3799DTMF MEMORYThe transceiver has three methods of transmitting a DTMFcode sequence. Select a desired option in the Set mode.q Push [FUNC](M), and then [SET](8) to enter the Set mode.wPush [p] or [q] to select the DTMF TX key item (dmt).eRotate [VOL] to select a desired option.• dmt.k : Transmits the appropriate DTMF code assigned to apushed key.• dmt.m : Transmits the programmed DTMF code sequence in theDTMF memory channel assigned to a pushed key.• dmt.t : No DTMF code can be transmitted. However, whileholding down [PTT], pushing either the [p] or [q]transmits a 1750 Hz tone burst signal.r Push [# ENT] to exit the Set mode.D Manual DTMF code transmissionFirst, set the DTMF TX key to “dmt.k” in the Set mode.➥ While holding down [PTT], push the desired keys to trans-mit a DTMF code sequence manually.• Push [0]–[9] for “0”–“9,” [MONI] for “A,” [p] for “B,” [q] for “C,”[VFO/MR/CALL] for “D,” [M] for “M,” and [# ENT] for “#.”D Using a DTMF memory channelFirst, set the DTMF TX key to “dmt.m” in the Set mode.➥ While holding down [PTT], push one of the keys to trans-mit the programmed DTMF code sequence in the DTMFmemory.• Pushing [0] to [9], [MONI](A), [p](B), [q](C), [VFO/MR/CALL](D), [M](E), or [# ENT](F) transmits a DTMF code channel(d0–d9, dA, dB, dC, dD, dE or dF) respectively.D 1750 Hz toneTo access some European repeaters, the transceiver musttransmit a 1750 Hz tone burst signal.• This tone can be used as a ‘Call signal’ in countries out of Europe.First, set the DTMF TX key to “dmt.t” in the Set mode.➥ While holding down [PTT], hold down either the [p] or[q] for 1 or 2 seconds to transmit a 1750 Hz tone burstsignal.• The tone is transmitted until you release the key.■ Transmitting a DTMF code sequence 1234567810111213141516171819
