3 BASIC OPERATION
@ Repeater operation
© General
When using a repeater, the transmit frequency is shifted from
the receive frequency by the offset frequency. It is convenient
to program repeater information into memory channels
(p. 17).
® Set the receive frequency (repeater output frequency).
@® Push [FUNC] + (@DUP] once to select —- DUP or twice to
select DUP.
*"— DUP" or "DUP" appears to indicate the transmit frequency for
minus 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 tone
encoder, 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 transmit
frequency (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's
transmit signal can be directly received or not.
© Tone information
Some repeaters require a tone to be accessed. In this case,
precede step @ at left with the required tone.
DTMF TONES
While pushing [PTT], push the desired digit key(s) to transmit
DTMF 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. to
transmit a 1750 Hz tone signal.

Some repeaters require subaudible tones to be accessed.
Subaudible tones are superimposed over your normal signal
and must be set in advance. This setting is an option for
Europe and Italy versions.
@ Push [VFO] to select VFO mode.
