FM REPEATER USE
Hi Operation
A repeater amplifies received signals and transmits
them at a different frequency. When using a re-
peater, the transmit frequency is shifted from the
receive frequency by the offset frequency. (p. 28) It
is convenient to program repeater information into a
memory channel. (p. 30)
@ Select the desired band as the main band with
the [M/S] switch.
(2) Push [FM/RPT] to select FM mode.
@) Set the receive frequency (repeater output fre-
quency). (p. 21)
@ Push [FUNC] then [FM/RPT*-DUP] to select
— duplex or push them again for + duplex.
- 'DUP —" or "DUP +" appears to indicate the transmit
frequency for minus shift or plus shift, respectively.
- The U.S.A. and Australia versions have an auto
repeater function. (p. 28)
Hz Tone information
SUBAUDIBLE TONE
(U.S.A. and Australia versions only)
@ Push [TONE] to turn the subaudible tone encod-
er ON.
(2) Set the tone frequency if desired.
- Push [FUNC] then [TONE*SET].
Set mode is
selected.
Tone encoder
frequency appears.
- Rotate the tuning dial to select the desired tone
frequency.
- Push [CHECK] to exit the set mode.
-For the U.S.A. and Australia versions, push
[FM/RPT] to set the pre-programmed duplex direc-
tion and to turn the subaudible tone encoder ON.
See below.
(©) Push and hold [PTT] to transmit.
- Push and hold [CHECK] to check whether the other
station's transmit signal can be directly received or
not.
- The displayed frequency automatically changes to
the transmit frequency (repeater input frequency).
- When the repeater requires a tone, see the section
below.
-lf "DUP—" or "DUP+" blinks, confirm the offset
frequency.
© Release [PTT] to receive.
@ To return to simplex, push [FUNC] then [DUP]
once or twice to clear the "DUP" indicator.
-For the U.S.A. and Australia versions, push
[FM/RPT] to cancel the "DUP" and "T" settings.
(3) Push [TONE] to turn the subaudible tone encod-
er OFF.
e Subaudible tone frequency list (Unit: Hz)
192.8 | 233.6
203.5 | 241.8
210.7 | 250.3
DTMF TONES (HM-14 is required.)
Push the desired digit keys on the microphone in
sequence to transmit DTMF tones.
1750 Hz TONE (Europe and Sweden versions only)
Push [TONE] for 1-3 sec. to transmit a 1750 Hz tone
call signal.
EZ One-touch repeater (U.S.A. and Australia versions only)
The U.S.A. and Australia version's repeater settings
(DUP+ or DUP— and tone encoder ON) can be
activated by simply pushing [FM/RPT] in FM mode.
The display shows
— duplex is selected to
the one-touch repeater
function.
The duplex direction setting is common for each
band. Set the desired duplex direction as follows:
@) Push [FUNC] then [TONE*SET] to enter set
mode.
(2) Push [TONE] once to select the subaudible tone
frequency setting display.
(3) Rotate the tuning dial to select the desired du-
plex direction.
(4) Push [CHECK] to exit the set mode.
