DCS
DCS is similar to CTCSS. However, instead of using an
analog audio tone, it uses a continuous sub-audible
digital waveform that represents a 3-digit octal number.
You can select a DCS code from among the 104 DCS
codes listed in the table on the next page.
Using DCS
1 Press [MENU] and turn the Tuning control to select
Menu No. 2 (T.CT.DCS).
2 Press [MENU] and turn the Tuning control to select
“DCS”.
• As you turn the Tuning control, the selection cycles as
follows: “OFF” ➞ “TONE” ➞ “CTCSS” ➞ “DCS” ➞ “OFF”.
3 Press [MENU].
• “DCS” appears on the display, indicating that the DCS
function is activated.
4 Press any key other than [MENU], [MONI/SQL], and
[LAMP] to exit the Menu Mode.
When DCS is ON, you will hear calls only when the
selected DCS code is received. To answer the call, press
and hold [PTT], then speak into the microphone.
Note: You cannot use the DCS function and CTCSS/ Tone functions
simultaneously. Switching the DCS function ON after having
activated the CTCSS/ Tone functions deactivate the CTCSS/ Tone
functions.
