[. . . ] Remember that the DCS is an Encode/Decode system, so your receiver will remain muted until a matching DCS code is received on an incoming transmission. Switch the DCS off when you’re just tuning around the band! 023 116 225 325 452 627 025 122 226 331 454 631 026 125 243 332 455 632 031 131 244 343 462 654 032 132 245 346 464 662 036 134 246 351 465 664 043 143 251 356 466 703 DCS CODE 047 051 053 054 145 152 155 156 252 255 261 263 364 365 371 411 503 506 516 523 712 723 731 732 065 162 265 412 526 734 071 165 266 413 532 743 072 172 271 423 546 754 073 174 274 431 565 – 074 205 306 432 606 – 114 212 311 445 612 – 115 223 315 446 624 – 16 FT-250R OPERATING MANUAL Advanced Operation TONE SEARCH SCANNING In operating situations where you don’t know the CTCSS or DCS tone being used by another station or stations, you can command the radio to listen to the incoming signal and scan in search of the tone being used. Two things must be remembered in this regard: You must be sure that your repeater uses the same tone type (CTCSS vs. Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s) transmitting on the repeater uplink (input) frequency in order to allow Tone Search Scanning to work. To scan for the tone in use: Set the radio up for either CTCSS or DCS Decoder operation (see the previous discussion). In the case of CTCSS, “T SQ will appear on the display; in the case of DCS, T SQ” “DCS will appear on the display. DCS” DCS Press the [F/L] key, then immediately press the [2(CODE)] key to select the “TN SET TN SET” Menu item (when TONE SQL is selected) or “DCS SET (during DCS operation). DCS SET” Press the [F/L] key, then press and hold in the [ (MHz)] or [ (MHz)] key to start scanning for the incoming CTCSS or DCS tone/code. When the radio detects the correct tone or code, it will halt on that tone/code, and audio will be allowed to pass. Press the [F/L] key to lock in that tone/code. Press the [F/L] key, then press the PTT key to save the new settings and exit to normal operation. If the Tone Scan feature does not detect a tone or code, it will continue to scan indefinitely. When this happens, it may be that the other station is not sending any tone. You can press the PTT switch to halt the scan at any time. You also can press the MONI key during Tone Scanning to listen to the (muted) signal from the other station. When you release the MONI key, Tone Scanning will resume after about a second. CTCSS/DCS BELL OPERATION During CTCSS Decode or DCS operation, you may set the FT-250R up such that a ringing “Bell” sound alerts you to the fact that a call is coming in. Here is the procedure for activating the Bell will ring in accordance with this programming. Set the transceiver up for CTCSS Decode (“TONE SQL”) or DCS operation, as described previously. Adjust the operating frequency to the desired channel. Press the [F/L] key, then press the [0(SET)] key to activate the Set mode. Rotate the DIAL to select Menu Item #18 (“BELL BELL”). BELL Press the [F/L] key to enable adjustment of the Bell ringer. Rotate the DIAL to set the desired number of rings of the Bell. [. . . ] Available Values: ON/OFF Default: OFF Set Item 24 [CLK SFT] Function: Shifting of CPU clock frequency. Available Values: ON/OFF Default: OFF MONI: This function is only used to move a spurious response “birdie” should it fall on a desired frequency.
