8Advanced OperationFTM-3100R Advance ManualEPCS (Enhanced Paging & Code Squelch) OperationThe FTM-3100R includes an Enhanced CTCSS tone encoder/decoder and a dedicatedmicroprocessor providing paging and selective calling features. This allows placing a callto a specific station (Paging), and choosing to receive calls directed only to you (CodeSquelch).The paging and code squelch systems use two pairs of (alternately switched) CTCSStones, which are stored in the pager memories. Basically, your receiver remains silent untilit 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 isstored in the Transmitting Pager Memory will be transmitted automatically.On the paged radio, the squelch will close automatically after the incoming page ends.Storing CTCSS Tone Pairs for EPCS Operation1. Press and hold in the [MHz(SETUP)] key forone second to enter the Set mode.2. Rotate the DIAL knob to select “PAG CD-R21” for the Receiving CTCSS Tone Pair or“PAG CD-T 22” for the Transmitting CTCSSTone Pair.VOLDIALD W M WSETUPREVSQL TXPO V / MM H z3. Press the [MHz(SETUP)] key momentarily toenable adjustment of this Set Mode Item.4. Rotate the DIAL knob to set the CTCSSTone number, which corresponds to the firsttone of the CTCSS Tone Pair.5. Press the [SQL] or [V/M(MW)] key, then ro-tate the DIAL knob to set the CTCSS Tonenumber, which corresponds to the secondtone of the CTCSS Tone Pair.6. Press and hold in the [MHz(SETUP)] key for one second to lock in that tone and exit tonormal operation.Note: The FTM-3100R does not recognize the order of the 1st tone and the 2nd tone. Inother words, for example, the FTM-3100R considers both CTCSS pairs “05, 47”and “47, 05” to be identical.
