SIGNALING Quiet Talk (QT)/ Digital Quiet Talke (DQT): Your dealer may have programmed QT or DQT signaling on your transceiver channels. QT and DQT signals allow you to ignore (not hear) calls from other parties who are using the same channel. MDC-1200: MDC-1200 is a data system using Audio Frequency Shift Keying (AFSK). OPTIONAL SIGNALING Your dealer may also program several types of optional signaling for your transceiver channels. 5-Tone Signaling: Refer to "5-TONE SIGNALING" on page 20. DTMF Signaling: DTMF Signaling opens the squelch only when the transceiver receives a call containing a matching DTMF code. FleetSync Signaling: Refer to "SELCALL (SELECTIVE CALLING)" on page 16.
