: Some repeaters may or may not re-transmit a CTCSS tone - some systems just
use CTCSS to control access to the repeater, but don’t pass it along when transmitting.
If the S-Meter indicats, but the VX-7R is not passing audio, repeat steps “1” through “3”
above, but rotate the DIAL so that “SQL” disappears - this will allow you to hear all
traffic on the channel being received.

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-7R, 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
transceivers 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.
1.
Press the [MON/F] key, then press the [8(TONE)] key. This provides a “Short-cut”
to Menu Item (TSQ/DCS/DTMF #1: SQL TYPE).
2.
Press the [MAIN] or [SUB] key until “DCS” appears on the display; this activates
the DCS Encoder/Decoder.
3.
Now rotate the DIAL to select Menu Item (TSQ/DCS/DTMF #3: DCS SET).
4.
Press the [BAND(BND DN)] key to enable the adjustment of the DCS code.
5.
Press the [MAIN] or [SUB] key 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
friend(s).
6.
When you have made your selection, press the [BAND(BND DN)] key, then press
the PTT switch 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!

In operating situations where you don’t know the CTCSS or DCS tone being used by
another station or stations, you can command the radio to listen to the incoming signal
