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 below.

To activate DCS, press [F], [CALL].

• As you press [F], [CALL], the selection cycles as follows:

“OFF” ➞ “TONE” ➞ “CTCSS” ➞ “DCS” ➞ “OFF”.

• “DCS” appears on the upper part of display, indicating that

the DCS function is activated.

When DCS is ON, you will hear calls only when the
selected DCS code is received. To answer the call, press
and hold Mic [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 deactivates the CTCSS/ Tone
functions.
