10Advanced OperationEPCS (Enhanced Paging & Code Squelch) OperationThe FTM-7250DR 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 the [MHz(SETUP)] key to enter theSet mode.2. Rotate the DIAL knob to select “PAG CD-R 29” forthe Receiving CTCSS Tone Pair or “PAG CD-T 30”for the Transmitting CTCSS Tone Pair.3. Press the [MHz(SETUP)] key momentarily to en-able adjustment of this Set Mode Item.4. Rotate the DIAL knob to set the CTCSS Tonenumber, which corresponds to the first tone of theCTCSS Tone Pair.5. Press the [BAND(SQL)] or [V/M(MW)] key, thenrotate the DIAL knob to set the CTCSS Tone num-ber, which corresponds to the second tone of theCTCSS Tone Pair.6. Press and hold the [MHz(SETUP)] key to lock in that tone and exit to normal operation.Note: The FTM-7250DR does not recognize the order of the 1st tone and the 2nd tone.In other words, for example, the FTM-7250DR considers both CTCSS pairs “05,47” and “47, 05” to be identical.
