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 info into memory channels (pgs. 18–20).
➀
Set the operating band and receive frequency (repeater
output frequency).
➁
Push [MULTI] to enter duplex set mode.
• “D” appears; if “T” appears instead of “D” push [MULTI(
↕
)] to se-
lect “D.”
➂
Push [MULTI(
↔
)] (or rotate [DIAL]) one or more times to
select DUP ( plus duplex) or –DUP (minus duplex).
• When the auto repeater function is in use (USA version only)
steps
➁
,
➂
,
➃
and
➄
are not necessary (p. 17).
➃
Push [MULTI(
↕
)] to select tone set mode.
• “T” appears.
➄
Push [MULTI(
↔
)] (or rotate [DIAL]) to activate the sub-
audible tone encoder according to repeater requirements.
• Refer to the table of subaudible tone frequencies on the following
page.
➅
Push and hold [PTT] to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If “OFF” appears, check the offset frequency (p. 16).
➆
Release [PTT] to receive.
➇
Push and hold [SQL] to check whether the other station’s
transmit signal can be directly received or not.
D
Tone information
Some repeaters require a tone to be accessed. In this case,
precede step
➅
at left with the required tone.
DTMF TONES
While pushing [PTT], push the desired digit key(s) to transmit
DTMF tones.
• The transceiver has 9 DTMF memory channels. See p. 21 for de-
tails.
1750 Hz TONE
While pushing [PTT], push and hold [MULTI] for 1 to 2 sec.
to transmit a 1750 Hz tone signal.
✔
Convenient
Tone scan function:
When you don’t know the subaudible
tone used for a repeater, the tone scan is convenient for de-
tecting the tone frequency.
Push [
(RIT)
TSCAN)] for 1 sec. to activate the tone scan. See
p. 26 for more details.
