REPEATER AND DUPLEX OPERATIONS
8-2
A repeater receives signals and on one frequency, and
then retransmits them on a different frequency. When
using a repeater, the transmit frequency is shifted
from the receive frequency by a frequency offset.
A repeater can be accessed using the Duplex function
by setting the transceiver’s offset to the same value as
the repeater’s offset.
See Section 4 for details on accessing a D-STAR
repeater.
1. Push [V/M] several times until you enter the VFO
mode.
2. Push [BAND].
• Enters the Band Select mode.
3. Rotate [DIAL] to select the operating band.
4. Push [BAND] again.
• Returns to the frequency display.
5. Push [MODE] several times until you select the
FM mode.
6. Rotate [DIAL] to set the receive frequency
(Repeater output frequency).
L When the Auto Repeater function (usable in only the
USA version) is turned ON, skip steps 7 ~ 12. (p. 8-5)
7. Push [QUICK].
8. Rotate [DIAL] to select “DUP,” then push [ï].
• Displays the Duplex direction setting window.
9. Select the offset direction, then push [ï].
• Displays “D–” or “D+.”
L You can set the frequency offset in the MENU screen.
(DUP/TONE... > Offset Freq) (p. 9-16)
10. Push [QUICK].
11. Select “TONE,” then push [ï].
• Displays the Tone function setting window.
12. Select “TONE,” then push [ï].
• Turns ON the repeater tone, and “TONE” is displayed.
L You can set the tone frequency in the MENU screen.
(DUP/TONE... > Repeater Tone) (p. 9-16)
13. Operate in the normal way.
L Subaudible tone is superimposed on your transmit signal.

TIP:
• When the Repeater tone frequency or the
frequency offset is changed, the tone or offset for
Auto Repeater function is also changed.
• If the offset value will cause the transmit frequency
to be out of the band, “OFF BAND” is displayed on
the display when [PTT] is pushed, and transmit will
be inhibited. (p. 8-5)
