CTCSS/DCS/EPCS OPERATION

EPCS (ENHANCED PAGING & CODE SQUELCH)

The VX-8Rincludes an Enhanced CTCSS tone encoder/decoder and a dedicated microprocessor 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 switch to transmit, the CTCSS tone pair that is stored in the Transmitting Pager Memory will be transmitted automatically.

On the paged radio, the Code Squelch will close automatically after the incoming page ends. Meanwhile, on the paging radio, the Enhanced Paging and Code Squelch system will be disabled after the PTT switch is released after the paging transmission. You may re-activate the Enhanced Paging and Code Squelch system again.

STORING THE CTCSS TONE PAIRS FOR EPCS OPERATION

1.Press and hold the key for one second to enter the Set Mode.

2.Rotate the DIAL knob to select Set

Mode Item 67: PAGER CODE-RX for the Receiving CTCSS Tone

Pair or Set Mode Item 68: PAGER CODE-TXfor the Transmitting CTCSS Tone Pair.

3.Press the key briefly to enable adjustment of this Set Mode Item.

4.Rotate the DIAL knob to set the CTCSS Tone number which

corresponds to the first tone of the CTCSS Tone Pair.

5. Press the key (“¾” icon moves to the right), then rotate the DIAL knob to set the CTCSS Tone number, which corresponds to the second tone of the CTCSS Tone Pair.

6. Press the PTT switch to save the new setting and exit to normal operation.

The VX-8R does not recognize the order of the 1st tone and the 2nd tone. In other words, for example, the VX-8R considers both CTCSS pairs “10, 35”

and “35, 10” to be identical.
