Vertex Standard FTM-10R manual Storing the Ctcss Tone Pairs for Epcs Operation

EPCS(ENHANCED PAGING & CODE SQUELCH) OPERATION

The FTM-10Rincludes an Enhanced CTCSS tone encoder/decoder and a dedicated micro- processor providing paging and selective calling features. This allows you to place a call to a specific station (Paging), and to receive calls of your choice directed only to you (Code Squelch).

The paging and code squelch systems use two pairs of (alternately switched) CTCSS tones, which are stored in the pager memories. Basically, your receiver remains silent until it receives the CTCSS tone pair that matches those stored in the Receiving Pager Memory. The squelch then opens so the caller is heard, and the paging ringer immediately sounds, if activated. When you close the PTT key to transmit, the CTCSS tone pair that is stored in the Transmitting Pager Memory will be transmitted automatically.

On the paged radio, the squelch will close automatically after the incoming page ends.

STORING THE CTCSS TONE PAIRS FOR EPCS OPERATION

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 “F21 PAGER”.
3.	Press the	key to enable selection of this Menu Item.
4.	Press and hold the			key for one second to display the
	current Receiving CTCSS Tone Pair.
5.	Rotate the DIAL knob to set the CTCSS Tone number that
	corresponds to the first tone of the Receiving CTCSS Tone
	Pair.		key, then rotate the DIAL knob to set the
6.	Press the
	CTCSS Tone number that corresponds to the second tone
	of the Receiving CTCSS Tone Pair.
7.	Repeat step 6 for setting the Transmitting CTCSS Tone Pair.
8.	If you make a mistake, press the				key to move the cur-
	sor back one space, then re-select the correct number.
9.	When you have made your selection of both Receiving and
	Transmitting CTCSS tone pairs, press the [VOL/SEL] key
	to save the new setting and exit to normal operation.

NOTE: The FTM-10Rdoes not recognize the order of the 1st tone and the 2nd tone. In other words, for example, the FTM-10Rconsiders both CTCSS pairs “10, 35” and “35, 10” to be identical.
