34D Setting DTCS polarityFor DTCS operation, the polarity setting is also configurable,as well as the code setting. If the polarity is different, theDTCS squelch will never open, even when receiving a signalthat includes a matched DTCS code.q Push [FUNC](M), and then [SET](8) to enter the Set mode.wPush [p] or [q] to select the DTCS polarity item (dtP).eRotate [VOL] to set the desired polarity setting to “dtP.nn”(normal), “dtP.nR” (TX: normal, RX: reverse), “dtP.Rn” (TX: re-verse, RX: normal) or “dtP.RR” (reverse).r Push [# ENT] to exit the Set mode.NOTE: When you use the DTCS encoder, the DTCS po-larity setting affects only transmitting.D Operationq Set a desired operating frequency, and then a CTCSS toneor a DTCS code.w Push [FUNC](M), and then [TONE](1).• Repeat step w one or more times to activate a desired tonefunction.e Operate the transceiver in the normal way.8 TONE SQUELCH AND POCKET BEEPTX/RX: Normal polarity TX: Normal, RX: ReverseTX: Reverse, RX: Normal TX/RX: Reverse polarityFunction OFFTone squelch withpocket beepTone squelchDTCS encoderDTCS squelchDTCS squelch withpocket beepRepeater tone: Push , and then .
