Vertex Standard FTM-10R manual DCS Operation

DCS OPERATION

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!
