(3) Press  or  to select CTCSS;

(4) Press the

key to enter the CTCSS code, and scan the CTCSS code in sequence. When a valid CTCSS code is scanned, it stays on the CTCSS code

and the speaker is turned on.

(5) Press the

key to store the scanned CTCSS code and exit the scan to return to the previous menu. In standby mode, the icon will be displayed on

the top line of the screen. Press and hold the PTT key to make a callback.

To search for a DCS code, do the following:

(1) In VFO mode, enter a known frequency, such as 144.525.

(1) Press

key to enter menu>>Scan>>3 Scan Sub-Code.

(2) Press  or  to select DCS;

(3) Press the

key to enter the DCS code scanning, and scan the DCS code in turn. When a valid DCS code is scanned, it stays on the DCS code and the

speaker is turned on.

(4) Press the

key to store the scanned DCS code and exit the scan to return to the previous menu. In standby mode, the icon will be displayed on

the top line of the screen. Press and hold the PTT key to make a callback.

6.1.4 Sub-Code scan memory

In MR mode or VFO mode, the scanned CTCSS/DCS code can be stored as only TX CTCSS/DCS code, RX CTCSS/DCS code only, TX and RX

CTCSS/DCS code to replace the CTCSS/DCS code setting of the current channel or frequency mode of the radio.

To save the settings of CTCSS/DCS code scan, the operation is as follows:

(1) Press

key to enter menu >> SCAN >> 4 Scan Memory.

(2) Press the

key to enter the Scan Memory setting, and press the  or  key to select:

• ALL: The scanned CTCSS/DCS code will be stored as the received and transmitted CTCSS/DCS code of the current channel or frequency mode (at

the same time as the received and transmitted Sub-Code).

• DECODER: The scanned CTCSS/DCS code will be stored as the receiver CTCSS/DCS code of the current channel or frequency mode (only replace its

receiver RX CTC/DC

S).

• ENCODER: The scanned CTCSS/DCS code will be stored as the transmitted CTCSS/DCS code of the current channel or frequency mode (only

replace its transmitted TX CTC/DCS).

(3) Press the

key to save the settings and return to the previous menu;

Note: Only when a valid CTCSS/DCS code is scanned and stopped, press the

key to store the CTCSS/DCS code and replace the

corresponding CTCSS/DCS code of the current channel or frequency.

6.2 DTMF

DTMF is an in-band signaling method using dual sinusoidal signals for any given code. Originally developed for telephony systems, it has proved a very

versatile tool in many other areas.
