30 FT-8800R Operating ManualCTCSS/DCS O PERATION1) Your repeater may or may not re-transmit a CTCSS tone - some systems just useCTCSS to control access to the repeater, but don’t pass it along when transmit-ting. If the S-Meter deflects, but the FT-8800R is not passing audio, repeat steps “1”through “4” above, but rotate the “Main” DIAL knob so that “ENC” appears - this willallow you to hear all traffic on the channel being received.2) You may select the Tone Squelch mode (ENC, ENC.DEC, or DCS) on the “Main”band using the microphone’s [P3] key.DCS O PERATIONAnother form of tone access control is Digital Code Squelch, or DCS. It is a newer, moreadvanced tone system which generally provides more immunity from false paging thandoes CTCSS. The DCS Encoder/Decoder is built into your FT-8800R, and operation isvery similar to that just described for CTCSS. Your repeater system may be configured forDCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use trans-ceivers equipped with this advanced feature.Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS andthat you select a tone code.1. Press the [SET] key momentarily to enter the Set mode.2. Rotate the “Main” band DIAL knob to select Menu #41 (TONE MTONE MTONE MTONE MTONE M).3. Press the “Main” band DIAL knob momentarily, then rotate the “Main” band DIALknob until “DCS” appears on the display; this activates the DCS Encoder/Decoder.4. Now, press the “Main” band DIAL knob momentarily, then rotate the “Main” bandDIAL knob to select Menu #10 (DCS.CODDCS.CODDCS.CODDCS.CODDCS.COD).5. Press the “Main” band DIAL knob momen-tarily to enable the adjustment of the DCScode.6. Rotate the “Main” band DIAL knob to se-lect the desired DCS Code (a three-digitnumber).7. When you have made your selection, pressand hold in the “Main” band DIAL knobfor 1/2 second to save the new setting andexit to normal operation.1) Remember that the DCS is an Encode/Decode system, so your receiver willremain muted until a matching DCS code is received on an incoming transmis-sion. Switch the DCS off when you’re just tuning around the band!2) You may select the DCS mode on the “Main” band by the microphone’s [P3] key.CTCSS OPERATIONDCS CODE023 025 026 031 032 036 043 047 051 053054 065 071 072 073 074 114 115 116 122125 131 132 134 143 145 152 155 156 162165 172 174 205 212 223 225 226 243 244245 246 251 252 255 261 263 265 266 271274 306 311 315 325 331 332 343 346 351356 364 365 371 411 412 413 423 431 432445 446 452 454 455 462 464 465 466 503506 516 523 526 532 546 565 606 612 624627 631 632 654 662 664 703 712 723 731732 734 743 754 – – – – – –
