Selecting a Ctcss Frequency | Kenwood TH-K2E, TH-KAE, TH-K4AT

•As you turn the Tuning control, the selection cycles as follows: “OFF” ➞ “TONE” ➞ “CTCSS” ➞ “DCS” ➞ “OFF”.

3Press [MENU].

•“CT” appears on the upper part of display, indicating that the CTCSS function is activated.

4Press any key other than [MENU], [MONI/SQL], and [LAMP] to exit Menu Mode.

When CTCSS is ON, you will hear calls only when the selected CTCSS tone is received. To answer the call, press and hold [PTT], 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 18}.

◆While transmitting the 1750 Hz tone by pressing [CALL] {page 35}, the transceiver does not transmit the CTCSS tone.
