CTCSS/DCS/EPCS O
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does CTCSS. The DCS Encoder/Decoder is built into your VX-8R, and operation is very
similar to that just described for CTCSS. Your repeater system may be configured for
DCS. The DCS Squelch may be quite useful in Simplex operation if your friends use
transceivers equipped with this advanced feature.
Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS
and that you select a DCS code.

2. Rotate the DIAL knob until "DCS
this activates the DCS Encoder/Decoder.
3. Press the
mal operation.
4. Press the
key, then press the
"Short-cut" to Set Mode Item 26: DCS CODE
5. Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask the
repeater owner/operator if you don't know DCS Code; if you are working simplex,
just set up the DCS Code to be the same as that used by your friends.
6. When you have made your selection, press the
exit to normal operation.
Remember that the DCS is an
Encode/Decode system, so your
receiver will remain muted until
a matching DCS code is received on an in-
coming transmission. Switch the DCS off
when you're just tuning around the band!
