Dcs Operation - Vertex Standard VX-110 Operating Manual

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-110, and operation is very
similar to that just described for CTCSS. Your repeater system may be configured for
DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use trans-
ceivers equipped with this advanced feature.
Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that
you select a tone code.
Press the [ F ] key, then immediately press the [ M/V ( SET )] key to enter the Set mode.

When you have made your selection of the DCS mode, press the PTT key.
Re-enter the Set mode, then rotate the DIAL to select Menu Item #25 ("
Press the [ F ] key to enable modification of the current setting.
Rotate the DIAL to select the desired DCS Code (a three-digit number). Ask the re-
peater 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 friend(s).
When you have made your selection, press the [ F ] key, then press the PTT key to save
the new settings and 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 incoming transmission. Switch the DCS off
when you're just tuning around the band!
