EPCS (Enhanced Paging & Code Squelch) OperationThe FT-2980R includes an Enhanced CTCSS tone encoder/decoder and a dedicatedmicroprocessor providing paging and selective calling features. This allows you to placea call to a specific station (Paging), and to receive calls of your choice directed only toyou (Code Squelch).The paging and code squelch systems use two pairs of (alternately switched) CTCSStones which are stored in the pager memories. Basically, your receiver remains silentuntil it receives the CTCSS tone pair that matches those stored in the Receiving PagerMemory. The squelch then opens so the caller is heard, and the paging ringer immediatelysounds, if activated. When you close the PTT switch to transmit, the CTCSS tone pairwhich 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 Operation1. Press and hold in the [MHz(SET)] key for one second to enter the Set mode.2. Rotate the DIAL knob to select “34 PAG.CDR” for theReceiving CTCSS Tone Pair or “35 PAG.CDT” for theTransmitting CTCSS Tone Pair.3. Press the [MHz(SET)] key momentarily to enable ad-justment of this Set Mode Item.4. Rotate the DIAL knob to set the CTCSS Tone numberwhich corresponds to the first tone of the CTCSS TonePair.5. Press the [REV(DW)] or [LOW(A/N)] key, then rotate theDIAL knob to set the CTCSS Tone number which corre-sponds to the second tone of the CTCSS Tone Pair.6. Press and hold in the [MHz(SET)] key for one second tolock in that tone/code and exit to normal operation.The FT-2980R does not recognize the order of the1st tone and the 2nd tone. In other words, for ex-ample, the FT-2980R considers both CTCSS pairs “10, 35” and “35, 10” to be iden-tical.CTCSS Tone NumberNo. Hz No. Hz No. Hz No. Hz No. Hz01 67.0 11 94.8 21 131.8 31 171.3 41 203.502 69.3 12 97.4 22 136.5 32 173.8 42 206.503 71.9 13 100.0 23 141.3 33 177.3 43 210.704 74.4 14 103.5 24 146.2 34 179.9 44 218.105 77.0 15 107.2 25 151.4 35 183.5 45 225.706 79.7 16 110.9 26 156.7 36 186.2 46 229.107 82.5 17 114.8 27 159.8 37 189.9 47 233.608 85.4 18 118.8 28 162.2 38 192.8 48 241.809 88.5 19 123.0 29 165.5 39 196.6 49 250.310 91.5 20 127.3 30 167.9 40 199.5 50 254.125CTCSS/DCS/EPCS OperationFT-2980R Operating Manual
