15 OTHER FUNCTIONS DTCS code squelch operation The tone squelch opens only when you receive a signal that includes a matching DTCS code in the FM or FM narrow (FM-N) mode. You can silently wait for calls from others using the same tone. Also, a reversed tone squelch function mutes the squelch when you receive a signal including a matching DTCS code. Step 1. Setting the DTCS code [MENU] > SET > DUP/TONE... > DTCS Code 1. Push [VFO/MHz] to enter the VFO mode. 2. Push [MODE] to select the FM or FM-N mode. 3. Rotate [DIAL] to set an operating frequency. 4. Push [MENU]. 5. Select "DUP/TONE..." in the "SET" menu. 6. Select "DTCS Code." Step 2. Using the DTCS code squelch 1. Push [QUICK]. 2. Select "TONE." 3. Select the DTCS code type. 7.

About the DTCS code types indication •• DTCS: Enables the DTCS Squelch function. •• DTCS-R: Enables the Reverse DTCS Squelch function. •• DTCS(T) ("DTCS" blinks): When you transmit, the selected DTCS code is superimposed on your normal signal. When you receive, the function is OFF. •• TONE(T)/DTCS(R) ("T-DTCS" is displayed, "T" blinks.): When you transmit, the selected subaudible tone is superimposed on your normal signal. When you receive, the DTCS squelch opens only for a signal that includes a matching DTCS code and polarity. (Audio is heard) •• DTCS(T)/TSQL(R) ("D-TSQL" is displayed, "D" blinks.): When you transmit, the selected DTCS code is superimposed on your normal signal. When you receive, the tone squelch opens only for a signal that includes a matching tone frequency. (Audio is heard) 15-9
