PERATION
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system that generally provides more immunity from false paging than does
CTCSS. The DCS Encoder/Decoder is built into your FTM-10R, 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.
Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and
that you select a DCS Code.
1. Press and hold the [VOL/SEL] key for one second to activate the Menu mode.
2. Rotate the DIAL knob to select Menu Item “F40 SQL TYPE”.
3. Press the
key to enable selection of this Menu Item.
4. Rotate the DIAL knob so that “DCS” appears on the dis-
play. This means that the DCS Encoder/Decoder is active,
which mutes your FTM-10R’s receiver until it receives a
call from another radio sending out a matching DCS tone.
5. When you have made your selection of the DCS mode, press
the key momentarily, then rotate the DIAL knob two
clicks counter-clockwise to select Menu Item “F36 SQL
DCS
”. This Menu selection allows setting of the DCS code
to be used.
6. Press the key to enable adjustment of the DCS code.
7. Rotate the DIAL knob until the display indicates the DCS
code (three-digits number) you need to be using.
8. Press the [VOL/SEL] key to save the new setting and exit to normal operation.
Note: Remember that 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!
