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. 1820).
Set the operating band and receive frequency (repeater
output frequency).
Push [MULTI] to enter duplex set mode.
•“D appears; if T appears instead of D push [MULTI()] to se-
lect D.
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 , , and are not necessary (p. 17).
Push [MULTI()] to select tone set mode.
•“T appears.
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.
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).
Release [PTT] to receive.
Push and hold [SQL] to check whether the other stations
transmit signal can be directly received or not.
D Tone information
Some repeaters require a tone to be accessed. In this case,
precede step
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 dont 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.
