CTCSS/CDCSS Scan
Before setting CTCSS/CDCSS scanning, set the receiving
frequency to ensure that the signal can be received at the
receiving frequency, and cancel the dual standby function,
and make the radio work in the frequency mode.
1）CTCSS Scan
A.Press the number key to enter the correct frequency.
B.Press【MENU】to enter menu mode.
C.Press【▲】/【▼】to select “Scan CTCSS”, Or enter
the number 28 directly into the menu item.
D.Press【MENU】key.
The CTCSS changes indicate that the machine has
entered the CTCSS scanning status, then CTCSS changes
rapidly according to the standard sequence. When the
radio finds that the CTCSS in the receiving signal is
consistent with one of the standard sets of CTCSS, the
radio stops scanning and receives the speech.
E. Press [BACK] to exit.
2）CDCSS Scan
A.Press the number key to enter the correct frequency.
B. Press【MENU】to enter menu mode.
C. Press【▲】/【▼】to select “Scan DCS”, Or enter the

CTCSS/CDCSS
CTCSS/CDCSS is mainly used to avoid receiving unrelated
calls on the same frequency. If CTCSS/CDCSS is set, only
calls with the same tone signal set in the channel can be
received within the effective communication range. However, if
CTCSS/CDCSS signaling is not set up, all calls on the same
channel in the valid communication range can be heard.
The CTCSS/CDCSS can be set by write software or manually.
You can set the parameters in menu 10, 11, 12 and 13.
