4 BASIC OPERATION
W Operating through a
repeater
When operating through a repeater, set the transceiver
to duplex. Some repeaters require a subaudible tone,
1750 Hz tone or DTMF tone.
— —
Set the operating frequency. (p. 14)
X Push [DUP] for — duplex and again for +duplex.
e"DUP—" or "DUP" appears.
"DUP—": Transmit freq. =Receive freq. — Offset freq.
"DUP": Transmit freq. = Receive freq. + Offset freq.
3) Set the desired offset frequency.
e See at right for details.
4) Push and hold [PTT] to transmit.
*The operating frequency on the function display
automatically changes to the transmit frequency
(repeater input frequency).
e See the right page when the repeater requires a
tone.
Q
Release [PTT] to receive.
e Push [MONI] to check whether the transmit
frequency (repeater input frequency) is busy or
not.
6) To return to simplex, push [DUP] until "DUP" disap-
pears.
usne SET MODE
e OFFSET FREQUENCY
SETTING
Push [BAND] to select VHF or UHF.
Push [SET] several times until "DUP" blinks on the
function display as shown above.
e Refer to p. 13 for SET mode details.
Rotate the main dial to set the desired offset frequency.
e Use [V/MHz] for quick MHz setting.
Push any switch except [V/MHz], [SET] and [HI/LO], or
push PTT to set the value and to exit SET mode.
NOTE: When the transmit frequency is out of the
band, transmission is impossible and "oFF" appears
on the function display.
