” (DCS) ➞ “ ” (OFF) ➞ “” (TONE).

CTCSS frequency: 88.5 Hz

Note:

CTCSS frequency: 88.5 Hz

CTCSS frequency: 100.0 Hz

CTCSS/ DCS:

OFF

When the CTCSS function is ON, you will hear calls only when the selected CTCSS tone is received. To answer the call, press and hold the PTT switch, then speak into the microphone.

Note:

◆ You cannot use the CTCSS and Tone/ DCS functions

simultaneously. Switching the CTCSS function ON after having

activated the Tone/ DCS functions deactivates the Tone/ DCS

functions.

◆ If you select a high CTCSS frequency, receiving audio or noise

that contains the same frequency portions may cause CTCSS to

function incorrectly. To prevent noise from causing this problem,

select an appropriate squelch level {page 6}.

◆ While transmitting the 1750 Hz tone by pressing [CALL]

◆CTCSS and DCS do not cause your conversation to be private or scrambled. It only relieves you from listening to unwanted conversations.

◆CTCSS and DCS function in only FM mode.

{page 13} , the transceiver does not transmit the CTCSS tone.

SELECTING A CTCSS FREQUENCY

1While in CTCSS mode {above}, press [F], [TONE].

• The current CTCSS frequency appears.

2Turn the Tuning control or press []/ [] to select your desired CTCSS frequency.

•The selectable CTCSS frequencies are the same as those for the Tone frequency. Refer to the table on the following page for the available CTCSS frequencies.

3Press [] or [MNU] to store the new setting. Otherwise, press [] or [PTT] to cancel.
