3 BASIC OPERATION@ Repeater operation© GeneralWhen using a repeater, the transmit frequency is shifted fromthe receive frequency by the offset frequency. It is convenientto program repeater information into memory channels(p. 17).® Set the receive frequency (repeater output frequency).@® Push [FUNC] + (@DUP] once to select —- DUP or twice toselect DUP.*“— DUP” or “DUP” appears to indicate the transmit frequency forminus shift or plus shift, respectively.* When the auto repeater function is in use (U.S.A. version only)this selection and step @ are not necessary (p. 16).@ Push [FUNC] + [OT/TSQL] to activate the subaudible toneencoder, according to repeater requirements.* Optional for Europe, U.K. and Italy versions.* Refer to the addendum for a list of available tone frequencies.@ Push and hold [PTT] to transmit.*The displayed frequency automatically changes to the transmitfrequency (repeater input frequency).* The operating condition is automatically programmed into the re-peater memory (p. 11).* If “OFF” appears, check the offset frequency (p. 16).® Release [PTT] to receive.© Push and hold [MONI] to check whether the other station’stransmit signal can be directly received or not.© Tone informationSome repeaters require a tone to be accessed. In this case,precede step @ at left with the required tone.DTMF TONESWhile pushing [PTT], push the desired digit key(s) to transmitDTMF tones* The transceiver has 5 OTMF memory channels. See p. 20 for de-tails.1750 Hz TONE (Europe and Italy versions only)While pushing [PTT], push and hold [MONI] for 1 to 2 sec. totransmit a 1750 Hz tone signal.© Setting subaudible tones vena SETMODESome repeaters require subaudible tones to be accessed.Subaudible tones are superimposed over your normal signaland must be set in advance. This setting is an option forEurope and Italy versions.@ Push [VFO] to select VFO mode.® Push [FUNC] + [@SET] to enter set nitom eee H 1h 1G@ Push [A] or [V] until “TO” appears.@ Rotate [DIAL] to select the desiredsubaudible tone. 3Cu t© Push [(vFo)CLR] to set the condi- |(- 7 { { Tetion and to exit set mode.
