1750 Hz tone
To access some European repeaters, the transceiver must
transmit a 1750 Hz tone burst. For such repeaters, perform
the following.
• This tone can be use as a ‘Call signal’ in countries out of Europe.
q
Push
[SET]
to enter the Set mode.
w
Rotate
[DIAL]
to select the DTMF key item, then rotate
[VOL]
to set to “t-CALL.”

Tone call setting
DTMF key setting
e
Push
[V/M/C]
to return to the frequency display.
r
Set the receive frequency
(repeater output frequency)
.
t
Set the shift direction of the transmit frequency.
(–DUP or
+DUP; see p. 26 for details.)
y
While continuing to push
[PTT]
, push
[MONI]
(BAND) to
transmit a 1750 Hz tone burst signal.
• If “OFF” appears, check the frequency offset or shift direction.
(p. 26)
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
u
Push and hold
[PTT]
to transmit.
i
Release
[PTT]
to receive.
o
Push and hold
[MONI]
(BAND) to check whether the other
station’s transmit signal can be received directly or not, by
listening on the repeater input frequency.
✔
CONVENIENT! (For the IC-T70E only)
q
Set the receive frequency
(repeater output frequency)
.
w
Set the shift direction of the transmit frequency.
(–DUP or
+DUP; see p. 26 for details.)
e
Push
[PTT]
briefly, then push and hold
[PTT]
again for 1 to
2 sec. to transmit a 1750 Hz tone burst signal.
• If “OFF” appears, check the frequency offset or shift direction.
(p. 26)
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
r
Push and hold
[PTT]
to transmit; release to receive.
