1750 Hz tone
To access most European repeaters, the transceiver
must transmit a 1750 Hz tone. For such European re-
peaters, do the following procedures.
• This tone can also be used as a ‘Call signal.’
For only the ID-51E:
Push [PTT] briefly, then hold down [PTT] to transmit a
1750 Hz tone burst signal.
q
Push D-pad(
) to select the root item (“DTMF/T-
CALL”), and then push D-pad(Ent).

(Ent)
w
Push D-pad(
) to select “DTMF Memory,” and then
push D-pad(Ent).
e
Rotate [DIAL] to select “T-CALL,” and then push
D-pad(Ent) to set.
r
Push [MENU]
to exit the MENU screen.
t
Rotate [DIAL] to set the receive frequency (repeater
output frequency).
y
Set the duplex offset direction. (p. 15-5)
• “DUP–” or “DUP+” appears.
u
While holding down [PTT], push [SQL] to transmit a
1750 Hz tone signal.
• If “OFF BAND” appears, check the frequency offset or
shift direction. (pp. 15-4, 15-5)
• While transmitting, the displayed frequency automati-
cally changes to the transmit frequency (repeater input
frequency).
i
Hold down [SQL] to check whether the other sta-
tion’s transmit signal can be received directly or not,
by listening on the repeater input frequency.
• While monitoring, the TX/RX indicator lights green, and
the S/RF meter dot blinks.
• While monitoring, the displayed frequency automatically
changes to the transmit frequency (repeater input fre-
quency).
• If you can hear the other station, you may want to change
to the Simplex mode and contact directly.
o
Push [PTT] to transmit.
!0
Release [PTT] to receive.

[SQL]
Push [MENU]
.
Push D-pad(
) to
select, then push
D-pad(Ent).
Push D-pad(
) to
select, then push
D-pad(Ent).
[DIAL]
Rotate [DIAL] to set the
receive frequency.
Set the duplex offset di-
rection.
While holding down
[PTT], push [SQL] to
transmit a 1750 Hz
tone signal.
