6.1.4 Sub-Code scan storage

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/DCS).

• 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.

In two-way radio systems, DTMF is most commonly used for automation systems and remote control. A common example would be in amateur radio

repeaters where some repeaters are activated by sending out a DTMF sequence (usually a simple single-digit sequence).

The radios has a full implementation of DTMF, including the A, B, C and D codes. The numerical keys, as well as the and keys correspond to the

matching DTMF codes. The A, B, C and D codes are located in the ,  ,  and keys respectively.
